Description

A method of growing repair young egg chickens relates to poultry farming, in particular to feeding and raising chickens.

A known method of growing broiler chickens using the probiotic "Subtilis", in which the probiotic with water is soldered according to the scheme: the first 5 days - through vacuum drinkers in a dose of 1 ml per 50 heads, and then, starting from 28 days, for 3 days in the same dose through a mediator (dispenser) connected to the nipple system of watering (V. Filonenko, I. Saleeva, G. Kulakov, V. Mikhailov. The probiotic "Subtilis" is useful for broiler chickens. M: Poultry farming, No. 2 , 2004, p.21-22).

The disadvantages of this method are the insufficiently high safety of chickens, as the safety is increased by 0.7% compared with the control group, and a slight decrease in the mortality of chickens.

The technical result is the expansion of the range of funds and a method of growing repair young stock of egg chickens, increasing the productivity and preservation of the number of birds.

The technical result, in contrast to the prototype, is achieved due to the fact that the method of growing repair young egg chickens includes feeding the main diet with a probiotic, moreover, the working solution of the fermented milk product "Narine" with an acidity of 110-120 ° T is introduced by spraying into the main diet of chickens from 6 days age in the amount of 0.1 ml / goal. 1 time per day for 10 days, then arrange a break of 10 days, then again injected at 0.2 ml / goal. 1 time per day for 10 days, moreover, before the introduction of the fermented milk product “Narine” into the main diet, it is preliminarily diluted in a 0.5% glucose solution in a ratio of 1:15, respectively.

One of the main problems weighing on the poultry industry is the high cost of feed. Moreover, often purchased feeds are of poor quality: toxic, weed, seeded with mycotoxins. All this reduces the body's resistance and increases the risk of dysbiosis.

Currently, a serious problem for the poultry industry is the production of environmentally friendly and safe food products. This problem can be solved by adding probiotics to the main feed. Probiotic therapy as an alternative to antibiotics can reduce the incidence of young gastrointestinal diseases and the risk of food contamination by foodborne infections.

Probiotic drugs - a new generation of drugs containing live beneficial bacteria that prevent colonization of pathogenic microflora and maintain normal intestinal microbiocenosis. According to the mechanism of action, probiotics differ from antibiotics, are harmless at multiple dosages, and are effective in feed toxicosis. Probiotics stimulate the formation of vitamins and enzymes in the body.

In literature there is no information on the use of the probiotic "Narine" in poultry production. Dry bacterial sourdough “Narine” is a lyophilized culture of acidophilic sour-milk bacteria, strain 317/402, and is commercially available in 5-dose vials.

The studies were conducted at the Zarya Poultry Farm on the stock of repair young stock of hens of the Rodonit cross. For this purpose, three groups were formed: control - 5005 goals, 1 experimental - 5005 goals, 2 experimental - 5005 goals. The experimental design is presented in table 1.

The birds of all groups were kept in the same house in KBU-3 cell batteries, observing technological standards. They fed full feed in accordance with the norms of VNITIP (2003).

The first, control, group received the main diet (OR), for chickens of the first and second experimental groups, the working solution of the Narine fermented milk product was introduced to the main diet. According to statistics, the most difficult periods in the life of chickens are the first 5 days, the 20th and 35-40th days. Given these periods, the “Narine” feeding scheme was developed (table 3).

Table 3 The scheme of introducing a working solution of fermented milk product "Narine" in the diet of chickens of the experimental groups Stages of Administration Age of administration The dose of the additive, ml / goal. Frequency of administration The first experimental group First period of administration from 6 to 15 day 0.1 Once a day Break from 16 to 25 day - - The second period of administration from 26 to 35 day 0.2 Once a day The second experimental group First period of administration from 12 to 21 days 0.1 Once a day Break from 22 to 31 days - - The second period of administration from 32 to 41 days 0.2 Once a day

From table 3 it is seen that in the 1st experimental group, the working solution of the Narine lactic acid product was started from 6 days of age, in the second experimental group - from 12 days old at 0.1 ml / goal. 1 time per day for 10 days, then a break was arranged in both experimental groups for 10 days, then there was a second period of introducing a working solution of lactic acid product “Narine” into the main diet at 0.2 ml / goal. Once a day for 10 days.

To control the growth and development of young animals, control weighing was carried out using Kenwood waymaster hand weights with a specific gravity of 5 kg and a weighing accuracy of 5 g. The sample during weighing was 50 goals. The growth rate can be judged both by the absolute value of the growth, and by the relative growth.

The working solution of the Narine fermented milk product was fed by spraying the feed using the Spray apparatus. As a Narine diluent, a 5% glucose solution was used in a ratio of 1:15, respectively, which facilitates the spraying of the drug into feed, in addition, glucose is an additional easily digestible energy source.

Preparation of the Narine product consists of several stages: preparation of the uterine culture of Narine, then the preparation of a working solution of the fermented milk product Narine.

Uterine Uterine Culture is prepared using whole or reconstituted milk. In 1 liter of milk add 2 bottles of 5 doses of dry lyophilized culture "Narine", mix thoroughly and place in a thermostat for 15 hours at a temperature of 38-40 ° C.

After the set time has elapsed and a clot forms in the uterine culture, it is placed in the refrigerator for 2 hours, where the final maturation occurs. In the future, if necessary, it is possible to use in certain parts the obtained uterine culture of Narine for the preparation of a working solution of the fermented milk product Narine.

The working solution of the Narine fermented milk product, as well as the uterine culture, is prepared in whole or reconstituted milk. 2 tablespoons (30 ml) of the uterine culture are added to milk and placed in a thermostat for 5 hours at a temperature of 38-40 ° С. After the expiration of the set time, the resulting product is put in the refrigerator for 2 hours, where the final ripening to the acidity of the finished product 110-120 ° T. This technology, i.e. preparation of the uterine culture and the working solution of the Narine fermented milk product, allows you to multiply, increase the number of beneficial fermented milk bacteria.

It is known that biochemical processes depend mainly on pH and the optimal temperature in the digestive system. All warm-blooded animals have microbial populations that populate the digestive tract shortly after birth. Strains of beneficial microorganisms produce a large amount of lactic acid from simple carbohydrates and can exist with high acidity, which creates a barrier to pathogenic microflora. It is also known that during the first weeks of growing in chickens, thermoregulation and digestion systems are still imperfect, therefore a very high incidence and mortality rate. From this it follows that it is important to pay increased attention to the maintenance and proper feeding of chickens. The research results are shown in table 4.

So, as a result of the introduction of the working solution of the Narine fermented milk product into the diet of young animals, an increase in the bird's viability was observed, which affected its safety (table 4).

From this table it can be seen that “Narine” has a positive effect on the viability of chickens. The number of deaths in the first experimental group compared with the group of control chickens decreased by 1.32%, and in the second experimental group by 0.88%, respectively, and the safety increased.

You should pay attention to a significant reduction in rejection due to vitamin deficiency - by 66.7% in the first experimental group and by 46.7% in the second experimental group. The obtained indicators indicate the vitamin synthesizing activity of Narine. Thanks to the use of the working solution of the Narine fermented milk product, the business yield of chickens increased by 1.58 and 1.08%, respectively. Thus, in birds taking the working solution of the Narine fermented milk product, resistance to various stress factors increased.

One of the indicators characterizing the health of the bird, as well as the normal growth and development of young animals, is live weight. Chickens, especially in the conditions of cell keeping, grow very intensively during the first two months of life, in the future the growth rate decreases significantly. During the first month of life, the weight of the chicken increases by 7-8 times. The weighing data are presented in table 5.

From the data of table 5 it is seen that the indicators of live weight in the experimental groups by the end of the first growing period significantly exceed the indicators of live weight in the control group.

So, the live weight of chickens in the first experimental group is 11.3% higher than the same indicator in the control group. In the second experimental group, the live weight compared to the first experimental group is lower by 30 g or 4.5%. From the data obtained, it can be concluded that the fermented milk product “Narine” has a positive effect on the growth of the body of repair young egg chickens, and the beginning of feeding it at 6 days of age gives a higher increase in live weight than the beginning of feeding at 12 days of age. The difference between the experimental and control groups is highly reliable at P> 0.999.

To control the growth and development of young animals, the average daily growth and growth rate of the experimental bird was determined, the results are presented in table 6.

From the data of table 6 it is seen that the average daily increase in the experimental groups is higher than in the control. In the first experimental group, the average daily gain for the entire growing period exceeds the same indicator in the control group by 1.2 g or 12.5%, and the average daily gain in the second experimental group is higher by 0.7 g or 7.3%. The growth rate in the 1st experimental group for the study period was 2.3%, in the second experimental group 1.3% higher than in the control, and 1.0% higher than in the 2nd experimental group. From the data presented, it can be concluded that the working solution of the fermented milk product “Narine” has a growth-promoting effect; better results were obtained at an earlier start of feeding, i.e. from 6 days of age. This is explained by the fact that the fermented milk product “Narine” has a beneficial effect on the development of normal intestinal microflora, and is also a source of B vitamins, macro- and microelements. The use of “Narine” in the feeding of repair young egg chickens in the first month of life favorably affects further periods of growing, that is, the working solution of the fermented milk product “Narine” has a prolonged effect.

To determine the feasibility of using the Narine fermented milk product, a calculation of economic efficiency was carried out (table 7).

During the period of research on the number of chickens of each experimental group, 4 kg of milk powder and 25 bottles of the freeze-dried additive “Narine” were consumed. The cost of 1 kg of milk powder is 63 rubles, 1 bottle is 1.5 rubles. The cost of the fed supplement was 289.5 rubles.

According to the accounting data of the Zarya poultry farm, the prime cost of 1 kg of live weight gain without the introduction of a working solution of the Narine fermented milk product is 3770 rubles.

The total cost of the control group 98397 rubles. (26.1 c × 3770 rubles).

The costs in the experimental groups 98,686.5 rubles. (98397 rub. + 289.5 rub.).

The cost of 1 centner growth in the first experimental group is 3312 rubles. (98,686.5 rubles: 29.8 c), in the second experimental group 3499 rubles. (98686.5: 28.2).

The data in table 7 indicate the high economic efficiency of the use of the product "Narine", which increases the productivity and viability of chickens. With insignificant additional costs for a probiotic, the cost of 1 centner of growth in chickens of the first experimental group is lower by 12.1%, chickens of the second experimental group - by 7.2% compared with the control. It is more expedient to feed the working solution of the Narine fermented milk product from 6 days of age, which will save 0.47 centners of unit on each centner of growth and reduce the cost of 1 centner growth by 458 rubles. or 12.1%, and the cost of 1 head repair chicken 1%.

The dairy product “Narine” is an affordable and cheap biologically active feed additive and can be used at any poultry enterprise according to the developed method. Thanks to the preparation of the first Narine uterine culture, and then the working solution of the Narine fermented milk product, live acidophilic bacteria with a wide spectrum of activity multiply, including for the treatment of dysbacteriosis in birds, and this also saves the Narine fermented milk product ".
