摘要 试验选用体重约18.5kg,日龄相近,体型体况相似,健康的杜长大三元杂交猪64头,分成对照组和试验组,每组设4个重复,每个重复8头猪。对照组采用三阶段肥育法:20~50kg,50~80kg,80~120kg,试验组采用五段肥育法:20~35g,35~50kg,50~70kg,70~90kg,90kg~120kg,研究两种阶段肥育法对商品肉猪生长性能的影响。结果表明,与传统三阶段肥育法相比,五阶段肥育法提高肉猪增重4.53%,差异不显著(P>0.05);料重比两者相近(2.96对2.97);日采食量提高了4.13%,差异不显著(P>0.05);至120kg出栏,每头肉猪增加直接经济收益8.4元。
