Abstract

The article presents the study of qualitative and quantitative methods of sperm quality assessment. After receiving sperm from bulls-producers of meat breeds, the authors clarified the nature of sexual reflexes behavior, the best representation of which was shown by bulls-manufacturers of Kazakh whiteheaded breed, while the bulls of the Charolais breed showed aspermatism and
weak sexual reflexes. The indicators of the sperm quality of bulls-manufacturers are reflected in parameters such as amount of sperm released, density, mobility and concentration. When examining the quality of sperm, the counting chambers "Leja" were used, in comparison with glass, while the concentration of sperm in the "Leja" chamber was calculated to be 1.12 times greater in comparison with the glass.
