摘要
新疆于2009年从德国引进了一批优质冻精，并面向疆内20多个县（市）推广。本文根据2012年初项目区抽样数据初步分析了该批冻精的使用效果。结果显示德系冻精的杂交优势明显优于国内冻精：实验组F1代犊牛孕期发育情况优于对照组，其出生重平均在40kg以上，比对照组高出2-5kg；犊牛出生后的生长速度比较快，平均日增重均在600g以上，比对照组高出100-200g；6月龄后体斜长、胸围、管围、体高较对照组均有不同程度的提高，体型结构进一步得到优化。
Xinjiang imported a number of high-quality frozen semen from Germany in 2009,and distributed them to many areas. The article analyzes the effects of the use of frozen semen ,based to sampling data collected by a project in early 2012. The results showed the offspring of imported semen from Germany were significantly superior to these of domestic semen： The development situation during pregnancy of the Flgroup calves are superior to the control group ;the average birth weight was above 40 kg, 2-5 kg higher than the control group; the calves grew faster after the birth, and the average daily weight gain were above 600 g, 100-200 g higher than the control group; after six month age, body length, chest circumference, circumference of cannon bone, body high improved in varying degrees compared with the control group, the body structure has been further optimized.
