Abstract

The histometry, organosomatic parameters and growth performance of African catfish, Clarias gariepinus fed with commercial probiotics, Lactobacillus pentosus supplemented diet was assessed in the present study. Six experimental diets were formulated, at different inclusion levels of Lactobacillus pentosus of 0, 102,104, 106, 108and 1010 cfu in T1, T2, T3, T4, T5 and T6 respectively. C. gariepinus were stocked into concrete tanks of 1.93 m by 1.93 m by 1.09 m. Each experimental diet was fed to three replicate groups of fish for 42 days. At the end of the feeding, histometrical parameters like mucosal fold length, mucosal fold breadth, mucosal fold area improved with increasing supplementation levels of L. pentosus. There was also significantly better P > 0.05 organosomatic parameters in all treatments with increasing level of supplementation. The best growth performance in term of specific growth rate (SGR) and feed conversion ratio (FCR) was observed in Treatment 3 as 10.49±0.23 and 1.56±0.22 respectively. The enhanced growth performance and histometry in fish fed diets with L. pentosus supplementation resulted in the best biological performance in African catfish at 1.0 g per 100 g of feed representing 104 cfu supplementation level. Therefore the present study shows that L. pentosus can be recommended as an important probiotic in aquaculture.
饲粮中添加益生菌对非洲鲶鱼Clarias gariepinus (Burchell, 1822)的组织学和生长性能的影响
本试验研究了非洲鲶鱼、加里平Clarias gariepinus在饲粮中添加商业益生菌和戊酸乳杆菌后的组织形态学、脏体参数和生长性能。分别在T1、T2、T3、T4、T5和T6配制6种不同添加水平为0、102,104、106、108和1010 cfu的戊酸乳杆菌试验饲粮。放养在1.93 m × 1.93 m × 1.09 m的混凝土罐中。每种试验饲料分别饲喂3个重复组,试验期42 d。结束的时候喂食,histometrical参数如粘膜褶皱长度、粘膜褶皱宽度、粘膜褶皱区域提高l . pentosus水平增加补充的。随着添加水平的增加,各处理的P >.05脏体参数也显著改善。在特定生长率(SGR)和饲料系数(FCR)方面,处理3的最佳生长性能分别为10.49±0.23和1.56±0.22。增强在食物喂养的鱼生长性能和histometry l . pentosus补充导致最好的生物性能在非洲鲶鱼每100克1.0 g代表104 cfu补充饲料。因此,本研究表明,戊酸乳杆菌可作为一种重要的益生菌推荐用于水产养殖。
