在大西洋鲑鱼的膨化饲料中，研究了用豆粕 (SB) 或窄叶羽扇豆 (LP) 或豌豆 (PP) 制成的浓缩蛋白替代鱼粉蛋白。使用含有每种植物粉的挤压饲料喂养鲑鱼（47 克）63 天，以替代 25% 和 33% 的鱼粉蛋白质，并与营养均衡的对照和商业鲑鱼饲料配方（在相同条件下挤压）进行比较。对照组和含有植物蛋白的饲料之间的体重增加没有显着差异。在两次更换时，商业Leed产生的增重显着高于对照饲料和LP。水平。 LP 的饲料消耗量明显较高，为 33%，但其他饲料之间没有其他显着差异。 PP 和 SE 的饲料效率 (FER) 和生产蛋白值 (PPV) 最高，且不受添加水平的影响，而 LP 在 33% 的添加水平下，饲料效率比 (FER) 和生产蛋白值 (PPV) 显着较低。增重和饲料效率比数据表明，豆粕和豌豆浓缩蛋白最有潜力替代膨化鲑鱼饲料中至少 33% 的鱼粉蛋白，而羽扇豆浓缩蛋白在较高含量时利用率较差。这些结果支持使用加工植物粉作为大西洋鲑鱼膨化饲料中鱼粉的重要替代蛋白质来源。 (C) 2000 Elsevier Science B.V. 保留所有权利。
The replacement of fish meal protein with soybean meal (SB) or protein concentrates made from narrow-leafed lupin (LP) or field peas (PP) was investigated in extruded feeds for Atlantic salmon. Salmon (47 g) were fed for 63 days on extruded feeds containing each of the plant meals to replace 25% and 33% of the fish meal protein and performance compared against a nutritionally balanced control and a commercial salmon feed formulation (extruded under the same conditions). There were no significant differences in weight gain between the control and feeds containing the plant proteins. The commercial leed produced significantly higher weight gain than the control feed and LP at both replacement. levels. Feed consumption was significantly higher for LP at 33%, but there were no other significant differences between the other feeds. Feed efficiency ratio (FER) and productive protein value (PPV) were highest for PP and SE and not affected by inclusion level, whereas they were significantly lower for LP at 33% inclusion. The weight gain and feed efficiency ratio data showed that soybean meal and pea protein concentrate had the best potential for replacing at least 33% of the fish meal protein in extruded salmon feeds and that lupin protein concentrate was less well utilised at the higher inclusion level. These results support the use of processed plant meals as important replacement protein sources for fish meal in extruded feeds for Atlantic salmon. (C) 2000 Elsevier Science B.V. All rights reserved.
