Variation of qualitative and quantitative traits in day old chick crossbred of Bangkok and Lohman laying hens

Abstract

The purpose of this research was to evaluate the body weight based on feather color and shank color in one-day-old (DOC) crossbred of Bangkok and Lohmann laying hens. The research material used was 373 Crossbred Day-Old Chick (DOC). The variables measured were body weight as quantitative traits, therefore feather and shank color as qualitative traits. The results showed that the feather color of Crossbred chicken varied, namely brown, grey, white, yellow, and black, with a percentage of 17.69%, 1.87%, 6.87%, 42.62%, and 30.83%, respectively. The shank colors were yellow and black, with a rate of 67.56% and 32.42%, respectively. The mean body weight for brown, grey, white, yellow, and black feather color was 40.12 ± 4.38 g; 42.43 ± 2.76 g; 40.65 ± 3.03 g; 39.82 ± 3.38 g; and 39.61 ± 3.67 g, respectively. The analysis showed that body weight was not different between feather colors. The highest percentage of color for feather and shank was yellow. The quantitative traits measured in crossbred DOC of Bangkok and Lohmann were above the DOC national standard. The results showed that the dominant qualitative trait in Crossbred chicken for feather color was yellow at 42.62%, shank color was yellow at 67.56%.
