Comparative Evaluation of Therapeutic Approaches for Fecundity Improvement in Osmanabadi goats

Improvement of fecundity was studied in Osmanabadi goats following estrus synchronization with different approaches viz. hormonal, energy and mineral-vitamin protocols. Total twenty four (24) goats were confirmed as non pregnant through ultrasonography and were equally divided into three groups viz. Group 1 goats from hormonal protocol were administered injection GnRH @ 4μg on the 1^st day followed by injection PGF_2α @125μg on 7^th day and second injection of GnRH @ 6μg was administered on 9^th day. Group 2 energy protocol consists of 8 goats were treated with Inj GnRH @ 4μg on 1^st day and Inj PGF_2α @125μg on day 7^th and 5% Dextrose injection10ml/kg b.wt. was administered on day 7^th intravenously, whereas Group 3, goats from the mineral-vitamin protocol were administered injection GnRH @ 4μg on the day 1^st followed by injection PGF_2α @125μg on 7^th day and micro minerals 2 tabs for 10 days starting from 1^st day with Inj. Vit A, D₃, E @ 3ml intramuscularly on 7^th day. Treated goats were followed for estrus exhibition by visual observations and further pregnancy rate was confirmed by ultrasonography. Estrus was observed as 87.50% (7/8) in hormonal protocol group, 75.00% (6/8) energy protocol group and 62.50% (5/8) mineral-vitamin protocol group. Further, fecundity percentage recorded on kidding was found to 2.1 in hormonal protocol group, 1.5 in energy protocol group and 1.6 in mineral-vitamin protocol group. It was concluded that hormonal protocol can be employed to improve fecundity in goats.
