Abstract: In the experiment about 6 monthold cross bred F1 of Simmental×Guan ling yellow cattle, Limousine×Guan ling yellow cattle and Angus×Guan ling yellow cattle were ten heads all allocated into three groups for 360 days of finishing trial. The results show that: the ADG of the three kinds of cattle is 1413 g,1485 g,1367 g respectively; the dry matter intake per 1 kg ADG is 6.91 kg,6.42 kg,7.10 kg respectively; the cost of feed per 1 kg ADG is ￥5.23, ￥4.86, ￥5.38 respectively; there are no significant difference in Net meat ratio among three kinds of cattle, the weight among 18 to 24 month about 450 kg to 500 kg .Above results indicate that straight fatting can support satisfactory performance in both growing and finishing. 
