Abstract

Thirty-six non-infectious repeat breeder cows were selected on the basis of typical fern pattern, negative white
side test, normal pH of cervical mucus and <4% polymorphonuclear (PMN) cell count in endometrial content.
Selected animals were randomly distributed in three groups containing twelve animals each. Group-I and Group-
II were treated with inj. GnRH @ 10 mcg and inj. hCG @ 2000 IU by intramuscular route, respectively on day 5
post-AI, whereas group-III served as controls. Conception rates in group I, II and III was recorded as 58.3, 66.7
and 25.0%, respectively. Thus, hCG treatment on day 5 post-AI improved conception rate in non-infectious repeat
breeder cows.
