| Abstract | The investigation of genetic pattern of MYF5 and its association with growth and carcass traits were performed in Thai native chickens and their Crossbred. The PCR-RFLP/HhaI technique, was used to identify the genetic variation of MYF5 from a total of 311 of blood samples were collected from 4 groups of chickens including Thai native chicken (Chee) (100NT), 50% Thai native crossbred chickens (50NT), 25% Thai native crossbred chickens (25NT) and commercial broiler (0NT). Association analysis of the MYF5 with growth and carcass traits ware performed by Proc GLM. The results showed 3 genotypes: AA, AB and BB of MYF5 pattern. The frequency of AA genotype was range between 0.000-0.041, the frequency of AB was 0.108-0.432 and the frequency of BB was 0.527-1.000. In addition, the AB genotype showed association with a higher average body weight at 2 weeks of age in 25NT which body weight was 196.13±8.93 g, and the AB genotype was also associated with an increased percentage of local carcass and drumstick percentage in the 50NT which accounted for 80.75±0.68% and 12.04±0.76%, respectively. Additionally, the AB genotype tended to increase a percentage of breast in 100NT at 15.67±0.33 g. The finding indicated that the genetic variation of MYF5 could be associated with body weight at 0-2 weeks and carcass traits in 100NT, 50NT and 25NT. This suggesting that the MYF5 has potential to be used as genetic markers to facilitate selection of growth efficiency and carcass traits in Thai native chicken breeds. |
