Synchronicity in the timing of sexual activity of females and males of the veiled arctic fox in the conditions of fur farming

Animal husbandry, like all agriculture branches, currently requires optimization directly in relation to the approach to the physiological cycles of animals. The industry is relatively young, the domestication of animals is still ongoing, and the semelparity of animals has its own certain nuances, which leads to the need to adapt to market conditions. The article presents the results of the researches conducted in the Republic of Tatarstan (CJSC «Biryuli») on the study of the influence of the start date and the nature of estrus on the reproduction indicators of female Arctic foxes. The work of males based on the results of reproduction of females mated by him was studied. The data obtained indicate that the best reproduction rates are in females mated by males in the early stages of estrus. Knowledge about the physiology of animals and the ability to control the timing of female estrus and sexual activity of males, can help to look at the possibilities of production, more comprehensively.
