| 摘 要： | 将270尾平均体重为4g的健康尼罗罗非鱼按饲养试验要求分为3组,每组3个重复,每个重复各30尾,试验1组和2组分别在基础日粮中添加0.26%L-赖氨酸盐酸盐和0.39%L-赖氨酸硫酸盐,按产品中的赖氨酸含量计算,两组赖氨酸含量均为0.2%。饲养56d结果表明,与基础日粮组相比,添加L-赖氨酸硫酸盐使罗非鱼日增重、特定生长率、蛋白质效率、干物质和粗蛋白消化率分别提高了20.93%(P<0.05)、7.14%(P<0.05)、21.43%(P<0.05)、7.51%(P<0.05)和4.78%(P<0.05);L-赖氨酸盐酸盐也有提高生长性能和饲料养分表观消化率的趋势,但差异不显著(P>0.05)。 |

| Abstract: | A total of 270 Nile tilapia at an average initial body weight of 4.0 g were used to investigate the effects of Lys·H2SO4 on the growth performance and apparent digestibility. Fish were allocated to three dietary treatments (three replicates of 30 fish/tank) for 56 days. The dietary treatments were: control, control+0.26% Lys·HCl; control +0.39% Lys·H2SO4. The results showed that as compared with control, supplementation with Lys·H2SO4 increased average daily weight gain, specific growth rate, protein efficiency ratio,apparent digestibility of dry matter and crude protein 20.93% (P<0.05), 7.14% (P<0.05), 21.43% (P<0.05), 7.51% (P<0.05) and 4.78% (P<0.05), respectively. While fish fed with Lys·HCl had slightly greater growth performance and apparent digestibility than the control, but the tendency was not significant(P<0.05). |
