Study on the Gembrong Goat Inbreeding in Tumbu Village, Indonesia

Abstract

Gembrong goat is an Indonesian breed originating from Bali Province that is very rare, having a high level of inbreeding. The inbreeding coefficient (Fis), inbreeding rate (IR), and inbreeding probability (PI) values of Gembrong goat were estimated in Tumbu village, Bali province, Indonesia. Previous studies provide data on the pedigree records of goats in 2015. According to research, the Fis value of Gembrong goats at Tumbu village was 0.413, putting them in the high category (Fx > 0.125). The IR value in the Gembrong population at Tumbu village was 0.025, putting it in the high group (IR > 0.020). The PI value in the F1 Gembrong population was 0.184, which was in the low category (PI 0.50). In conclusion, the elevated Fis and IR values in Gembrong goats were caused by a small population size. In the future, the Gembrong goat recording system will be critical for reducing inbreeding.
