Description

The invention relates to the field of agriculture, to technologies for raising animals and poultry with selective control of their live weight during the process of growing in livestock and poultry facilities and can be used in industries of livestock and poultry.

A known method and device for growing birds, in which the temporary productivity sensor of one bird contains load cells and weighing counters (RF patent No. 2340172 C1, A01K 29/00. Method and device for growing birds / Dubrovin A.V., Musin A. M et al. // Published on October 12, 2008. Bull. No. 14). In the poultry growing room, constructions with load-measuring sensors in the room and with counters of weighing quantities are placed (for example, the number of randomly planted only one bird on a given load-measuring sensor. At the output of the second adder, a random signal of the total live weight of the elements (weighing devices ) animals or birds. At the output of the counter, a signal is generated of the number of weighings of animals or birds. At the output of the second division element, an estimate of the average minutes per day cultivation of live weight per animal or poultry (chicken). The first audio output poultry productivity temporary closure sensor at a time of the current day (cultivation) of the measured signal is formed of one of poultry.

The disadvantage of this technical solution is the low accuracy of measuring the average live weight of a bird in a herd of livestock.

The reason for this is the important general and already complex task of the invention and the lack of information about taking into account the statistical characteristics of the process, essentially the selective weighing of individual birds that accidentally fell on the load-measuring elements of the device and the mathematically reliable assessment of this information when judging the live weight of everything grown in the house livestock. Also the reason for this is the assumption adopted by default in the specified analogue on the quite sufficient accuracy of the technical means listed in the analogue. However, for high-precision technologies of the agro-industrial complex (AIC), one should have new technical solutions with the greatest accuracy of measurement, including measuring the live weight of the livestock for subsequent high-precision control of feeding, microclimate, heating of young animals and many other interconnected technological processes, including hours the so-called precision technologies of the agricultural sector.

In agricultural production facilities, for example, in industrial poultry houses, up to several tens of thousands of birds are simultaneously raised or kept, therefore, even a slight error in determining the real value of the live weight of the entire livestock in the house based on the results of weighing random sample individuals leads to errors in the control of many technologies and technological processes. In this case, the additional costs that are associated only with the errors in estimating the total live weight of the livestock in the production room according to the results of selective weighing of random single animals or birds from the total population of them in the production room reach large values and become comparable in cost to other components of production costs. Weighing the whole population of animals or birds is almost impossible. Weighing the entire livestock leads either to excessive labor and other operational (as well as additional capital) costs, or it will injure the livestock (stress, direct loss of livestock productivity, loss of part of the livestock itself and mechanical damage to individuals that are not allowed by the growing technology). Therefore, there is no need to even talk about any substantial feasibility of such an approach that seems theoretically ideal at first glance. Initially, only one individual animal or bird can fit on the scales when weighing, it allows to eliminate the ambiguity of the weighing result if two or more individuals hit the weighing platform at the same time. Therefore, the design of the weighing platform of the scales should initially allow it to hit only one, the only, in the context of this invention, a single individual from all animals or birds of the herd.

The objective of the invention is automated with a given accuracy and accuracy with an estimate of the average herd live weight of an animal or bird with random selective weighing of an arbitrary individual of the herd for subsequent precise control of technologies and technological processes of animal husbandry and poultry farming.

As a result of the use of the invention, the value of the signal for estimating the average live weight of an animal or bird is established over the entire herd of livestock in the production room or in its habitat with a given certainty, and the practical opportunity is provided with a given accuracy to automatically receive a signal for estimating the average live weight of an animal or bird during random selective weighing of herds during the technology of growing herds of animals or poultry for subsequent precise control technologies and technological processes of livestock or poultry farming.

The essence of the invention is illustrated by example. The table of values of the Laplace function is the probability that a random variable will take on a value belonging to a given interval. When solving problems in probability theory, as a rule, it is required to find the value of the Laplace function from the known value of the argument, or, conversely, from the known value of the Laplace function, it is required to find the value of the argument. To do this, use the table of values of the Laplace function. The table of values of the Laplace function is indispensable in the study of probability theory, since it is difficult to solve the integral (Laplace function), and it is simply impossible to remember the table of values of the Laplace function. Laplace function for different values of t: F (-t) = - F (t). This is a normal distribution function (see: website: webmath.ru).

By “reliability”, the level of reliability is understood as an indicator of the probability that the true value of the studied parameter of the general population falls into the confidence interval. The higher the confidence level set, the larger the sample should be. The confidence interval is understood as the range into which the true value of the studied parameter of the general population falls at a given level of confidence. The smaller it is, the larger the sample should be. The confidence interval is called the "permissible error" of the sample. Its researchers ask (appoint) themselves or calculate by special formulas depending on a given sample size. Measured "permissible error" in percentage points - p.p. Often they are confused with percentages, -%. This is a serious mistake (see: site: cityexclusive.ru> books / igor-berezin / dostovernost- ...).

The magnitude of statistical errors is determined as follows. Suppose we need to evaluate a certain parameter p (live weight). For this purpose, a statistical measurement (live weight) is carried out on sample n. Note that the number p is the absolutely exact value of the desired parameter, which is not known and cannot be known in principle, but which must be estimated by the method of statistical measurements. The confidence probability and the corresponding confidence interval are determined as follows. By conducting a statistical measurement, we can obtain an estimate of p * of our desired parameter p. Our estimate of p * will be somewhere near the true value of the parameter p, and most likely will not be exactly equal to p. The distribution of the possible estimates of the value of the desired parameter f (p *) obeys, in the general case, the normal (Gaussian) law. The value of σ is the so-called standard deviation (RMS), a value dependent on the sample size n: the larger the sample, the smaller this deviation. The area bounded by the Gaussian curve and the horizontal axis is equal to one. Consider the percentage A% of the area under the Gaussian curve near p in the range from p-x to p + x. With probability A%, the resulting estimate of p * will be in the range from p-x to p + x. Probability A% is called confidence probability. They say: with probability A%, the estimate p * will be in the interval between the lower boundary p-x and the upper boundary p + x near p. Or in abbreviated form - "p% x". The standard value of confidence probability A = 95% is accepted, in this case our interval will have borders% 2σ near p. Or -r% 2σ (advlab.ru> articles / article72.htm).

Selected characteristics, determined on the basis of a limited number of observations, can approach the true values of the characteristics of the general population only with a certain accuracy. The accuracy of the sample observation (experiment) can be set in units of the investigated value, in units of the sample value and in percent of the studied value or characteristic. The interval, in which in the general case can be arbitrary, is called confidence limits, and the corresponding probability is called confidence probability or, as they often say, reliability.

The probability of error characterizes the share of risk in assessing the true value of the estimated value and is often called the significance level. For convenience, the value of the confidence interval is set in fractions of the standard deviation. Then the confidence probability is defined as the area bounded by the normal distribution curve in the interval. The confidence interval is determined in the following sequence: the sampling parameter is calculated, the confidence probability is selected; determining the number corresponding to the selected value from the table of tabulated values of the standard normal distribution; compute confidence interval. With an increase in the number of measurements, the reliability of the experiment increases, and the confidence interval decreases. The table is used when it is impossible to form a definite opinion about the variance of the studied quantity. If, on the basis of a priori information or preliminary experiments, the dispersion value is known, then the necessary number of measurements is determined by the formula of random sampling error equal to half the length of the confidence interval, which guarantees the required reliability of the sample estimation result.

When processing numerical arrays of experimental results as random variables, the following sample estimates are used in practice:

- expected value

- variance

- asymmetry coefficient

- kurtosis coefficient

where x _i is the value of the result in the i-th experiment; N is the number of results in the array; σ _x - standard deviation:

The derivative of the expected value M _x and the variance D _x or the standard deviation σ _x is the coefficient of variation V, determined as a percentage by the formula:

The dispersion D _x , the standard deviation σ _x, and the coefficient of variation V are quantitative characteristics of the estimation of the dispersion of the values of the experimental results as a random variable and are used to study various actions with a random outcome. The asymmetry coefficient and the excess coefficient are characteristics of a higher order. The first characterizes the "slanting distribution", and the second - the degree of its "peaks". The statistical characteristics calculated from experimentally observed random variables and random functions do not carry information about the entire population, which is generally infinite, but only about a certain part of it — a sample whose elements were measured with certain errors. In this regard, as a result of the experiment, only some estimates of the parameters of the general population are obtained. Therefore, any sample estimate is a random variable, the accuracy of determination of which and possible errors in this case must be controlled. It should also be borne in mind that the calculated moments of distribution are point estimates of sample values, since each of them estimates the parameters of the general population using a single number. They allow us to judge the value of the calculated statistical characteristics at a given point and do not say anything about the possible limits of variation of the estimate itself.

Three basic requirements are imposed on estimates of random variables calculated as a result of the experiment: consistency, non-bias, and efficiency. It is believed that the estimate is consistent if, with increasing sample size, it tends to the true value in probability, is not biased if its mathematical expectation tends to the true value, and is effective when the estimate has the smallest dispersion compared to any other estimates. Of the two estimates, the one with the lower dispersion is more effective, i.e. whose values are scattered in a narrower interval.

The scattering level of the estimates is significantly affected by errors that occur during the experiment.

As is known, during selective observation there are three types of errors: gross, systematic, and random. Gross errors, which differ by a large deviation from the center of the grouping of samples, are screened out at the stage of the initial analysis of materials.

- истинное значение), которые, в свою очередь, состоят из суммы систематических δ и случайных ξ ошибок.The accuracy of measurements of any physical quantity is, as is known, characterized by absolute

and relative

errors (here

is the true value), which, in turn, consist of the sum of systematic δ and random ξ errors.

The systematic errors δ are constant in the determination of each member of the sample and depend on the technical level of the measuring equipment and experimental technique. These errors can be minimized by periodically calibrating the instruments using more advanced and improving the accuracy of the method for determining the studied variables.

Random errors are due to the influence of a large number of factors. Their appearance is not the same and random from measurement to measurement and cannot be previously taken into account due to their dependence on changes in the measurement conditions and the variability of the measured quantities themselves. However, with a sufficiently large number of experiments, the total value of random errors that vary approximately the same in the positive and negative directions approaches zero. The vast majority of random errors obey the normal distribution law with a mathematical expectation of "0". In the practice of agricultural machinery research, systematic and random errors are close to each other and together determine the measurement error. When assessing the accuracy of measurements, it is recommended to take into account the total error

where σ _ξ is the mean square deviation of the random variable ξ for the number of measurements n.

For the values determined indirectly - by the method of calculation from other measured random variables, the error estimation is carried out by calculating statistical estimates from the corresponding functional dependencies.

лишь с определенной точностью ε:Sample characteristics of M _x , σ _x , etc., determined on the basis of a limited number of observations, can approach the true values of the characteristics of the general population

only with a certain accuracy ε:

The accuracy of a sample observation (experiment) can be specified in units of measurement of the investigated value, in units of the sample value σ _x and in percent of the studied value or characteristic. A systematic error, being constant, may not be taken into account. The probability that the true value of the characteristics of the population is within the marked limits is

and is called the reliability of this assessment. Since the mathematical expectation of any sample is itself a random variable, it is useful to establish an interval in which, with a given degree of confidence, the value of the estimated parameter will be enclosed. The interval M _x + ε, in which in the general case can be arbitrary [a _i , b _i ], is called confidence limits, and the corresponding probability is called confidence probability or, as is often said, reliability. The confidence probability for convenience is denoted as

Accordingly, there is a probability of error, which is represented in the form of two halves of α / 2 on the distribution curve. The probability of error characterizes the share of risk in assessing the true value of the estimated value and is often called the significance level. For convenience, the confidence interval is set in fractions of the standard deviation ± zσr _z . Here, the quantity z is essentially Student's criterion t, or the argument of the Laplace function. Then the confidence probability is determined as the area bounded by the normal distribution curve in the interval ± zσ _z . Using the standard normal distribution formula

confidence probability is written as follows:

- оценка среднего значения генеральной совокупности.Where

- an estimate of the average value of the general population.

Confidence Interval for Variance

, выбирают доверительную вероятность 1-α определяют соответствующее выбранному значению (1-α) числом из таблицы табулированных значений стандартного нормального распределения; вычисляют доверительный интервал a≤M_к<b.The confidence interval is determined in the following sequence: the sampling parameter is calculated

, select a confidence probability of 1-α; determine the number corresponding to the selected value (1-α) from the table of tabulated values of the standard normal distribution; compute a confidence interval a≤M _to <b.

With an increase in the number of measurements, the reliability of the experiment increases, and the confidence interval decreases. The table is used when it is impossible to form a definite opinion about the variance of the studied quantity. If, on the basis of a priori information or preliminary experiments, ah, it is known, then according to the formula of random sample error equal to half the length of the confidence interval

determine the required number of measurements, guaranteeing the required reliability

The accuracy and reliability of the evaluation of selected characteristics should not be confused with the accuracy of the study, which is often calculated by the following formula:

where V is the coefficient of variation of sample observation,% (in the case of assessing accuracy for agricultural machines and processes it is considered sufficient if V = 3 ... 5%), δ is a systematic error.

The statistical characteristics calculated from experimentally observed random variables and random functions do not carry information about the entire population, which is generally infinite, but only about a certain part of it — a sample whose elements were measured with certain errors. In this regard, as a result of the experiment, only some estimates of the parameters of the general population are obtained. Therefore, any sample estimate is a random variable, the accuracy of determination of which and possible errors in this case must be controlled. It should also be borne in mind that the calculated moments of distribution are point estimates of sample values, since each of them estimates the parameters of the general population using a single number. They make it possible to judge the value of the calculated statistical characteristics at a given point and do not say anything about the possible range of variation of the estimate itself (see: 4. ORGANIZATION AND CARRYING OUT OF THE DISSERTATION STUDY. 4.5. The correctness of the mathematical processing of the experimental results is the key to the reliability of scientific provisions on the dissertation. Site: aspirinby.org).

When planning a sample observation with a predetermined value of the permissible sampling error, it is necessary to correctly evaluate the required sample size. This volume can be determined on the basis of the permissible error during selective observation based on a given probability P, which guarantees the permissible value of the error level (taking into account the method of organizing the observation). The formulas for determining the required sample size n can be easily obtained directly from the formulas of the marginal sampling error. So, from the expression for the marginal error (absolute, i.e., in units of measurement of a random variable, in this case in kg):

the sample size n is directly determined:

This formula shows that with a decrease in the marginal sampling error Δ, the required sample size n substantially increases, which is proportional to the variance σ ² and the square of the Student criterion t (see: site: grandars.ru>Statistics> Selective method).

If the value of confidence probability is given, then immediately by this value of the Laplace function the value of the specified argument of the Laplace function becomes known. Setting the value of the permissible sample error immediately gives the set value of the marginal error (absolute, i.e., in units of measurement of a random variable, in this case, in kg). In formula (18), only the value of the mean square deviation of a random variable, also in this case in kg, remains unknown for further calculations. Therefore, the required sample size n can be determined only after determining the standard deviation.

So, we have constructed a method for estimating the average live weight of an animal or bird in a herd during random selective weighing of an arbitrary individual of a herd, including random selective weighing of an arbitrary individual of an animal or bird herd and setting the signal for the technologically minimum amount of mandatory weighing, while setting a confidence signal, setting an acceptable signal the sampling error of measuring the average live weight of an individual according to the herd, according to a given signal of confidence probability form the corresponding signal l of the argument of the Laplace function, determine the fact signal of the individual placement event on the weighing platform of the scales and generate the weighing event signal, measure the number of weighing events of the individual herds and generate the signal of the number of weighings of the individual herds, measure the live weight of the arbitrary herds, form the signal of the measured live weight of the arbitrary individuals of the herd and remember the received signals of the measured live weight of arbitrary individuals of the herd, summarize the signals of measurements of live weight of arbitrary individuals herds and the resulting total signal is divided into a signal of the number of weighings of arbitrary individuals of the herd, forming a signal for estimating the average live weight of an individual from a herd of animals or birds, which is also a signal for estimating the mathematical expectation of live weight of an individual from a herd of animals or a bird, and a signal for estimating the average the quadratic deviation of the live weight of the individual over the herd, the magnitude of this signal being proportional to the square root of the sum of the squares of the differences of the stored signals of the measured live weight of herds and a signal for estimating the mathematical expectation of live weight of an individual according to the herd of animals or poultry divided by the difference of the signal of the number of weighings of arbitrary herds and the signal of the unit of the number of weighings of an arbitrary individual of the herd, a signal for estimating the required sample size proportional to the product of the square of the signal of the argument of the Laplace function and the square of the generated signal for estimating the average quadratic deviation of the live weight of the individual in the herd divided by the square of the given signal of the allowable In the case of a herd of error in measuring the average live weight of an individual in a herd, the generated signal for estimating the required sample size is compared with the generated signal for the number of weighings of arbitrary individuals of the herd, depending on the comparison result, or the statistical processing of the signals of the process of weighing arbitrary individuals is continued if the value of the first specified signal exceeds the value of the second specified signal or stop the statistical processing of signals of the process of weighing arbitrary individuals with equality the values of these indicated signals and when the value of the second specified signal exceeds the value of the first specified signal and under the additional condition that the signal value exceeds the number of random weighings of a given signal value of the technologically minimum amount of mandatory weighings, the obtained signals are used for the number of weighings of arbitrary individuals of the herd, a reliable estimate of the average live weight individuals according to the herd of animals or birds, estimates of the mean square deviation of live weight bi for the herd, estimates of the coefficient of variation of live weight of individuals per herd, a signal for assessing the error in measuring the average live weight of the individual for the herd to reliably inform the personnel of the agricultural premises, workshop or enterprise when carrying out managerial operator actions with technical means of providing technology for growing livestock, as well as for feeding they are grown on the corresponding measuring, controlling and setting inputs of automated technological equipment for technology management livestock.

математического ожидания М_х (см. формулу (6)), получаем окончательную формулу определения оценки требуемого объема выборки:Using the value of the estimate of the coefficient of variation V *, which is equal to the ratio of the estimate of the mean square deviation σ * to the estimate

mathematical expectation M _x (see formula (6)), we obtain the final formula for determining the estimate of the required sample size:

From the expression for the marginal error Δ _kg (absolute, i.e., in units of measurement of a random variable, in this case in kg), an estimate of the required sample size according to (18) is given:

- оценка относительной погрешности измерения средней живой массы особи по стаду, %; σ* - оценка среднего квадратического отклонения живой массы особи по стаду от оценки математического ожидания живой массы особи по стаду

, кг; n - количество взвешиваний произвольной особи поголовья животных или птицы, отн. ед.; V^* - оценка коэффициента вариации, %.Where

- assessment of the relative error in measuring the average live weight of an individual in a herd,%; σ * is the estimate of the mean square deviation of the live weight of the individual in the herd from the estimate of the mathematical expectation of live weight of the individual in the herd

kg; n is the number of weighings of any individual livestock of animals or birds, rel. units; V ^* - assessment of the coefficient of variation,%.

Dependence (19) is used when converting the corresponding signals in the method and device to obtain a reliable signal for estimating the error in measuring the average live weight of an individual in a herd.

Thus, the livestock or poultry production technologist sets the level of reliability and the permissible relative or absolute error in measuring the average live weight of an individual according to the herd of livestock of a given species and age. In other words, the required accuracy of determining this quantity is set, on the value of which the accuracy of control of the growing technology and the numerous technological processes accompanying this technology directly depends. This error corresponds to the required sample size, that is, the smallest allowable number of weighings of individuals to obtain results with a given reliability. As soon as the number of random time weighings of random single individuals becomes equal and exceeds the calculated value of the required sample size, reliable information about the average live weight of the individual for a herd of animals or birds appears.

Therefore, only a continuous, real-time, high-precision automated assessment of the average herd of live weight of an animal or bird with a discrete time random selective weighing of individual individuals of the herd during the technology of growing herds of animals or poultry makes it possible to find profitable trade-offs between feed costs and live weight gain when managing livestock production. livestock. And also between the energy costs for heating, for other technological processes and the estimated losses resulting in livestock productivity in their price terms. In this case, statistical processing of the measured and calculated signals about the live weight of the individual herd is necessary.

(For the lack of additional space in this description of the invention, in essence and due to the cumbersomeness of the additional description of fairly well-known and generally traditional actions and technical means of the operation control unit of the device 36, a detailed description of its composition and internal and external communications in the framework of this invention is of significant importance it does not, therefore, it will unreasonably overload the description of the present invention and therefore it is considered redundant and is not given in accordance with this statement); 37 - a unit for generating a total signal of the number of weighings of arbitrary individuals of the herd on several electronic scales in various local areas of the production premises or in local livestock habitats; 38 is a block for generating the total signal of the measured live weight of arbitrary individuals of the herd on several electronic scales in various local zones of the industrial premises or in local livestock habitats.

The method is as follows. An individual of a herd of livestock during normally growing technological processes of growing technology enters a load-receiving platform of electronic scales. A live mass signal of a random individual is generated. By this signal as a whole it is already possible, but with a very large approximation (with a large error), to judge the average live weight of an individual over the entire herd of livestock: for an accurate assessment, it is necessary to weigh all individuals of the herd. However, this is technologically impossible due to excessive livestock losses as a result of stressful situations associated with the intervention of personnel, or special additional equipment, in the habitat of animals or birds. Also high are operational (labor, energy, deductions for capital investments, etc.) and capital costs. Therefore, the measured, generated, compared and other signals (material objects of informational characteristics of processes) in the course of material actions by the method are subjected to mathematical statistical processing by other corresponding generated signals. Discrete in time, at the moment of approaching the weighing platform of the scales, random selective weighing of an arbitrary individual of the herd during the technology of growing the herd of animals or poultry is carried out, a signal of the technologically minimal amount of required weighings is set. According to the regulatory documents of broiler poultry farming, the number of weighed birds in the sample from the entire number of thousands of poultry premises is one hundred broilers. The signal of the largest permissible error in measuring the average live weight of an individual from a herd of animals or poultry is set, the signal of the confidence probability of a signal of estimating the average of a live weight of an animal or bird falling into the confidence interval of signals of random selective weighing of an arbitrary individual of a herd is given. Depending on this signal of confidence probability, numerically equal to the area under the curve of the normal Gaussian distribution, limited by the confidence interval of the argument, by calculating or retrieving from the memory of the appropriate technical means the stored data in accordance with the Laplace function table, the Laplace function argument signal is generated. The fact signal of the individual placement event on the weighing platform of the scales is determined and the weighing event signal is generated, the number of weighing events of individual flocks is measured, and the signal of the number of weighings of arbitrary flocks is measured. The live weight of an arbitrary herd is measured, a signal of the measured live weight of an arbitrary herd is formed, and the received signals of the measured live weight of an arbitrary herd are stored. The measurement signals of the live weight of arbitrary individuals of the herd are summarized and the resulting total signal is divided into the signal of the number of weighings of arbitrary individuals of the herd, forming a signal for estimating the average live weight of an individual from a herd of animals or birds, which is also a signal for estimating the mathematical expectation of live weight of an individual from a herd of animals or birds. A signal is generated for estimating the average quadratic deviation of the live weight of the individual over the herd, the magnitude of this signal being proportional to the square root of the sum of the squares of the differences of the stored signals of the measured live weight of arbitrary individuals of the herd and the signal for estimating the mathematical expectation of live weight of the individual over the herd of animals or birds, and inversely proportional to the signal difference the number of weighings of arbitrary individuals of the herd and the signal unit of the number of weighings of an arbitrary individual of the herd. Then a signal is generated for estimating the coefficient of variation of live weight of individuals in the herd, proportional to the ratio of the signal for estimating the mean square deviation of live weight of the individual in the herd to a signal for evaluating the mathematical expectation of live weight of the individual in the herd, multiplied by a hundred percent. A signal is generated for estimating the required sample size, proportional to the product of the squared signal of the argument of the Laplace function and the square of the generated signal for estimating the mean square deviation of the live weight of the individual by the herd divided by the square of the given signal of the permissible selective error in measuring the average live weight of the individual by the herd. The generated signal for estimating the required sample size is compared with the generated signal for the number of weighings of arbitrary herds. Depending on the result of the comparison, either the statistical processing of the signals of the process of weighing arbitrary individuals is continued when the value of the first specified signal exceeds the value of the second specified signal. Or, the statistical processing of signals from the process of weighing arbitrary individuals is stopped when the values of these indicated signals are equal and when the value of the second specified signal exceeds the value of the first specified signal and under the additional condition of the value of the signal and the number of random weighings exceeding the value of the given signal, the technologically minimum amount of mandatory weighings. The last action is performed under the additional condition that the signal value exceeds the number of random weighings of the value of the given signal of the technologically minimum amount of mandatory weighings. The obtained signals are used to estimate the average live weight of an individual for a herd of animals or poultry, to estimate the average quadratic deviation of an individual's live weight for a herd, to assess the coefficient of variation of live weight of an individual by a herd, a given signal to estimate the error in measuring the average live weight of an individual by a herd to reliably inform agricultural staff , workshop or enterprise. This is necessary when carrying out managerial operator actions with technical means to ensure livestock cultivation technology, as well as to supply these signals to the corresponding measuring, controlling and setting inputs of automated technological equipment for managing livestock cultivation technology.

An additional condition for achieving or exceeding the minimum number of weighings specified by the technology has a simple explanation. Let the first two random weighings give the same result. This means that, in all, only two experiments immediately obtained an estimate of the mathematical expectation of the average live weight of an individual for a herd of livestock. In this case, both the variance (power) of the deviation of the estimate of a random value of live weight from the estimate of its average estimate value (from the estimate of mathematical expectation), and the mean square deviation of the estimate of a random value of live weight from the estimate of its average estimate value (from the estimate of mathematical expectation) are equal to zero . Then the coefficient of variation and the value of the signal of the required sample size depending on this coefficient of variation are also equal to zero. The obtained signal value of the required sample size is formally equal to zero. Then it would seem that you could immediately stop the process of selective weighing without even starting to do it. However, this conclusion is fundamentally wrong. Continuation of the weighings and their subsequent results will show that a reliable signal for estimating the required sample size is associated both with the magnitude of the signal for estimating the standard deviation and with the magnitude of the signal for estimating the error of selective weighing. Therefore, the task on the technology of the minimum number of mandatory weighings has a deep and theoretical and practical meaning.

control unit of the device.

The device operates as follows. Scales with a loading platform and electronic output (electronic scales) 1 give a stable signal of live weight of a random individual of a herd of animals or birds, weighed randomly on the loading platform. From the output of the third driver of the signal of the number of weighings of an arbitrary individual of the herd (can be used: sawtooth generator, sci-fron, a line of triggers, a pulse counter, etc.) (third former) 7, the signal receives the number of weighings of an arbitrary individual of the herd.

When comparing the corresponding signals in the first scheme for comparing the generated signal for estimating the required sample size with the generated signal for the number of weighings of arbitrary individuals of the herd 31 and in the second scheme for comparing the signal for the number of random weighings with the given signal, the technologically minimum amount of mandatory weighings at their outputs appears at some points in time and then the signals act that control the moment of start and then the time of reliable informing the personnel about the parameters of the charge ivaemogo livestock.

Figure 4 shows additional elements of the functional diagram of the device according to the method with several electronic scales installed in the production room or in the living area of the livestock scheme of the device for implementing the method.

The additional device according to the method contains two or more electronic scales installed in the production room or in the livestock area (the elements of three electronic scales 1 ₁ , 1 ₂ , 1 ₃ are shown) and the corresponding number of second shapers 6 and third shapers 7 (three second shapers 6 _1, 6 _2, 6 ₃ and three third shaper July ₁ 7 ₂ 7 ₃₎ meters bodyweight signal unit specimens Step 8 _1, 8 _2, 8 _{3, the} fourth formers signals measured bodyweight arbitrary individuals herd in different local areas ter Ithor industrial premises or in local zones of livestock habitat (Fourth formers) 9 ₁ and 9 _2, 9 _3, where a block operation device 36 controls, providing a device by the method of various actions: summation signals amounts random weighings arbitrary individuals livestock in different zones, the accumulation of , storing and summing up random signals of the weighted live weight of arbitrary individuals of the herd for all local habitats controlled by electronic scales, in an additional device It superimposes the signals of the weighings and live weight signals from different electronic scales from different habitat zones at the same time that arrive at the device, makes their respective time separation and their corresponding time delays in relation to each other, and the outputs of the third shaper 7 ₁ , 7 ₂ 7 _{3 are} connected to the corresponding inputs of the additional signal additionally introduced into the device of the total signal generation unit of the number of weighings of arbitrary individuals of the herd on several electronic scales in different local local areas of the premises or in local areas of livestock 37, outputs of electronic weights 1 ₁ , 1 ₂ , 1 ₃ or outputs of signal conditioners of measured live weight of arbitrary individuals of the herd in different local areas of the premises or in local areas of livestock (fourth formers) 9 ₁ and 9 _2, 9 ₃ is connected to the corresponding inputs additionally introduced into the device forming the sum signal unit measured bodyweight arbitrary individuals herd at not waged on electronic scales in different local areas of the territory of the production area or in the local areas of habitat population 38.

The device operates as follows. Increasing the number of weights is not only aimed at increasing the number of weighings. Scales in the amount of more than one piece can be placed in the production room or on the habitat of the weighed livestock in such a way that the heterogeneity of the live weight of the herds will be additionally taken into account: after all, in different zones of the habitat of the livestock, the conditions can vary quite significantly. This is the presence of drafts, and local (local) thermal and other radiation from the placed equipment, the different distance of the feeding line from its beginning to the place of feeding of the herds, etc. The presence of several correctly selected places of the technologist equipped with scales significantly increases the reliability of assessing the live weight of an individual throughout the herd. The assessment of the uniformity of the herd of the livestock by the value of the coefficient of variation becomes more complete. At the same time, the list of functions (actions) of the operation control unit of the device 36 is expanded, which ensures that the main device provides timely summation of the signals of the quantities of random weighings of arbitrary livestock in different zones, accumulation, storage and corresponding summation of random signals of the weighted live weight of arbitrary individuals of the herd for all controlled electronic scales local habitats. Block 36 also eliminates the overlapping of the signals of the quantities of weighing and the signals of live weight from the different weights at the same time, and makes their respective time separation and their corresponding time delays. (For the lack of additional space in this description of the invention, in essence and due to the cumbersomeness of the additional description of fairly well-known and generally traditional actions and technical means of the operation control unit of the device 36, a detailed description of its composition and internal and external communications in the framework of this invention is of significant importance it does not, therefore, it will unreasonably overload the description of the present invention and therefore it is considered redundant and is not given in accordance with this statement).
