摘要
用鱼粉作饲料蛋白源配制饲料.蛋白质、醣、维生素和矿物质含量适宜,用大豆油调节饲料中的脂肪梯度,研究脂肪含量对长吻鮠鱼种生长的影响.结果表明,长吻鮠鱼种饲料中适宜的脂肪含量为6～12%,最佳值是9.95%.饲料中的脂肪含量对鱼肉和肝脏的生化组成有一定的影响.
An analysis was conducted on the effects of fat content in feeds on the growth of the Leiocas-sis longirostris fingerlings. Tested feed contained medium contents of protein, carbohydrate, vitamin and mineral salts but the fat added by gradient the fish meal used as the source of ptotein and fat the soybean oil as the source of fat. A parabolical curve was obtained from the study which indicates that the suitable fat level in feed should be 6-12% and the optimum requirement was 9.95%. Two experiments were carried out at fingerling stage and tbeir results were roughly similar. The fat content in feed directly affacts thd biochemical composition of fish muscle and liver.
