Nile tilapia (Oreochromis niloticus L.) apparent digestibility of diets containing (high and low) tannin sorghum and methionine
This study was carried out in order to evaluate the effects of two sorghum varieties (high and low tannin) and levels of methionine (0.0%, 0.60% and 0.90%) in Nile tilapia, Oreochromis niloticus L. (Perciformes, Cichlidae), diets on apparent digestibility of dry matter, crude protein and crude energ...

| Resumo: | This study was carried out in order to evaluate the effects of two sorghum varieties (high and low tannin) and levels of methionine (0.0%, 0.60% and 0.90%) in Nile tilapia, Oreochromis niloticus L. (Perciformes, Cichlidae), diets on apparent digestibility of dry matter, crude protein and crude energy. 100 fish were distributed in ten aquarium (250L). After a climatization period of three days, representative samples of feces were obtained daily until reach six replicates each treatment. The apparent digestibility coefficient was calculated based in chemical analysis of diets and feces to determine chemical composition and chromic oxide. It was concluded that for Nile tilapia the low tannin sorghum has similar apparent digestibility to corn and that the high tannin variety has significant lower apparent digestibility than corn and low tannin. The supplementation of methionine it is not enough to control the anti-nutritional effect of tannin. |
