| Abstract: | Nanyang cattle is famous for its large body size, dual purpose for meat and draft, roughage-tolerance and strong adaptability. Xianan and Pinan cattle are beef cattle breeds bred basing on Nanyang cattle. The weight growth and early maturity of the breeds were studied by using of model-based approach in this paper. The results showed that Xianan and Pinan cattle have the characteristics of early maturity and strength growth, higher weaning weight, 12-month-old body weight are of 56.60% and 62.21% of that in 36-month-old for Xianan and Pinan cattle respectively. Among them, |
