Abstract

ROLE AND IMPROVING QUALITY OF SEX SEMEN IN CATTLE FARMING

Vinod Kumar Sharma*

ABSTRACT

Numerous advantages are offered to farms and the industry as a whole by the use of sexed semen in the development of dairy and beef cattle. Global demand for dairy and beef products is rising, thus there will need to be more attention paid to improve production efficiency. Unwanted male calves that are excess are produced in dairy farming. In comparison to heifer calves, male dairy calves have a higher risk of dystocia, and as an undesirable by product of mating with traditional semen, they are of little economic use. Sexed semen is defined as desired sex, whether it be female or male, that is produced from sperm carrying the X or Y gene. By increasing the number of outstanding heifers and good male germplasm from exceptional bulls utilised for future breeding programmes, sexed semen helps a herd make genetic advancement. In order to effectively divide bovine sperm into fractions having larger quantities of X or Y chromosome-bearing sperm, a number of techniques have been developed, including density gradient centrifugation or swim-up, sex-specific antibodies, free flow electrophoresis, and flow cytometry. The only semen sexing technique that has been shown to yield calves with desired sex with greater than 90% accuracy and is economically feasible is flow cytometry. Other techniques for sperm sex sorting have also been developed, but they still need to be refined for commercial viability. These techniques include centrifugal counter current distribution, free flow electrophoresis, identification of the H-Y antigen, genetic approaches, and others. The purpose of this study was to evaluate the sexed semen technique, the usefulness of sexed semen, and the advantages and drawbacks of sexed semen.
