Abstract

For diary herding, milk production is one of the determining factors of effective actions. That is why it’s very important to get a high percentage of heifers into a processing of herd reproducing, which became possible after introduction of sexed seed – sperm, which cells are divided concerning the sex. Using of sexed seed allows us to repair the herd more quickly, and also to increase the realization volume of heifers by breed enterprises, which very good influence on their profitability. Provided of researching analyses showed us, that using the seed divided by sex into a large agricultural enterprise, the fertility rate is lower on 5-8%, than we will use the traditional seed, and female calves are much higher.

Highlights

Nowadays one of innovative methods of cattle reproduction is using of genetically material, separated by sex. [1, 2]
Into the enterprise sexed seed is used more for insemination of clinically healthy heifers, concerning the certain scheme: heifers are usually inseminated by sexed seed and after 30 days are required an ultrasonic control of the stack capacity of animals and if results won’t be satisfied-animal should go through the same procedure again, but using the sexed sperm only
The traditional seed uses for cows of the second lactation and more, and heifers, which were treated before

Summary

Introduction

Nowadays one of innovative methods of cattle reproduction is using of genetically material, separated by sex. [1, 2]. Nowadays one of innovative methods of cattle reproduction is using of genetically material, separated by sex. Using of seed, separated by sex, gives an opportunity to get 80% heifers from all the calves received, which in turn, allows to renew the herd with the first heifers much quicker and if necessary to increase the herd annually [4, 7]. Despite on visible advantages , researches and practitioners don’t have one common point of view concerning the using of sexed seed. Studying of influence the sexed seed using for reproductive qualities of cows is relevant [3]
