Increase of fertilisation rates in cows by biologically active matters with bull sperm

M. M. Sharan, I. M. Yaremchuk

The results of biologically active matters (BAM) influence entered with sperm of stud bulls on fertilization rates in cows study are shown in this article. It is set, that entering BAM (oestrofan, inosin, unithiol, gluthatione, L-cysteine) with bull sperm raises the indexes of animal reproductive function (percent of fertilizations after the first insemination, number of successful inseminations, insemination index, number of sperm doses for one insemination), that has the important value for improvement of efficiency of artificial insemination in cows and heifers.
