本研究旨在评估杂合子裸颈和正常羽商品鸡乳房皮肤胶原蛋白含量和I型胶原蛋白电泳分析。在7周时从每个基因型中随机选择总共72只鸡并屠宰。从每个尸体上分离乳房皮肤，分析胶原蛋白含量，并进行I型胶原蛋白的凝胶电泳。两种基因型中，男性皮肤胶原蛋白含量均显著高于女性。在裸颈鸡中，α 1和α 2条带比市售条带更强，表明胶原蛋白已通过不可还原的共价条带交联。正常羽鸡的β和γ带强度高于裸颈鸡。
This study was conducted to evaluate the breast skin collagen content and electrophoretic analyses of type I collagen in heterozygous naked neck and normally feathered commercial chicks. A total of 72 birds from each genotype were randomly selected at 7 weeks and slaughtered. Breast skin was separated from each carcass and was analysed for collagen content and gel electrophopresis of type I collagen was performed. Males had significantly higher level of skin collagen content than females in both genotypes. In the naked neck chickens α 1 , and α 2 bands were highly intensive than the commercial ones indicating that the collagen has become cross-linked by non-reducible covalent bands. On the other hand, normally feathered chickens had higher intensity of β and γ bands than the naked neck chickens.
