| Abstract: | The weight of XiaNan Bovine in different generations and ages were compared with Nanyang Cattle and stabilized crossbreeding cattle which contain 50% and 25% Charolais blood respectively in this research.The result showed that the weight of bulls at the age of 0,6,12 and 18 months were higher than Nanyang cattle(P<0.01),while the weight of cows at the age of 0,6,12,18,24 and 30 months were higher than Nanyang cattle(P<0.01),compared with stabilized crossbreeding cattle,the cows at the age of 0 and 6 months had not significant effects on body weight(P>0.05). |
