COMPARATIVE STUDY OF FIXED TIME ARTIFICIAL INSEMINATION AND CONVENTIONAL PROTOCOLS IN RJM CATTLE FARM, SAN FELIPE, ZAMBALES
Beef cattle production is a promising livelihood for local farmers, coupled with the use of artificial insemination hastening the population of genetically superior cattle. The farm is suitable for raising improved cattle breeds and adapted to local conditions. Artificial insemination requires the skill of the technician, posing a factor in the failure and success rate of pregnancy. It compares the conventional treatment and fixed-time artificial insemination using different drug combinations. The combination of controlled internal release drug with human chorionic gonadotropins effectively increased the pregnancy rate of the cows treated using fixed-time artificial insemination compared to conventional artificial insemination. It effectively surpassed the conventional treatment by at least 6% in inducing estrus while the pregnancy rate increased by at least 16% in beef cattle production. The protocol may further be studied in other climate-type environments and provinces to validate the efficacy of the result.
