Abstract

The embryo recovery following superovulatory (SOV) treatment using equine chorionic
gonadotrophin (eCG) and porcine follicular stimulating hormone (FSH) in native Rathi (Bos
indicus) cattle was studied. In treatment I (n=33) 2000 IU of eCG was injected on day 8 of the
natural estrus. In treatment II (n=17) donors received six 12 h im descending doses of porcine
FSH (Super OV, Ausa International, USA) on day 8 to 10 of natural estrus. Animals were
induced to estrus by PG injections followed by two inseminations 12 h apart at standing estrus
and embryos were recovered by non-surgical means. The overall superovulatory response in the
two treatments was 81.8 and 94.1 percent, respectively. Significant (P<0.01) differences were
observed between the treatments for the superovulatory response and number of unfertilized
ova (UFO) recovered. The results suggest that superovulation and embryo recoveries in native
Rathi cattle are better with FSH than eCG.
