摘要
以1020只0～24周龄的火鸡为材料,测定其胫骨长、胸骨长和增重值。结果表明,布特火鸡商品代的体重生长拐点为16周龄,16周龄时公鸡的平均体重为9.359kg,母鸡为6.758kg。在生长前期胫骨的生长强度高于胸骨,生长后期胸骨的生长强度高于胫骨。说明布特火鸡具有生长快、耗料较低的特点,是具备良好生产性能的优良禽种,为火鸡的生物学种质特性研究提供了基础资料。
The function of growth law of 1 020 turkeys at the age of 0～24 weeks, including the number of tibia, breastbone,gaining weight were studied.The results show that the BUT turkey's growth inflexion is 16 weeks old and the average weight of cocks is 9.359 kg,but hens is 6.758 kg at the age of 16 weeks.Tibia′s growth intensity is higher than breastbone in the prophase of growth, but reverse in the anaphase of growth.So BUT turkey is a kind of excellent bird with fine product capability for its characteristic of faster growing and lower consuming. The research offered basic materials to study biological species characters.
