There are presented materials on the use of feed additives based on protein hydrolysates of plant origin (Abiopeptide and Abiotonic) in rabbit breeding, as well as the results of organoleptic studies and determination of safety indicators and biological value of the resulting meat. It was noted that the feed additives Abiopeptide and Abiotonik contributed to an increase in the live-weight of rabbits, which, on average, in animals of the 1st experimental group (Abiopeptide) reached - 3.35 kg, the 2nd (Abiotonic) - 3, 42 kg and in control - 3.08 kg. The analysis of the obtained results showed that the average daily increase in the liveweight of rabbits in the 1st group was 42.6 ± 5.23 g, the 2nd - 44 ± 7.44 g, and in the control - 38.2 ± 5.33 g , which by 11.5% and 15.2%, respectively, exceeded the increase in body weight of control animals. It has been established that in terms of organoleptic characteristics, the meat of rabbits of the experimental and control groups meets the requirements of good-quality meat that meets the requirements of GOST 20235.0-74 “Rabbit meat. Sampling methods. Organoleptic methods of quality assessment”. When examining the toxicity and biological value of meat, its negative effect on the growth and survival of the test culture Tetrachimena pyriformis was not established. Rabbit meat complies with the requirements of SanPiN 2.3.3.1078-01 "Hygienic requirements for the safety and nutritional value of food", p. 1.1.1, 1.1.1.1.

This article presents materials on the production test of the feed additive Abiotonik at the Zagorsk EPF poultry farm. The safety indicators of meat and macro- and microelements in the red and white muscle tissue of Smena-8 broiler chickens are also studied.

This article presents materials on the production test of feed additive based on the protein hydrolyzate Abiotoniс on calves of the Holstein breed raised in «Sovkhoz Golovkovo» in dairy farm «Kryukovo». Two groups of XNUMX calves were formed in each experimental group, the Abiotonic feed additive was soldered at a rate of XNUMX ml/kg live weight. In order to determine the effectiveness of the feed additive, we studied the indicators of the clinical status of calves and a biochemical and general blood test. As a result, the use of the Abiotonic feed additive at a dose of XNUMX ml/kg of calf live weight has been established that it does not negatively affect the physiological parameters of the clinical status of animals. The use of the abiotonic feed additive increases the average daily gain of calves by XNUMX gramms compared with the control group. The results of blood tests suggest a reliable stimulating effect of the Abiotonic feed supplement on metabolic processes, increasing the parameters characterizing hematopoiesis. Thus, the Abiotonic feed additive can be recommended for use by animals during the period of active growth and development of the body, to stimulate weight gain, and activate animal metabolism, and prevent anemia and hypotrophy.

The materials on the study of the feed additive Abiotonic in rabbit breeding, as well as the results of organoleptic, microbiological, histological studies and the amino acid composition of rabbit meat of the New Zealand white breed are presented. According to the results of the studies, there was no negative effect of the feed additive on the veterinary and sanitary indicators of rabbit meat, the carcasses were well bled, drying crusts were formed in a timely manner, the muscles were elastic, light pink, white fat, the broth was clear and aromatic. No pathogenic and conditionally pathogenic microflora were found. At the same time, it was noted that the feed additive contributed to the increase in meat of non-essential amino acids by 6,01%, essential amino acids by 9,74%, which increases the biological value of the product. According to histomorphological studies, the Abiotonic feed supplement did not adversely affect the physiological state of animals, muscle tissue and internal organs developed within the physiological norm of rabbits.

The article presents the results of the conducted studies on the effect of the complex fortified preparation "Nitamin" on the quality indicators of meat of broiler chickens of the Cobb-500 cross. The preparation was administered with drinking water at a dose of 1 ml per 1 liter of drinking water, according to the scheme from 2 day to 5 day of keeping and from 15 to 18 day, poultry slaughter was carried out on 42 day of keeping. The composition of the preparation includes vitamins A; D3; E; trace elements organic iodine and selenium. The research material was the muscle tissue of broiler chickens of the studied groups, according to generally accepted methods, the content of amino acid composition and trace elements of selenium and iron was determined according to GOST R 55569-2013 Feed, compound feed, compound feed raw materials. Determination of proteinogenic amino acids by capillary electrophoresis, GOST 31707-2012 (EN 14627:2005) Trace element food products. Determination of total arsenic and selenium by atomic absorption spectrometry with generation of hydrides with preliminary mineralization of the sample under pressure and GOST 30178-96 Raw materials and food products. Atomic absorption method for the determination of toxic elements. According to the results obtained, the meat of broiler chickens treated with Nitamin was superior in amino acid composition to the meat of broiler chickens of the control group (essential amino acids by 14.38%, nonessential amino acids by 10.9%). When studying the content of trace elements in the muscle tissue of broiler chickens treated with Nitamin, an increase in the iron content of 10 mg/kg was noted, no iron was found in the muscle tissue of broiler chickens of the control group.
