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
