Summary: Prebiotics are an effective technological element of increasing the productivity of animal husbandry. Currently, prebiotics are being broadly used in cuniculture. Those drugs are a promising means of stimulating growth and development of animals. Prebiotics optimize the metabolic processes and increase the level of nutrient metabolism. Our studies revealed the effect of a prebiotic drug, which contains lactic and succinic acids, aminoacids, vitamins А, В1, В2, В3, Е, on the growth intensity of rabbits. The studies were performed on the young 34 to 160-days-old rabbits of the Hyplus meat hybrid. Animals of the control group were fed ad libitum with full-diet granulated mixed feeds and had free access to water. Animals of the experimental groups were fed feeds of the control-group diet, supplemented by prebiotic additive Prebiolakt-Kr in the doses of 1.5, 2.0, and 2.5 g/kg of the live weight. Every 14 days during the feeding period, the growth intensity of the rabbits was controlled according to individual live weight and average daily increment. Addition of Prebiolakt-Kr to the rabbits’ diet increased the live weight of animals by the end of feeding. We verified and confirmed the positive effect of the prebiotic on the intensity of growth and development of the growing rabbits. According to the absolute increment, the advantage over the rabbits in the control accounted for 7.9–11.9%. Feeding the supplement increased the meat volumes of the rabbits. Also, Prebiolakt-Kr added to the diet caused higher chest girth/diagonal body length index. The animals that were receiving the prebiotic feed supplement used the diet more effectively and had better metabolism of nutrients. The studies revealed a dose-dependent effect of prebiotic on the growth intensity of the rabbits. At the same time, the best stimulating action was displayed by supplementing the diet of the young rabbits by 2.0 and 2.5 g/ind. of Prebiolakt-Kr. The conducted studies have confirmed the benefits of using prebiotic drugs in rabbit husbandry, which improve metabolism and increase bodyweight gain.
