COMPARATIVE EFFICACY OF FSH-P AND PMSG ON SUPEROVULATION IN PASHMINA GOATS

Twenty-eight Pashmina goats were utilized to study the comparative effect of FSH-P and PMSG on superovulatory response. The effect of FSH-P marketed by two commercial firms was compared with respect to the number of corpora lutea and embryos recovered. The difference was found to be nonsignificant. Superovulatory responses with FSH-P (pooled) and PMSG were 16.55 +/- 6.13 and 11.70 +/- 8.07, respectively, and the difference was significant (P < 0.02). Recovery of embryos was significantly higher (P < 0.001) with FSH-P (4.72 +/- 4.33) than with PMSG (2.50 +/- 5.02) treatment. The superovulatory response (number of corpora lutea) and the embryo recovery rate was better in higher age groups (4 to 6 yr) than younger goats (1.5 to 3 yr). The embryo survival rate was higher (54.54%) for recipients operated on under a basal anaesthetics (Triflupromazine hydrochloride USP) than for those operated on under barbiturate anaesthesia (13.64%). The overall conception rate was 34.09%.
