Abstract

The Vitazar preparation has a rich natural composition and antioxidant properties due to the high content of fat-soluble vitamins – A, D, E, polyunsaturated fatty acids – linoleic, linolenic, oleic, palmitic, as well as trace elements Ca and K, etc. To study the preparation effects on young male minks, animals of the standard black breed of Scandinavian selection were chosen by origin, live weight and age using the method of analogous groups. A total of 128 males participated in the experiment – 32 heads in each group. The first group of minks was the control one. In three experimental groups, Vitazar was added to the general household ration with a different dose of 1.0.2.0.3.0 ml/head with a frequency of three times a week. The preparation was given during two summer months – July and August. During the experiment, the minks were weighed at the beginning of each month. After slaughter and primary processing, the skins were sorted in accordance with GOST 27769–88.According to the data obtained, Vitazar has a positive effect on the live weight and skin production of young minks. The drug in the diet of males at a dose of 3.0 ml/head contributes to an increase in live weight by 191 g, the skin size by 0.6 dm2, the proportion of defect-free skins by 8.0% and the quality indicators by 4.0%. The optimal dose of the preparation was found to be 3.0 ml/head.The use of Vitazar in the optimal dose in the diet of male minks increased the cost of one skin by 63.3 rubles. Thу “Vitazar” preparation was studied on young minks for the first time.
