| Abstract: | This paper researched the heterosis and growth characteristic traits of hybrid of Rongchang and Yorkshire. The result showed that the hybrid, compared with the two parent, had significant heterosis on the traits of mean weight, day weight gain and growth intension. Meanwhile, the hybrid grew very fast and had high weaning weight, and the adaptability to the environment?the ability of stress resistant were higher than those of the two parent. All those proved that hybrid of Rongchang and Yorkshire was a good crossbreeding. |
