Abstract

Twelve prepubertal indigenous goats of Assam aged 6 months were divided into treatment and control groups, consisting of six animals in each group. The animals of treated group were fed medroxy progesterone acetate (MAP) orally @ 5 mg/animal/day for 13 days followed by intramuscular injection of 650 I.U. of PMSG on the day of withdrawal of progesterone. The animals of control group received sterile normal saline. All the six treated goats exhibited oestrus symptoms within 42.88±3.84 hours after PMSG injection. The control group of animals also exhibited natural oestrus behaviour after 50.83±6.63 days of saline treatment. The duration of oestrus was significantly (P<0.01) longer (39.50±8.24 hours) in treated group than the control (34.17±2.51 hour) group.
