Observations on Improvement Performance of Yunnan Fuyuan Local Cattle upgraded by Milk Shorthorn |
| |
| Abstract: | We observed and examined the body measurement and weight of local cattle and cross generation F-1,F-2 and F-3 between local and shorthorn cattle at birth,six,twelve and twenty four months old. Weaned cattle of six months old were selected to be the test animal. The result showed that the daily gain of F-1,F-2 and F-3 was 469.1g,603.1 g and 648.4 g, more than that of local cattle. The improved scope was F-1>F-2>F-3,which was the scientific basis to improve local beef cattle. |
