The influence of dihydrochloride -2-methyl-4-dimethylaminomethylbenzimidazol-5-ol on the reproductive ability of the silver-black fox

The silver-black fox belonging to the LLC breeding farm “Vyatka” of the Kirov region was used in the work. We used Arkusit, TU 9325-005-51022776-2007, (Developed by the N.M. Emanuel Institute of Biochemphysics and the K.I.Skriabin Moscow State Academy of Medical Sciences), is introduced without any time limits. 2 groups were formed from breeding females of the silver-black fox, according to the principle of analogous groups: control (n = 1235) and experimental (n = 1164). From breeding males of the silver-black fox, 2 groups were formed according to the principle of analogous groups: control (n = 243) and experimental (n = 217). During the experiment, animals of both groups received the general economic ration. Preparation Arkusit was introduced into the feed of breeding animals in 10-day courses with 10-day breaks for 2 months before rut and before whelping at a dose of 0.004 mg / kg of body weight. As a result, there is a decrease in the number of missed and an increase in the number of safely whelped females, an increase in the safety of live puppies and, as a consequence, an increase in the number of registered puppies per successfully whelped female from 4.9 in the control group to 5.6 puppies in the experimental group. Preparation Arcusit promotes an increase in the number of working males, their polygamy, an increase in the number of covered and safely whelped females, an increase in the number of puppies born per male (5.87 puppies) in comparison with the control group.
