| Abstract |
Despite rising demand for goat meat and milk, the Philippines' goat production lags behind other livestock species. Genetic polymorphisms, such as those present in ghrelin (GHRL) gene, might be useful in increasing goat milk production. Ghrelin is a potent hunger stimulant that also aids in energy balance. The purpose of this study is to investigate potential correlations between the GHRL G375A genotype and milk perfromance parameters (average daily milk yield and total milk production) in crossbreed Anglo-Nubian dairy goats. One hundred goat hair follicle samples from three different farms in Misamis Oriental and Negros Oriental were collected for DNA extraction, amplification, and genotyping using the PCR-RFLP. A 0.91 and G 0.09 allele frequencies were observed, while AA 0.81 and GA 0.19 were the genotypic frequencies. To examine how genotypes affect milk yield, a two-way factorial experiment (2 脳 4) in randomized complete block design (RCBD) was used. Different GHRL genotypes were observed to be statistically associated with milk production performance, where dairy goats having GHRL AA genotype produced consistently higher milk yield in the studied population. |
