Abstract
To evaluate effects of A639G of the IGFBB2 gene on meat yield traits in Tau Vang chicken, 152 commercial broilers from two different lines (CTU-BT01 and CTU-LA01) were slaughtered at 13 weeks old. Broilers were genotyped using PCR-RFLP/Bsh1236I and carcass traits of interest were measured. Studied polymorphism exhibited a insignificant effect on all meat yield traits. However, a significant effect on breast length (P=0.043), leg weight (P=0.007), shank length (P=0.001) and breast muscle weight (P=0.046) was found in interaction between genotype and two male lines. The CTU-LA01 males with heterozygous genotype AG showed the highest value for these traits. The study shows that the A639G polymorphism has no strong effect on the meat yield traits in Tau Vang chicken.
