The results of studies of the productivity and interior of young cattle of the Charolais breed fattened in CJSC Firm of Agrocomplex named after N.I. Tkachev, Vyselkovsky district, Krasnodar Territory. With a live weight before slaughter of 560.4 ± 16.7 kg, carcasses with a slaughter yield of 68.0% were distinguished by high rates of meat: the yield of boneless beef for baby food was 81.0%. At the age of 18 months animals had the highest content of total protein in the blood serum. In comparison with 12-month-old, bulls of 18 months old sowed higher live weight values, as well as higher albumin fraction indicators. The same trend was observed for the protein index (Albumin/Globulin - A/G) - an indicator of the state of protein metabolism (0.72 - at 12 months and 1.23 - at 18 months). An increase of 3.8% in the amount of lysozyme in the blood serum of bulls at the age of 18 months was established. compared to 12 months. (p

The article presents the results of a scientific and economic experiment to assess the meat productivity of Kazakh white-headed bulls in the conditions of Southern Russia. he fattening of the bulls lasted until the age of 15 months. During the fattening period, the animals of the experimental group surpassed the peers of the control group according to indicators of meat productivity. By changing the conditions of feeding and keeping calves at different age stages of their development, a person forms in them those vital functions, organs and tissues that most contribute to ultimately obtaining the greatest amount of high quality milk and meat productivity in adulthood. The paper presents the results of growing bulls of the Kazakh white-headed breed up to 15 months of age using the probiotic Prolaxim-V feed additive to obtain meat raw materials that meet the requirements for the production of food for children of early age. The use of a probiotic feed additive made it possible to increase the live weight by the end of the experiment by 8.65% (P < 0.01), the slaughter yield by 1.95 absolute percent, and reduce the incidence rate of the gastrointestinal tract.

It was assumed that the industry of beef cattle breeding being created in the Krasnodar Territory would meet the needs of the population in beef. Due to the fact that there are not enough beef cattle, dairy bulls are raised and fattened. Positive results are obtained in the case when, along with an increase in the number of the fattened livestock of animals, their intensive rearing and feeding is introduced. In our studies, with intensive rearing and fattening of the Holstein and Black-and-White bull calves, for the entire 14-month period of growing and fattening, average daily gains were obtained at the level of 1200 g, and the gross weight gain was more than 500 kg. According to the results of the slaughter of experimental bulls at the age of 14 months, we found that the Holstein bulls reliably exceeded the black-and-white bulls of the same age in all the studied parameters.

In the raw material zone of baby food producers in the Krasnodar Territory, a large Ermakov farm supplies turkey to the Branch “Plant of canned meat for children Tikhoretsky JSC “Danon Russia”. According to the results of the slaughter of five-month-old turkey of two crosses, White broad-breasted and Hybrid Converter, high indicators of meat productivity were established: slaughter yield (81.2 and 85.0 %), yield of meat suitable for baby food 62 % and 65 % , the yield of white breast meat - 23 and 25 %, respectively, for the White broad-breasted and Hybrid Converter crosses. In terms of meat yield from five-month-old turkeys, the advantage of the Hybrid Converter cross has been proven. On the basis of the studies carried out, it can be concluded that the meat of the turkey of the White broad-breasted and Hybrid Converter crosses have a high biological value in terms of chemical and amino acid composition.

The research was conducted to compare bulls and castrates in relation to the morphological composition of carcasses, the yield of beef suitable for the production of baby food products, and the quality and safety of raw meat. The research was based on the results of monitoring the safety of the environment, feed, and meat raw materials during the growing and fattening of steers with a meat productivity direction. The pre-slaughter weight and the yield of lean beef of 16-month-old Hereford bull-calves are higher in comparison with castrated animals of the same age, by 6.4 and 1 %, respectively. The muscle tissue of castrates contained 11.5 % of fat, and bulls 9.7 %. The protein content in the longest muscle of bulls was 19.8 %, and in castrates-17.0. The amount of fat beef that is not suitable for baby food is higher in castrate carcasses by 4.7 % compared to bull calves. A high protein quality index of the longest muscle of bulls (6.5) indicates a higher biological value of beef compared to meat from castrates (4.1). In terms of the content of residual amounts of pesticides, toxic elements, and antibiotics, the meat of castrates and bulls of the Hereford breed had no significant differences.

The research was carried out on the farms of the raw material zone of the Branch "Tikhoretsky Canned Meat Plant" of DANON RUSSIA JSC in two districts of the Krasnodar Territory. Experimental data on the productivity of bull-calves of dairy-meat black-and-white breed and its cross-breed with bulls of Kalmyk beef breed. In the "Rubin" farm of the Goryacheklyuchevsky district, the productivity of beef cattle of the Charolais breed was studied. In the study of raw meat for baby food, a comparative assessment of the quality and food safety of beef from black-and-white bulls; cross between black-and-white and Kalmyk breeds; Charolais breed was carried out. In terms of protein quality indicator (6.5), beef from Charolais bulls exceeded the rest (6.16 and 5.8). The Charolais breed has the best protein composition (19.8 g / kg of lysine, the limiting amino acid for the child's body). In terms of safety indicators, taking into account the maximum permissible levels of residual amounts of pesticides, toxic elements, antibiotics, meat raw materials from black-and-white bulls and a cross with the Kalmyk breed met the requirements of the interstate standard for raw materials for baby food.

Subjects of the research: soils, pasture and cultivated plants, vegetable raw materials, prepared feed of the raw material zone of the Branch of the Tikhoretsky Children's Meat Canning Plant of DANON-RUSSIA JSC. The quantitative content of mobile forms of heavy metals in soils under the main feed crops and their accumulation in finished feeds was determined. The a soil with a high humus content cover in the area of the surveyed farms is mainly represented by carbonate weakly humus heavy-duty “chernozem”, which occupies 82.5 % of all land. Fodder raw materials in the autumn-winter season 2019-2020 is safe in quantitative content regulated by standards of elements of heavy metals. Their contents were established: mercury ≤ 0.01 mg / kg, cadmium ≤ 0.2 mg / kg, lead ≤ 2.0 mg / kg and arsenic ≤ 0.5 mg / kg. However, there was an insignificant (1-2%) increase in the zinc content in the silage from the green mass of corn and haylage from the green mass of alfalfa. It was established that the remains of the prohibited pesticides are in trace amounts or practically absent in the feed of the raw material zone. The monitoring results will be used in farms - suppliers of beef for the production of baby food - canned meat and meat and vegetable.
