Abstract
Reproductive performance is one of the important economic traits in goats. Higher pregnancy rates, birth weight and rapid recovery of doe’s weight after parturition are important reproductive characteristics deciding the benefits of goat rearing. Among various reproductive techniques, synchronization of estrus is recent approach to augment fertility and fecundity in goats.
A total of 725 does were screened at various villages of Kanchipuram district using ultrasound examination for non pregnancy and one fifty non-descript goats were selected and randomly divided into five groups – groups I, II, III, IV and V with 30 does in each group. The first group was considered as control and no treatment was given. In group II, 30 does were treated with progesterone intra-vaginal sponges (AVIKESIL–S) containing 350 mg progesterone, for 11 days and 125 μg of cloprostenol (i.m.) on day 10. In groups III, IV and V besides intravaginal sponges (AVIKESIL–S) in situ for 11 days and 125 μg Cloprostenol (i.m.) on day 10, 100 I.U., 200 I.U. and 400 I.U. of PMSG was administered on day 11 at the time of sponge
removal, in the three groups respectively. Behavioural and physiological signs of estrus were observed in all the does. Estrous induction, intensity of estrus based on behavioural and physiological signs of estrus, duration of estrus, conception rate and fecundity rate were recorded for all the does.
