Abstract
Relevance. The article presents data on the influence of unconventional feed additives of the Suntar zeolite on growth and development, physiological parameters, as well as meat productivity of fattening pigs in Yakutia.
Methods. For the experiments, 3 groups of animals were formed with 15 animals each. The rations of the experimental animals were identical, except for additional feeding of unconventional feed additives in the experimental groups.
Results. The use of Suntar zeolite in experimental groups of pigs allowed to improve the growth and development of animals by 3.02% and 6.68%, respectively. At the same time, in terms of average daily growth, the control group of pigs yielded to experimental groups of animals by 7.42% and 15.17%. During the experiments, a difference was found in the indices of the morphological composition of fattening young pigs. The control group of young animals by the number of red blood cells yielded to experimental groups of pigs by 2.00% and 4.00%. By the number of leukocytes, the control group of the group lost 1.02% and 1.16% to the experimental groups of animals. At the end of the experiment, a control slaughter of animals was carried out. Qualitative differences were established between the superiority of the experimental groups over the control group in terms of carcass weight by 5.25% and 1.98%, by internal fat yield by 0.71% and 0.64%, slaughter yield by 0.71% and 0.64 %, according to the meat content by 0.9% and 2.97%, as well as the share of fat 0.54% and 0.74%. Thus, the use of unconventional feed additives of the Suntar zeolite in the fattening of young pigs has shown effectiveness.
