摘要
澳洲白绵羊是近年来我国在澳大利亚引进的新品种,其主要用来改善我国种公羊的肉羊品质。试验通过对2469只不同初生体质量澳洲白羔羊的成活率进行调查分析,结果表明,澳洲白绵羊羔羊最佳初生体质量为4.0~6.0 kg,羔羊初生体质量过高(>6.0 kg)或过低(<2.0 kg)均不利于羔羊成活。综合分析认为,在实际生产中,澳洲绵羊白羔羊初生体质量为4.0~6.0 kg较为适宜。
Australian white sheep is a new breed introduced by China from Australia in recent years.It is mainly used as a breeding ram to improve the quality of Chinese mutton sheep.This experiment investigated and analyzed the survival rate of 2469 lambs of Australian white sheep with different primary birth body quality.The results showed that the best birth body quality of lambs of Australian white sheep was 4.0-6.0 kg,and the survival rate was high.High birth body quality(>6.0 kg)or low birth body quality(<2.0 kg)was not conducive to the survival of lambs.Comprehensive analysis suggests that the birth body quality of Australian white lamb is 4.0-6.0 kg in actual production.
