摘　　要：用青绿饲料黑麦草部分替代精料饲喂长嘉母猪 ,研究替代后对母猪繁殖性能的影响 .研究结果表明 ,用 2 0 %～ 30 %黑麦草代替精料 ,母猪所有繁殖指标与对照组相比没有显著差异 ,并且有较好的经济效益 .The objective of this study was to evaluate effects of partial substitution of concentrate with ryegrass on reproductive performance in Changjia sows. Twenty Changjia sows were divided into two groups. Sows in control group were offered 100% concentrate (2.93Mcal DE/kg, 13.78% CP in gestation and 3.01Mcal DE/kg, 15.61% CP during lactation). In another group, 20%～30% ryegrass was used to substitute for concentrate.Reproductive performance in sows and litter performance were determined, and economical benefit was analyzed.Substitution of concentrate with ryegrass at 20%～30% increased weaning piglets, and improved firstborn litter weight, weaning litter weight and average litter weight gain ($P$>0.05). Compared with the control, 20%～30% green forage substitution of concentrate decreased feed cost by 40.73 Yuan/head during a propagate period, and profitted 44.23 Yuan/head.
