Efficiency of the use of prolactin in “in vitro” cattle reproduction system
Abstract
As a result of research an improved nutrient media for the maturation of oocytes and early embryos cultivation with prolactin was developed. It provides improvement of oocytes maturation to the stage of metaphase II by 84.9-88.3 %, while the cleavage rate is 48.8-55.3 %, and the yield of embryos suitable for transplantation - 19.8-25.5 %.
