【摘要】：本试验选用淅川乌骨鸡、培育的新品系青胫隐性白羽鸡和黄胫丝毛鸡,组成淅川乌骨鸡♂×淅川乌骨鸡♀、淅川乌骨鸡♂×青胫隐性白羽鸡♀、淅川乌骨鸡♂×黄胫丝毛鸡♀3个组合,分析F1代0周龄、6周龄和16周龄的肤色、胫色的变化,胫色与肤色的关系及淅川乌骨鸡♂×黄胫丝毛鸡♀肤色胫色与性别的关系等。结果表明:1从肤色上分析,纯繁组、淅川乌骨鸡×青胫隐性白组没有浅乌肤出现,只有深乌和黄白两种肤色。而淅川乌骨鸡×黄胫丝毛鸡组浅乌肤个体较多。3个组合的F1代,随着的周龄增加,乌肤比例增加,浅肤个体减少。2从胫色看,纯繁组、淅川乌骨鸡×青胫隐性白组的后代胫色逐渐加深,至16周龄,几乎全部是深乌色。淅川乌骨鸡×黄胫丝毛鸡组的后代深乌胫的比例变化较少,6周龄时浅乌肤个体几乎都变成了黄白胫,所以黄白胫的比例急剧增加。整体来看胫色与肤色基本呈现一致性,深乌胫时,肤色多为深乌肤且深乌胫深乌肤的比例呈上升趋势。本研究显示:淅川乌骨鸡×青胫隐性白杂交组后代能较好地保持亲本的胫色肤色,且随着周龄的增加胫色肤色具有时效性。3个组合不能根据胫色和肤色进行雌雄鉴别。
[Abstract]:In this experiment, Xichuan silk-bone chicken was selected, and the new lines of green shank recessive white feather and yellow shank silk hairy chicken were selected to form Xichuan silky chicken 脳 Xichuan silky bone chicken, Xichuan black bone chicken 脳 green shank recessive white feather chicken. Three combinations of Xichuan silk-bone chicken 脳 yellow tibial silk fowl were used to analyze the changes of skin color, tibial color, the relationship between shank color and skin color, and the relationship between skin color and sex of F _ 1 generation of 0-week-old and 16-week-old fowls, as well as the relationship between shank color and skin color, and the relationship between skin color and sex of Xichuan silky chicken 脳 yellow tibial silk chicken. The results showed that in the pure propagation group Xichuan silky chicken 脳 blue-shank recessive white group had no light black skin but only dark black and yellow white skin color. But in Xichuan silky chicken 脳 yellow shank silk hair chicken group, there were more light black skin individuals. With the increase of the age of three combinations, the black skin ratio increased, and the shallow-skinned individuals decreased .2 from the tibial color, the pure reproduction group. The shank color of Xichuan silk-bone chicken 脳 blue-shank recessive white group gradually deepened to 16 weeks old, almost all of them were dark black color. The ratio of deep black shank of Xichuan silky chicken 脳 yellow shank silk wool chicken group had little change at 6 weeks of age, so the proportion of yellow and white shank increased sharply. As a whole, shank color and skin color are basically consistent. When dark black shank, the proportion of deep black skin and deep black skin is on the rise. The results showed that the offspring of Xichuan silk-bone chicken 脳 blue-shank recessive white hybrid group could maintain the tibial color of their parents, and the tibial complexion had a time-effect with the increase of the age of the week, and the three combinations could not be identified according to the tibial color and the skin color.
