摘　　要：选24头33kg左右的“杜洛克×长白×太湖”三元杂交猪，分成4组，每组6头。研究了黑麦草替代10％（T1）、15％（T2）、20％（T3）的精料对生长肥育猪的生长性能的影响，结果表明：试验组T1、T2、T3猪的日增重分别比对照组（C）提高17．57％（P〈0．01）、13．03％（P〈0．01）和11．74％（P〈0．01），试验组T1、T2、T3猪的日增重组间差异不显著（P〉0．05）。用黑麦草替代10％-20％精料与饲喂精料相比，净增重可降低饲料成本在0．73-0．86元/kg之间，降幅在12．28％-14．50％。Choosed 24 ＂Duroc x Landrace x Taihu＂ hybrid pigs that was abont 33 kg, and divided them into 4 groups, each group of 6 pigs. Studied the effects of growing-finishing pigs productivity by using ryegrass instead of 10%（T1）, 15%（T2）, 20%（T3） concentrated feed, respectively. The results indicated that compared to the control group （C）, the ADG of the pigs of the experimental group T1,T2,T3 separately improved 17.57%（P〈0.01）, 13.03% （P〈0.01） and 11.74%（P〈0.01）. The differences of ADG between the experimental groups T1,T2,T3 was not obvious（P〉0.05）. Using ryegrass to replace 10% to 20% concentrated feed, compared to the feeding concentrate, net weight can reduce feed costs in 0.73 - 0.86 yuan/kg, drop in 12.28% - 14.50%.
