ABSTRACT
The Kacang goat is one of Indonesia’s prolific native goat breeds, while the Boerka goat is a crossbreed between Kacang and Boer goats. It is widely known that the ovulation rate and litter size in sheep breeds are significantly impacted by the BMP15 (FecXG) and BMPR-1B (FecB) gene alterations. Based on this knowledge, the study’s objective was to determine the presence of BMP15 and BMPR-1B gene polymorphisms and how they affected the prolific traits of Kacang and Boerka goats. This study indicates that the FecXG and FecB mutations were associated with litter size in Kacang and Boerka goat breeds. The FecXG has two genotypes in both Kacang and Boerka goats, namely homozygote wild type ++ and heterozygote mutant carrier G+ with a litter size of 1.56 and 1.65 (Kacang); 1.61 and 1.75 (Boerka), respectively. Meanwhile, FecB mutations produce three genotypes: homozygote wild type ++, heterozygote mutant carrier B+ and homozygote mutant BB with a litter size of 1.00, 1.37, and 1.65 (Kacang); and 1.00, 1.18, and 1.74 (Boerka), respectively.
