Improvement and introduction of modern methods of reproductive biotechnology of sheep in the Institute of Animal Biology NAAS

Abstract

The article presents the scientific achievements of researchers of the Institute of Animal Biology NAAS in reproductive biotechnology in sheep breeding. The Ukrainian-Polish experiment on improving the in vitro method of sheep fertilization, which ended with the birth of the first lamb in Ukraine, is covered in detail. The scientific achievements of the staff of the institute were the basis for the introduction of an improved method of laparoscopic insemination of sheep in Ukrainian farms. Laparoscopic insemination of local breeds of sheep of Lviv, Zakarpattia, Kherson and Dnipropetrovsk regions with sperm of sheep of specialized fat breeds was carried out and fertilization of more than 80% was obtained. Also, scientific and practical work was carried out to improve and implement methods of stimulating superovulation in ewes of the Texel breed, non-surgical washing of embryos and their transplantation to bright recipients of the Ukrainian Carpathian breed.
