| 摘 要： | 通过对贵州喀斯特地区胚胎移植安格斯牛初生至12月龄的体重、体尺等生长发育情况的观测,并与原产地同龄段安格斯牛和黎平本地黄牛进行比较。结果表明,胚胎移植犊牛基本适应当地自然条件和饲养管理条件,生长性能较黎平本地黄牛明显提高;公犊各年龄段体重明显低于原产地同龄段公犊,甚至低于胚胎移植母犊;不同年龄阶段日增重,公、母犊均以3月龄以前最快。

| Abstract: | The body weight and body measurements of the embryo transplanting Angus calves was surveyed from its newborn to 12 month-old and compared with the indexes of the original Angus and local Liping calves at the same age.The results showed that the embryo transplanting Angus calves could basically adapt to the local natural and feeding conditions,and its growth performance was significantly better than the local Liping calf.The body weight of the male calves was obviously lower than the original Angus calves at the same age and even lower than the female embryo transplanting calves.The daily gain of embryo transplanting Angus calves(male and female) was rapid before 3 month-old. |
