Abstract:

The trial was conducted to discuss the characteristic on slaughter quality and organ development of Hebei domestic chiks. Each of 8 chicks aged 150-days-old of Hebei domestic and caged chicks (Jingbai) were selected to slaugher and determine the slaughter indices. The results indicated that the ability of producing meat on domestic chicks were lower than which of Jingbai chicks, the weight and slaughter weight on domestic chicks were significant lower than that of Jingbai(P<0.01). The slaughter rates on domestic chicks were significant higher(P<0.01) and the percentage of abdominal fat were significant lower 37.20% (P<0.05) than which of Jingbai chicks. Compared with Jingbai chicks, the immune apparatus and digestive system were farther development, the body was thinner and head was smaller on domestic chicks. In conclusions, Hebei domestic chicks had relatively particular advantages on slaughter characteristic and organ development, which supplied necessary reference for breeding of domestic chicks.
