Abstract

An attempt was made to asses pre-insemination use of Gonadotropin Releasing Hormone (GnRH) in 20
noninfectious repeat breeding Gir Cows and its crossbreds (G x HF, G x J ). Buserline 10 ug was injected
intramuscularly just before insemination in treatment group of animals. Conception rate in the treatment group
was 20% higher than the control. GnRH had no influence on subsequent serum progesterone level on 14th and
. 22nd day post-insemination. The properties of estrual mucus discharge (pH, Spinnbarlceit test and in-vitro sperm
penetration test) differed significantly between fertile and nonfertile estrus.
