摘　　要：通过对甘肃省酒泉地区45头胚胎移植荷斯坦奶牛初生、6月龄和12月龄阶段的体尺、体重指标进行测定，并将其与相关资料记载的甘肃黑白花奶牛、中国荷斯坦奶牛、本地奶牛同期体尺、体重指标进行对比分析．探求胚胎移植荷斯坦奶牛0～12月龄体尺、体重的生长规律。结果表明：胚胎移植荷斯坦奶牛的体尺、体重累积生长随日龄的增加而不断增加．其体尺、体重累积生长的走势与甘肃黑白花奶牛、中国荷斯坦奶牛和本地奶牛相似。0～6月龄阶段．胚胎移植荷斯坦奶牛的生长速度慢于体斜长的生长速度；在6-12月龄阶段．管围和体斜长的生长速度慢于体高的生长速度。The body size and body weight of 45 newborn, 6-month, 12-month embryo-transferred Holstein cows in Jiuquan area of Gansu Province were determined and compared with that in Gansu Friesiml cows, Chinese Holstein cows and local cows in the same stage. The growth laws of body size and body weight of 0-12 month-old embryo-transferred Holstein cows were discussed. The results showed that the accumulated growth of body size and body weight of embryo-transferred Holstein cows gradually increased with the age. The accumulated growth trend of its body size and body weight was similar with that of Gansu Friesian cows, Chinese Holstein cows and local cows. The growth speed of 0-6 month -old embryo -transferred Holstein cows was slower than the growtb speed of body slanting length. The growth speed of cannon circumference and body slanting length of 6-12 month-old was slower than that of body height.
