| Abstract: |
| Five mating combinations were made using different breeding lines of Saanen in this research.The results of the groeth and development in the lactation period showed: hybrid combination Ⅲ(Xinong-west German F1♂×Xinong♀) developed best;hybrid combination Ⅰ (west German♂×Xinong♀) and purebred combination Ⅰ (Xinong♂×Xinong♀),the next;while hybrid combination Ⅱ(British♂×Xinong♀) and purebred combination Ⅱ(British♂×British♀) developed poorer.These sequences of growth and development of each part in the lacation period were height,length,width and body weight. |
