The problem of increasing of livestock and poultry has led scientists to look for measures to improve productivity and reduce costs. One way to solve this problem is to use balancing supplements in the feeding. The study of feeding by protein-vitamin-mineral feed supplement “Efiprot” was carried out on three groups of young white pigs, 12 heads in each group. The experiment consisted of leveling of 15 and a basic period of 127 days. During the rearing period, the animals consumed the feed according to the growth phases, increasing the amount from 1 kg/head (8–15 kg of live weight), up to 1.5 kg/head per day (15–35 kg of live weight) and from 2 kg/head (35–65 kg of live weight) and up to 2.5 kg/head. per day (65–110 kg of live weight). While using in feeding of young pigs of PVMS “Efiprot”, a positive productive effect was obtained. Thus, when introduced to the diet of the tested yong pig the PVMS, the average daily growth of animals has increased by 33–58 g. Accordingly, has increased the final live weight of the animals by 4.05–7.18 kg against the control level. Due to the result of the studies, carrying out the control slaughter, it was found that feeding of the protein-vitamin-mineral supplement “Efiprot” for young pigs on rearing does not have a probable effect on the weight of the stomach, but causes changes in the thickness of the wall of the cardiac zone by 0.24 mm (2.75 %), and reducing the wall thickness relative to the control by 1.04 mm (11.91 %). In the fundus zone of the stomach, there is a tendency to thicken the walls due to the mucous and sere-muscular membranes by 0.36 mm (6.75 %) and 0.35 mm (6.56 %). In the study of the pyloric zone, the thickness of the walls was decreased by 0.46 mm (3.13 %) and 0.73 mm (4.97 %) compared to the control group.The reaction of the intestine to feeding of “Efiprot” to young pigs is caused by an increase in weight and length of 0.06 – 0.2 kg and 0.5 m – 0.83 m. Also it is shown a slight decrease in the thickness of the hollow shell by 0.5 mm (18.3 %) in the second group of animals 0.21 mm (7.69 %). A significant difference was found in the structure of the colon of experimental animals, where there was an increase in wall thickness in the first group by 0.13 mm (5.75 %) and a decrease in the second group by 0.16 mm (7.07 %).
