The results of embryo washing in sheep kazakh short-tailed coarse-haired breed

Abstract

The article presents material on vitrification of sheep embryos. The research was carried out on sheep of the Kazakh short-tailed coarse-haired breed in the farm "Medkhan" of the Almaty region.

Currently, the development and implementation of innovative technologies is a promising industry in all areas of production. Embryo transplantation technology remains one of the priority areas related to the high demand of economic entities for breeding animals with high productivity potential.

One of the characteristics of vitrification is that with an increase in the freezing rate, the concentration of cryoprotectant can be reduced and vice versa. As a result of extensive research conducted over the past 20 years, radically new approaches and methods have been developed that have allowed vitrification to compete with traditional slow freezing.

Vitrification of sheep embryos is an ultrafast freezing of cells into a glassy state without the formation of ice crystals due to a high concentration of cryoprotectant and a minimum volume of solution. Thus, in a straw, the processes of freezing and thawing proceed much faster, compared with slow program freezing, the advantage of the method is the lack of special equipment.

The use of this method of vitrification of sheep embryos helps to reduce the cost of consumables and its use in the field.
