The article presents the results of using fermented forage fish paste prepared from waste from processing of Far Eastern commercial fish in the diets of pregnant sows. The use of this additive in feeding sows had a positive effect on their reproductive qualities, which allowed to increase the multiplicity of sows’ livestock by 3.8-9.7%, large-scale fertility by 1.7-5%, the average daily growth of piglets by 5.4-7.8%, and increase the safety of newborn piglets by 2.2-4.4%. The absolute increase in live weight of sows in the experimental groups during pregnancy was higher by 2.0 kg, 4.4 kg and 4.9 kg compared to their counterparts from the control group. At the same time, the average daily increase in live weight in sows of the experimental groups compared to animals of the control group was higher by 3.7-9.9%, respectively. The best indicators were noted when feeding fish paste fermented feed at a dose of 3 and 6.2% of the nutritional value of the diet.

In the article the effect of different doses of the drug “Lactocormovit” on the milk productivity of cows during the milking period was studied. The animals of the experimental groups had the best milk production. Cows that received the drug “Lactocormovit” in their diet outperformed their peers from the control group in milk yield by 5.6% and 11.4%, respectively. The using of the drug “Lactocormovit” has a positive effect on the chemical composition of milk. According research we found that during the period of experience in cows of the experimental groups increased the amount of milk fat-by 11.45 and 17.71 kg and protein-by 4.84 and 10.18 kg. There is a tendency to improve the physical and chemical indicators of milk.

The article contains material of scientific and economic experiment on the inclusion of herring and pollock processing wastes in rations of swine. The effect of feed addittion on the dynamics of piglets was studied. As a result of conducted research work we established a positive effect influencing on growth, metabolic processes, digestibility of feeds.

The article contains materials of scientific and economic experience on the use of feed flour from Japanese Corbicula and Eastern Galega in feeding young hens. We conducted two scientific research and economic experiments on the inclusion of these additives in the diet of young poultry. Experiments were carried out on young poultry of the Haysex white cross. The purpose of the research work is to study the possibility of including in the diets feed flour from Japanese Corbicula and plant additives made from Eastern Galega. Thus, when feed flour from Japanese Corbicula was included in the diet of young poultry, the following results were obtained: weight gain increased by 14.3-19%. The inclusion of plant-based additives in the diet of young poultry increased the live weight in the experimental groups by 10.5-14.9%.
