<b>Replacement of corn by sorghum silage with low and high tannin contents in diets for juvenile Nile tilapia (<em>Oreochromis niloticus</em>)</b>- DOI: 10.4025/actascianimsci.v25i2.1989
Abstract
This work was carried out to evaluate the replacement of corn by sorghum silage as an energy source for juvenile Nile tilapia, Oreochromis niloticus L. (Cichlidae). Three isocaloric (3000kcal of digestible energy) and isoproteic (28% of crude protein) practical diets were formulated. Corn meal was totally substituted by low (0.44%) (LTSS) and high (1.14%) (HTSS) tannin contents silage sorghum. Fish (55.09 ± 0.94g) were reared in fiberglass tanks (1000L) and hand-fed with experimental diets until reach they satiation, three times a day during 67 days. Feed conversion, protein efficiency ratio, hepatosomatic index, visceral fat and survival ratio of fish fed with the diets were not significantly different. Weight gain of fish fed with LTSS diet was significantly higher than those fed with corn and HTSS diets. Fish fed with LTSS diet had significantly higher feed intake than fish fed with corn and HTSS diets. Results indicate that a 44% inclusion of silage sorghum in the diet can support normal growth of the juvenile Nile tilapia with the potential for substituting corn.Downloads
