Description

The present invention relates to agricultural production, in particular to poultry farming, and can be used in poultry farms, farms with various technologies for keeping poultry, as well as in farms and private farmsteads.

Known compound feed for laying hens PK-1, described in the RUBIKOM prospectus of the LLP of the Rubikom enterprise in Pavlodar, published on the website www.rubicom.kz 01/25/2011 Compound feed contains, wt.%: Wheat 42.6; barley 20.0; corn 5.0; bran 10.0; sunflower meal 7.0; soybean meal 4.0; fish flour 1.0: meat and bone meal 1.3; tricalcium phosphate 1.4; premix P1-2 1.0; salts of 0.3; lysine 0.1; limestone flour 6.3.

However, even using such a full-feed compound feed, the egg productivity of the bird remains not high enough.

Known feed additive described in the patent of Russia for invention No. 2060686, published 05.27.1996, the composition of the feed for farm animals and poultry includes feed as the main ration and as an additive drain water - waste production of microvit A, which is a substitute for standard vitamin A. The additive is introduced into the diet in quantities that ensure the need for the specified vitamin for a given species of animals and birds. In this case, the increase in live weight of broiler chickens is increased by 73.0%, gobies - by 19.5%, egg production of laying hens - by 8.9%.

The disadvantage of this method of feeding is that the waste products of microvit A can be found only at the place of production of vitamin A, therefore this method cannot be widely used.

There is a known method of feeding and food for chickens, described in Russian patent No. 2185743, published July 27, 2002. The invention is intended for use in feed production for feeding laying hens. The feeding method includes introducing into the basic feed α-linolenic acid in an amount of 0.5-15 wt.% By weight of the feed and an antioxidant in an amount of from 0.1 to 0.6 wt.% Of the weight of the feed. Flaxseed oil is used as a source of linolenic acid. Eggs of improved taste with reduced cholesterol are obtained.

The disadvantage of this chicken feed is that they use linseed oil as α-linolenic acid, which is quite expensive to manufacture and sell, and chemically synthesized substances are used as antioxidants, which does not always suit buyers.

Known feed for poultry described in Russian patent for invention No. 23003878, published January 27, 2007. Feed for poultry includes balanced compound feeds with the addition of sunflower oil as the main diet and additionally contains palm fat CAF 100, which partially replaces rations of sunflower oil for laying hens throughout the entire productive period of egg production and broilers aged 1-4 weeks in the ratio - dry palm fat CAF 100 and sunflower oil 1: 1, and for broilers aged 5-7 weeks in a ratio of 1.75: 1, respectively.

The productivity of poultry is increased, as well as the quality of eggs and meat, including the desired coloring of broiler carcasses and egg yolk, the optimal level of linoleic acid is maintained due to the introduction of CAF 100 into the feed.

The disadvantage of this method of feeding is that dry palm fat CAF 100 is not always available, so this method will not find wide application.

A known method of increasing the egg productivity of laying hens is described in the Russian patent for invention No. 2370099, published on 10/20/2009. The invention relates to feeding poultry. A method of increasing the egg productivity of laying hens includes feeding mixed feed containing wheat, barley, sunflower meal, soybean meal, fish meal, vegetable oil, corn, bran, limestone, monocalcium phosphate premix, in addition to the main period from 14 to 16 weeks of life the diet is fed cadmium sulfate at a dosage of 40 mg per kg of feed.

The disadvantage of this method is that cadmium sulfate is added to the feed - a chemical substance with the formula CdSO ₄ , which includes cadmium, which is a heavy metal harmful to human health. The negative attitude of the vast majority of the population to products obtained using heavy metals should be taken into account.

Known feed for young chickens is described in Russian patent No. 2383208, published March 10, 2010. The feed is intended for agricultural poultry of egg production. The feed for young egg-laying hens includes feed from wheat, barley, sunflower meal, soybean meal, fish meal, vegetable fat, corn, bran, chalk, salt, premix and additionally includes a complex of minerals consisting of zinc sulfate, sodium selenite and iodide potassium.

The disadvantage of this feed for young chickens is that the complex of minerals consists of zinc sulfate, sodium selenite and potassium iodide - chemically synthesized substances, which does not always suit buyers. In addition, the egg productivity of laying hens is low.

The closest method of feeding laying hens, selected as a prototype, is the method of feeding compound feed for laying hens - option No. 2, described in the book "Scientific principles of feeding of agricultural poultry", the authors V. I. Fisinin, I. A. Egorov, T.M.Okolelova, Sh.A. Imangulov, - Sergiev Posad, 2008, - p. 82, consisting of, wt.%: Feed wheat - 54.0; unbroken barley - 14.20; sunflower meal (joint venture 34%, SCl 17%) - 7.0; soybean meal (SP 42%, ur 0.15%) - 5.23; meat and bone meal (joint venture 36%) - 2.0; fishmeal (joint venture 62%) - 4.46, sunflower oil - 2.5; lysine (monochlorohydrate) - 0.01; methionine - 0.13; table salt - 0.13; defluorinated phosphate (Ca 30%, P 18%) - 0.90; limestone - 8.44; premix - 1.0.

The disadvantage of this method of feeding is that when this feed is used in feeding, low egg productivity of laying hens is obtained.

The objective of the proposed method of feeding laying hens is to increase the egg productivity (egg production) of laying hens by changing the percentage of compound feed of option No. 2 described in the book "The Scientific Basis of Feeding Poultry", the authors V. I. Fisinin, I. A. Egorov, T.M.Okolelova, Sh.A. Imangulov. - Sergiev Posad, 2008, - p.82, and the introduction of ground barley grain with brown-black and / or black (hereinafter dark-colored) color of the grain containing proanthocyanidins / anthocyanidins, which are active biological antioxidants that affect egg productivity .

The technical result is achieved by the fact that in the method of feeding laying hens, including as the main ration for feeding compound feed, consisting of feed wheat - 54.0; unbroken barley - 14.20; sunflower meal (SP 34%, SC 17%) - 7.0; meal of soybean (SP 42%, ur 0.15%) - 5.23; meat and bone meal (joint venture 36%) - 2.0; fish meal (SP 62%) - 4.46, sunflower oil - 2.5; lysine (monochlorohydrate) - 0.01; methionine - 0.13; common salt - 0.13; defluorinated phosphate (Ca 30%, P 18%) - 0.90; limestone - 8.44, premix - 1.0, according to the invention, the main ration of feeding with compound feed is supplemented with an additive of plant origin, which is used ground grain of dark-colored barley, in the following ratio of components, wt.%: 15% ground grain of dark-colored barley, basic feed feeding ration - the rest, laying birds are fed three times a day with an interval of 5-6 hours.

Due to the fact that in the method of feeding laying hens, the main diet is supplemented with an additive of plant origin, which is used as ground grain of dark-colored barley, in the following ratio of components, wt.%: 15% ground grain of dark-colored barley, mixed fodder of the main diet is the rest, laying birds are fed three times a day with an interval of 5-6 hours, the egg productivity (egg production) of laying birds is increased.

The inventive method of feeding laying birds has a novelty in comparison with the prototype, differs from it by the above characteristics and ensures the achievement of the technical result perceived by the applicant.

The set of essential features of the proposed method for feeding laying hens does not follow explicitly from the studied prior art, i.e. meets the criteria of "novelty" and "inventive step".

The inventive method of feeding laying birds will find wide application, i.e. is industrially applicable.

The essence of the invention is explained.

At present, barley with straw yellow color of grain is used in all compound feeds of the Russian Federation, since according to the State Commission of the Russian Federation “Characteristics of Breeding Achievements: 2011”, only varieties with straw yellow color of grain are used for barley production - 160 varieties of spring and 27 varieties of winter barley related to such botanical varieties as nutans, medicum, submedicum, erectum, ricotense, parallelum, pallidum - membranous barley and nudum, celesta - barley barley. Varieties of barley with a different color of grain are not listed in the State Register and are absent in the agricultural production of the Russian Federation (http://www.gossort.com/xrcts/xrct 30.html, http: //www.gossort.eom/xrcts/xrct_29.html # 9553947).

According to the literary source (Cultural Flora of the USSR: Vol. II, Part 2. Barley / M.V. Lukyanova, A.Ya. Trofimovskaya, G.N. Gudkova, etc. - L .: Agropromizdat, Leningrad. Department, 1990) in the world collection of the All-Russian Institute of Plant Industry (VIR) there are forms of barley of botanical varieties with grain painted in black and brown-black. This color of the grain is due to the presence of pigments in the seed coat (“test”), as well as in the aleuron layer and in the fruit coat of the grain (p.181-182; 224). In the indicated source, these varieties are described on pages 28-39 under No. 3-6, 19, 22, 32-35, 37, 43, 47; on p. 45-57 under no. 60, 61, 74, 79, 94, 106, on p. 63-79 under no. 119, 121, 122, 125-127,133, 145, 146, 148-152, 156, 160, 164, 165, 176, p.83-89 under No. 186, 187,189, 194, 200, 201, 205, 212. The vast majority of such barley is found in the form of impurities in the crops of Ethiopia, less often in the countries of the Front and South East Asia. These are rare endemics, in the spectrum of the color of the grain of which are brown-black and black. In addition, various colors of the spike and caryopsis are described in the book by A. A. Gryaznov “Key to intraspecific taxa of cultivated (sowing) barley, Kostanay, 2007 - pp. 15-17, 20-23, 25-67.

According to these sources, 24 botanical varieties of two-row and 22 varieties of multi-row barley possess dark-colored grain in world diversity.

In the USSR and in Russia, collection samples with similar grain colors were used at different times by breeders in barley breeding programs. A production-significant variety of this crop with the indicated grain color was obtained by the breeder Anatoly Aleksandrovich Gryaznov in the conditions of the Skif Scientific and Production Peasant Farm of the Varna region of the Chelyabinsk Region from 2006-2010. (see the conclusion of the head of NPKH “Skif” Chirkov N.M.).

The resulting breeding form of barley with dark-colored grain has a number of advantages and allows you to get a practical effect from use in animal husbandry. According to the literary source (Cultural Flora of the USSR. / Lukyanova M.V., Trofimovskaya A.Ya., Gudkova G.N. et al. Volume II. Part 2. Barley - L .: IN “Agropromizdat”; Leningrad. 1990. - p. 182, 352) in barley, the ant genes control the biosynthesis of catechins and proanthocyanidins (catechin dimers) in the weevil and anthocyanins (anthocyanidin glycosides) in the plant. These substances largely determine the color of the pigments in the seed coat, the aleuron layer, the fruit coat and flowering scales.

According to the article by A. I. Rybalka, M. M. Kopus, D. P. Dontsov, “Modern Directions for Improving the Quality of Barley Grain”, published in the Agrarian Bulletin of the South-East, No. 3, - 2009, p. 18-21, during processing barley grain retains all its beneficial components, including proanthocyanidins, which are active antioxidants.

Anthocyanin pigments belong to the class of flavonoids and are a large group of natural colored compounds from red to blue (V.L. Kretovich. Fundamentals of plant biochemistry / Ed. 5th corrected and supplemented // Vysshaya Shkola Publishing House, M., 1971. - 147-151 pp .; Report of the accredited testing analytical center of the N.N. Vorozhtsov Novosibirsk Institute of Organic Chemistry, Siberian Branch of the Russian Academy of Sciences, 5 pp.). In plant materials, these compounds are in the form of free anthocyanidins (flavilium cations), but more often they are present in the form of anthocyanidin glycosides. In addition, the plants contain leukoanthocyanidins and proanthocyanidins, belonging to the group of flavonoids that are colorless. When heated with acids (acid catalysis conditions), the compounds of leukoanthocyanidins and proanthocyanidins turn into anthocyanidins with a characteristic red to blue color and an absorption band in the visible region with λ _max 520-540 nm, thus, they can be considered as sources of anthocyanidins in plants.

Hydrolysis of flour and analysis of hydrolysates for the content of anthocyanidins by separating the solution by centrifugation followed by UV spectrometry, as well as by high performance liquid chromatography carried out in the laboratory of environmental studies and chromatographic analysis (N.N. Vorozhtsov Novosibirsk Institute of Organic Chemistry), showed that the total content of anthocyanidins in the hydrolysates of dark-colored flour was: see table 1:

Table 1 Corn The content of anthocyanidins, mg / 100 g Deviation Straw yellow 4.1 ± 0.04 The control Dark colored 104.5 ± 10.0 100,4

To assess egg productivity (egg production), laying hens at the age of 45 days were selected, who received barley grain with different colors in the composition of the feed. Scientific and economic experience was carried out in the state of emergency "Cheklaukov-Kazantsevo" (Chelyabinsk). The quail of the Japanese Quail egg breed (hens) was divided into a control group and three experimental groups of 90 quails each.

Within each group, quail was kept in three cages; each cage (replicates) contained 30 animals, i.e. in the experiment with each group, there were a total of 90 goals.

The conditions of the experimental birds of all groups were identical.

The real time of the experiment is 36 days. Thus, 4 weeks of 7 days and one week of 8 days.

Quails of all groups were fed without restrictions, i.e. plenty. In order to avoid food spoilage, its distribution was carried out three times with an interval of 5-6 hours. Feeding began at 7 hours 30 minutes. Restrictions on water consumption were not allowed. In order to prevent the spread of feed, feeding troughs with curved sides were used.

No mortality was observed during the first 3 weeks. Then, over the course of 4-5 weeks, one head fell in each cell:

In the control group at the beginning of the 5th week, one layer in each repetition;

In the first group - in the third repetition on the 4th week, and in the first and second repetitions on the 5th, etc.

Therefore, tables 2, 3, 4, 5 show the state with a livestock for each week. Hence, the average number of goals is not expressed in whole numbers.

Table 2 for the control group of quail.

Table 3 for the first experimental group (O1).

Table 4 for the second experimental group (O2).

Table 5 for the third experimental group (O3).

Table 6 summarizes the data.

Since the content of each laying bird is associated with feeding, each day its content was expressed in fodder days. There are 30 laying hens in a cage, the content of this livestock per week is expressed at 210 feed days, the fifth week (8 days) is expressed at 232 feed days.

Feed consumption was taken into account as follows. At the beginning of each week, 10 kg of food was prepared for each quail cage (repetition). At the end of each day, the feeders with the rest of the feed were taken out of the cells, and in the morning they were again set up with the addition of a new portion of the feed. The consumption was calculated weekly by weighing the mass of feed at the beginning and at the end of the week (a round figure of 10 kg was taken for the convenience of calculations).

Feed intake per feed head in grams per head was determined by dividing feed consumption by the corresponding feed days and livestock.

The eggs laid were counted daily and weekly. The egg laying rates of laying hens per fodder day are obtained by dividing the sum of laid eggs by the corresponding number of fodder days.

Calculation for groups O1, O2, O3 of experiment No. 3: 1.5 kg of compound feed (15%) was taken from the feed mass of 10 kg (100%) and this compound feed was replaced by 1.5 kilograms of barley (15%). As a result, it turned out that 85% was left in the new mass of the original compound feed itself, and 15% was barley for replacement (see table 8). Hence, the content of ingredients in three groups is considered. For example, if for wheat feed value 54 is taken as 100%, then 85 of this mass is 45.90%.

It was established that the egg production of laying hens of the third experimental group in experiment No. 3 with the ratio of the main diet — compound feed of option No. 2 described in the book “Scientific basis for feeding poultry,” authors V. I. Fisinin, I. A. Egorov, T. M. Okolelova, Sh.A. Imangulov. - Sergiev Posad, 2008, - p. 82, - 85% and additives of plant origin - ground grain of dark-colored barley 15% was higher than that of the laying hens of the control, first and second groups.

Economic indicators of the use of barley with different grain colors when feeding quail hens in experiment No. 3 are presented in table 9.
