分别采用菜粕和血粉为主要原料,按照鲫鱼肌肉必需氨基酸(EAA)模式添加和倍量添加晶体异亮氨酸(Ile)配制饲料,和缺乏Ile的饲料对比进行养殖试验,测定了鱼体的生长速度和对饲料的利用效率。结果表明,菜粕饲料中添加游离Ile对鲫鱼生长没有明显促进作用,也没有提高饲料效率,但在血粉饲料中的添加显示了明显的促生长效果,饲料效率也获得提高。
Rapeseed meal and blood meal were used as the main raw materials respectively, according to the essential amino acid (EAA) model of Carassius auratus (EAA) and doubled the amount of Ile, and compared with the feed without Ile, Growth rate and feed efficiency. The results showed that addition of free Ile to rapeseed meal did not significantly promote the growth of crucian carp and did not improve the efficiency of feed. However, the addition of free Ile in rapeseed meal showed a significant growth promoting effect and feed efficiency was also improved.
