为研究日粮中不同比例花生粕替代豆粕对草鱼生产性能的影响，试验将4800尾体重为250 g左右草鱼随机平均分为4组，每组3个重复，每个重复400尾鱼，试验在网箱（4 m ×4 m ×3.0 m）中进行，持续90 d。对照组日粮中豆粕比例为16%，各试验组以等量花生粕分别替代对照组日粮中25%、50%、75%的豆粕。结果表明：花生粕替代75%豆粕显著降低了草鱼种的增重率（P＜0.05）、显著提高了饵料系数（P＜0.05），花生粕替代50%和25%豆粕，草鱼增重率和饵料系数与对照组无显著差异（P＞0.05）。花生粕替代豆粕对草鱼体成分影响不显著（P＞0.05），75%替代组草鱼肥满度显著降低（P＜0.05）。由此可见，本试验条件下，草鱼饲料中花生粕替代豆粕的比例为50%，即添加量为8%不影响草鱼生长性能。
為研究日糧中不同比例花生粕替代豆粕對草魚生產性能的影響，試驗將4800尾體重為250 g左右草魚隨機平均分為4組，每組3箇重複，每箇重複400尾魚，試驗在網箱（4 m ×4 m ×3.0 m）中進行，持續90 d。對照組日糧中豆粕比例為16%，各試驗組以等量花生粕分彆替代對照組日糧中25%、50%、75%的豆粕。結果錶明：花生粕替代75%豆粕顯著降低瞭草魚種的增重率（P＜0.05）、顯著提高瞭餌料繫數（P＜0.05），花生粕替代50%和25%豆粕，草魚增重率和餌料繫數與對照組無顯著差異（P＞0.05）。花生粕替代豆粕對草魚體成分影響不顯著（P＞0.05），75%替代組草魚肥滿度顯著降低（P＜0.05）。由此可見，本試驗條件下，草魚飼料中花生粕替代豆粕的比例為50%，即添加量為8%不影響草魚生長性能。

A 90-day feeding experiment was conducted in floating cages (4 m × 4 m × 3.0 m) to determine the po-tential use of peanut meal as a partial replacement of soybean meal in diet for grass carp with an initial average weight of about 250 g.Diets were formulated to include 0.25%,50%,75%of soybean meal being substituted by peanut meal with ly-sine supplementation.The results showed that:weight gain rate decreased significantly (P < 0.05) when the replacement level was 75%,and feed coefficient increased significantly (P < 0.05).Compared with control group,weight gain rate and feed coefficient of 25%and 50%replacement groups showed no significant difference.There were no significant differences in the moisture,lipid,crude protein and ash content of whole body among all groups and relative fatness of 75% replace-ment group decreased significantly (P < 0.05).Results of this trial indicated that the optimum level of soybean meal re-placement with peanut meal was 50%,on the basis of maximum weight gain.
