The present article provides the results of the commercial farm-based scientific trial conducted in calves up to six months of the age. In the rearing period of young animals, a promising technology would be the way, when premixes are included in the diet in the dairy period. The conducted study showed that the use of fat and oil industry waste as the basis for premixes helps to solve several problems, namely, to expand the ingredient list and provide alternative materials for farm animals, which allows to increase the protein level in animal diet, as well as to solve the problem of disposal the waste from the fat-and-oil industry. The experiment carried out on the Holstein dairy cows positively estimated the studied premix ZP61-2S. The results show that giving it to the calves had a beneficial effect on the digestibility of dry matter, which was better in the animals of the experimental group by 2.1% than in the control and amounted to 75.2%. Nitrogen utilization by animals in both control and experimental groups were not reduced, and the balance was positive. Thus, the ZP61-2S premix in the compound feed for young cattle increases the average daily gain of animals by 6.85%.

Research has been carried out to study the use of a new feed product prepared on the basis of ginger oil cake and feed concentrate from vegetable raw materials “Sarepta” in feeding poultry meat cross Ross-308. These feed products allow to increase the live weight, the digestibility of nutrients in the diet and improve meat productivity. The results of weighing of broiler chickens showed superiority in live weight of the II experimental group - 2612.76 g, where protein-vitamin-mineral concentrate BVMC (S) was used as an additive in compound feed in the amount of 7.5, 10 and 12%, respectively, during the start, growth and finish. The live weight of the I experimental group was 2512.54 g, where protein-vitamin-mineral concentrate BVMC (R) was used as an additive, the dosages were similar to the II experimental group. The weight of the control group chickens was 2370.80 g, respectively. The conducted experience showed that the chickens of the experimental groups exceeded the control analogues in the digestibility of dry matter by 0.27-0.57%, crude protein - by 0.45-1.48%, crude fiber - by 0.7-2.53%, crude fat - by 0.94-2.29%. The results of anatomical cutting of the carcass showed the superiority of the experimental groups.
