摘 要: | 综述了典型淡水肉食性鱼类大口黑鲈营养需要的研究进展。蛋白质的营养需要量>37%,以40%为宜;脂肪为7%~16%,7%~10%最佳;碳水化合物不宜超过20%。赖氨酸、蛋氨酸的需要量分别为4.9、1.9 g/100 g蛋白质。根据理想蛋白质模型推测,100 g饲料蛋白质含精氨酸6.31 g、组氨酸1.31 g、异亮氨酸2.59 g、亮氨酸5.02 g、蛋氨酸+半胱氨酸2.10 g、苯丙氨酸+酪氨酸4.38 g、苏氨酸2.74 g、色氨酸0.56 g、缬氨酸2.90 g蛋白质时,可满足大口黑鲈各生长阶段的必需氨基酸需要量。必需脂肪酸、维生素和矿物质需要量的研究暂未见有报道。根据对淡水鱼类必需脂肪酸需要量的已有报道,建议大口黑鲈饲料中n-3和n-6系列脂肪酸的含量在0.5%~1.0%,但有关脂肪酸、维生素和矿物质等定量需要尚需进一步研究。同时,需加强大口黑鲈对常见饲料蛋白源、脂肪源及糖源利用率的研究,结果可为高效人工饲料的研发提供必要的参考。

Abstract: | The nutrient requirements of Micropterus salmoides were reviewed in this paper.Dietary protein requirement of largemouth bass is no less than 37%,and the optimal level is 40%.7%~16% lipid can be included in the diet,but the optimal level is 7%~10%.Carbohydrate level should be no more than 20%.The reported values for dietary lysine and methionine were 4.9,1.9 g/100 g protein.The deduced requirement values of other essential amino acids by using the ideal protein concept were arginine 6.31 g,histidine1.31 g,i... |
