| Abstract: | In this paper ,the method of grey relation analysis was used to design the power weight allotment of factors in the synthetic judgement of multiple characters in livestock , and then the method of grey appraisal was applied to the synthetic judgement of 9 Black and White dairy cows. The results showed that it was possible to use grey apprasial to judge livestock. This method has peculiarities of reasonableness accuracy and simplicity,and can be used to the synthetic judgement of other animall. |
