| Abstract: | The Southern mode of dairy core group was established based on systematically analyzing the mode of high yielding dairy production by selecting and breeding,while combining the practice of the southern dairy production.The mode included the age(parity) structure which the proportion of adult cows and heifers were 66% and 34% and genetic structure which the proportion was 30%,60%,10% in core group,production group and elimination group,respectively. |
| Keywords: | the Southern mode Dairy Core group |
