- Abstract
The purpose of this study was to evaluate the heritability and breeding value for body weight (BW) and beak length (BL) in local Bangkok chicken based on the performance of its crossing with Lohmann laying hen. The material used were 720 crossbred chickens aged of 3 and 7 weeks, resulted from crossing of 24 Bangkok sires and 240 Lohman Brown dams. The method used was field experiment with direct observation on body weight and beak length at 3 and 7 weeks of age. The heritability and breeding value was estimated using sire model. The results showed that the average of body weight was 145.75 ± 23.72 g and 508.83 ± 94.48 g for 3 week and 7 weeks of age. The mean of BL was 1.96 ± 0.13 cm and 2.68 ± 0.12 cm at at 3 and 7 weeks of age. The heritability value at the 3rd and 7th week of age were 0.68 and 0.60; 0.23 and 0.31 for body weight and beak length. The positive breeding values for BW and BL were 45.83% and 58.33%. The highest BW at 3 and 7 weeks were 176.45 g and 606.86 g, respectively. The highest BL at the age of 3 and 7 weeks were 176.45 g and 606.86 g. The heritability value for body weight was higher than beak length. Selection for body weight will give the highest improvement in the next generation.
