RESPONSE OF MURRAH BUFFALOES TO DIFFERENT SUPEROVULATORY DRUGS

Abstract

An investigation was carried out to determine the efficacy of four superovulatory drugs i.e. Folltropin (Vetrepharma, Canada), FSH-P (Schering, USA) Ovagen (lmmuno Chem. Products Ltd. Auckland NZ) and Folligon (lntervet, Holland). These gonadotropins were administered to Murrah buffaloes in mid luteal phase. The index for inducing the response of Murrah buffaloes to these superovulatory drugs was presence of corpora lutea and number of embryos recovered. It was found that the response was higher in Folltropin (5.5 ± 1.0 and 2.75 ± 1.49) as compared to all the other three groups i.e. FSH-P (3.17 ± 0.38 and 0.5 ± 0.14), ovagen (2.5 ± 0.92 and 0.85 ± 0.40) and Folligon (1.0 ± 0.7 and 0.0 ± 0.0).
