【 摘 要 】

This study investigates the effect of FSH supplementation on the resulting number and quality of super-ovulated Pesisir cattle embryos. This study aims investigates the effect of FSH supplementation on the resulting number and quality of super-ovulated Pesisir cattle embryos. After progesterone therapy fifteen Pesisir cattle were each given five injections of FSH followed by AI with Simmental semen. Embryos were flushed out on the sixth to eighth day after AI and counted and graded under a microscope. Cows given 16 ml and 12 ml of FSH produced the highest percentage of A quality embryos (22% and 20% respectively) while no high-quality embryos were collected from those given 14 ml FSH. 12 ml FSH treatment resulted in the highest number of B quality embryos (20%) while a14 ml dose produced less than 7%. One-third of the embryos resulting from 14 ml FSH were C grade but 12 and 16 ml dosages resulted in no embryos of this grade. The highest numbers of degraded embryos were found from cows given 12 ml (60%), while the lowest from cows given 14 ml (33.33%). The percentage of the recovered ovum that remained unfertilized from cows treated with 16 ml, 14 ml, and 12 ml were 33.3%, 66.7%, and 0% respectively. While 14ml dosages of FSH resulted in the highest number of embryos, the higher embryo from a 16 ml FSH suggests that this dosage will produce superior results.
