Perfection of pairing system in mink (Mustela vison) during cage keeping

The perfection of a pairing system in mink was considered on basis of optimization of regime of males using on heat. It was shown, that planned using of males on heat to some degree facilitates the realization of latter (everyday only the part of males can be used) without a decrease of reproduction parameters. At the period of mink pairing for every day of heat PNG can not exceed 1,2; otherwise the males must obtain 1,5-day's relaxation.
