Use of sexed semen for reproduction in dairy cattle breeding

Abstract

Today, farms use traditional semen and sememen divided by sex for insemination. The use of sexed sperm and the increase in the number of heifers in the offspring due to this will allow breeding enterprises: to ensure optimal parameters for entering the first calves into their own herd; refuse to acquire expensive breeding young from other farms; significantly reduce the cost of raising gobies sold for meat; reduce the number of difficult calving and reduce culling of animals for gynecological diseases; improve the economic condition of the enterprise.

The article provides the results of the use of sexed sperm in one of the farms of the Kirov region. As a result of the studies, it was found that the use of sexed semen makes it possible to significantly increase the number of calves in the obtained offspring by 2 times compared to the use of traditional seed 94.3% versus 48.2% of the use of traditional semen.

The effectiveness of the use of sexed semen is significantly higher when used on heifers: an increase of 7.5% in the effectiveness of the first insemination; a 41.9% decrease in steely animal attrition and a 0.2% decrease in abortion rates.

An essential condition for the successful use of sexed semen is the health of the herd, the qualification of an artificial insemination technician and a veterinarian.
