Pesisir cattle superovulation with various dosage of Follicle Stimulating Hormone (FSH) on embrio production

Abstract

This study aimed to determine the use of various doses of FSH hormone, the number of lutheum corpus and the number and quality of embryos produced in the superovulation program in Pesisir cattle. The experimental design was Analysis of Variance (Anova) in a completely randomized design. The research material used 16 cows from Pesisir cattle that had been synchronized with estrous with CIDR implants for 13 days and were injected with the PGF2α hormone after the release of CIDR, then scheduled AI was performed. The dose of FSH hormone was 16 ml, 17 ml, 18 ml and 19 ml, each treatment consisting of 4 replications. The injection of the FSH hormone was carried out for 3 days at a decreased dose. Collection of donor embryos was carried out on days 6 to 8 after the scheduled AI. The parameters observed included superovulation response, number of corpus luteum, number of embryos and quality of embryos. The results showed that the response of Pesisir cattle superovulation was 81.25%. The average number of CL obtained was 13.75 and embryos for Pesisir cattle was 11.25. The results also showed that the quality of the embryos obtained were grade A 19, grade B 18, grade C 7, grade D 1. It can be concluded that the use of various doses of FSH hormone at doses of 16 mg, 17 ml, 18 ml and 19 ml had shown a superovulatory response. The 17 ml dose of FSH hormone showed a large number of embryos and had the best embryo quality.
