EFFECT OF GENOTYPE OF POU1F1 GENE AND FEED SUPPLENMENTATION ON CARCASS CHARACTERISTICS OF DINH HOA INDIGENOUS GOATS

Abstract

Dinh Hoa indigenous goats experimental goats were randomly divided into 6 treatments (Two genotypes D₁D₂ and D₁D₁ of gene POU1F1, each genotype was supplied mixed feed with the level from 0, 15 and 30%), there were 8 heads goat in each experimental unit. The goats were assigned the same live weight, housing, environment and feeding conditions. The experiment was replicated 3 times and observed from 3 -12 month olds. The results showed that, the percent of empty weight, percent of carcass weight and percent of lean meat increase for the goats supplemented mixed feed from 0, 15 and 30%, nevertheless the significant different there were only in treatments of D₁30 (D₁D₁ genotype and supplied 30% mixed feed) and D₁0 and D₂0 (D₁D₁ and D₁D₂ without mixed feed). There was no different between treatments of percent of born. The analysis results showed that, the genotypes of POU1F1 gene and inteaction between supplemented feed and genotype there was no affected to percent of empty weight, percent of carcass weight and percent of lean meat. Supplemented feed there was affected to percent of empty weight, percent of carcass weight and percent of lean meat (P<0.001), but not to the percent of born (P≥0.05).
