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 application of the protein hydrolyzate of plant origin «Abiotonic» on New Zealand White rabbits at the rate of 1 ml/kg of live weight. In the course of the work, a number of studies of the amino acid composition of the liver and heart of rabbits were carried out in order to determine the effectiveness of the feed additive. The data obtained indicate the ability of «Abiotonik» at a dose of 1 ml/kg of live weight to have a significant effect on improving the protein value of rabbit’s products. As a result, the use of the feed additive «Abiotonic» in rabbit breeding improves the quality of the products obtained.
This article presents the results of a study of the amino acid and microelement composition of eggs of laying hens of the egg direction of the Hisex Brown cross when using the Abiotonik feed additive at a dose of 1 ml/kg of body weight every other day. It was found that in the eggs of laying hens of the experimental group, the content of nonessential amino acids increased by 12,3 %, partially nonessential amino acids – by 13,3% and irreplaceable – by 14,7% as compared to the control group. In addition, in the eggs of laying hens of the experimental group, the content of selenium (Se) and iron (Fe) is 59,3 % and 40 % higher, respectively, compared to the control group. As a result of the study of the effect of this feed additive on the egg productivity of laying hens, it was found that the weight of eggs of birds in the experimental group increased by an average of 1,1 g, and egg production over a period of 7 days (44th – 51st days of the experiment) increased by 15 eggs compared to the control group.
The article presents the results of experimental studies when introducing into the diet of turkeys a composition of feed additives used to prevent the anthropogenic impact of pollutants on the body of animals and poultry. In order to determine the effectiveness of the composition of feed additives, we studied the clinical status of turkeys and determined morphobiochemical blood parameters. It was found that the composition of feed additives «Productive Hepato» and «Maxisorb®» contribute to an increase in the live weight of turkeys and does not have a negative effect on the physiological parameters of birds. According to the biological value of the meat of turkeys receiving this composition of feed additives, the meat of turkeys of the control group is superior. Thus, this composition can be recommended for use by turkeys in order to prevent contamination with pollutants of various origin of poultry slaughter products.
Whole milk substitutes are widely used in feeding calves in the dairy rearing period, when the use of whole milk is unacceptable due to diseases of contagious etiology of mothers, or for economic reasons. The purpose of our research was to determine the effectiveness in calf feeding of the new substitute for whole milk «NutrilactPro» developed within the Rusagro group of companies in comparison with analogues designed for use from the first days of life of calves. Scientific research was conducted in the Moscow region. Using the paired-analogues method, two groups of calves of Holsteinized black-motley breed were formed, 12 calves in each group having the same body weight and a group cage housing. Blood samples were taken for clinical and biochemical analysis before and after the experiment. Calves were reweighed every 15 days.
