Abstract:
The present study was carried out to determine how ApoB2 gene polymorphisms are related to growth-related traits and carcass characteristics of Noi chickens. A total of 183 birds were examined in the study. Body weight was recorded individually at days 1, 35, 63, and 91, and carcass parameters were determined at 91 days for all chickens. For determining single nucleotide polymorphisms, the PCR-RFLP method was used with the help of AcyI restriction enzyme. A polymorphic site was found in the population, with the frequencies of 11, 12, and 22 genotypes being 0.18, 0.67, and 0.15, respectively. At the end of the experiment, better body weight (965-976 g/bird) and daily weight gain (10.5-10.6 g/bird/day) were found in chickens with 11 and 12 genotypes. Carcass parameters were superior in chickens carrying these genotypes (P<0.05) except for thigh and drumstick weight. In breeding selection for improving growth and carcass traits in Noi native chickens, allele 1 was more advantageous.
