Abstract:
The objectives were to determine the estrus and conception responses to the controlled internal drug release (CIDR), Crestar and Polyurethane sponge (vaginal implant containing 1.5 gm of Natural Micronized Progesterone) along with prostaglandin F2α and PMSG protocol and to compare the efficacy of this protocol. In Group I twelve buffaloes received CIDR inserts for 7 d and were treated with PGF2α on day 6th and inj PMSG (600 IU) immediately after CIDR withdrawal. In Group II, CIDR was replaced with Crestar, While In Group III and IV, exogenous progesterone source were Polyurethane sponge (vaginal implant containing 1.5 gm of Natural Micronized Progesterone). In Group 1and III, 100% of buffaloes showed estrus responses, while Group II and IV buffaloes showed 91.67% estrus response. The overall conception rate were 50.00, 63.64, 66.67 and 54.55% respectively. Intra-vaginal sponge impregnated with progesterone with conception rate of (66.67%) provided excellent fertility. The intra-vaginal sponge impregnated with progesterone can replace CIDR and Crestar in buffaloes and costs 1/10th the price, thus reducing the financial implications to livestock owner.
