Response of cattle to different dosage of follicle stimulating hormone with Pgf2 alpha followed by Artificial insemination (AI)

This study assessed the effectiveness of Follicular Stimulating Hormone (FSH.) to compare the different dosage of FSH specifically to determine which of the different dosage of FSH could trigger more ovarian response and in the subsequent estrous cycle in terms of Manifestation of estrus; Multiple ovulation of follicles; Number of corpora lutea; Multiple pregnancies; Multiple birth; Number of animal return to estrus and Multiple abortion. Results show that animals treated with 5ml of FSH plus PGF2 alpha had the highest number of ovulated follicles, corpora lutea developed and pregnancies from the first treatment of FSH and in the subsequent cycle with an average mean of 2.58 ± 0.144, 1.58 ± 0.14 and percentage mean of 50.0 ± 25.0 respectively followed by Treatment 1 had a mean of 2.25 ± 0.43, 1.5 ± 0.25, 41.67 ± 14.43, and the least was observed in Treatment III (4ml physiological solution plus PGF2 alpha) with a mean of 1.0 ± 0.0, 41.67 ± 14.43 respectively. On the other hand, Treatment I had one (1) twin birth delivered equivalent to 20 percent of the pregnant animals.
