Effect of dietary energy levels, vitamin B5 supplementation and stocking density on Nile tilapia (Oreochromis niloticus) growth performance [electronic resource].

Includes reference.

A factorial design (2x3x2) was conducted for studying the effects of dietary energy levels, supplementation levels of vitamin B5 and stocking density on growth performance traits, chemical body composition and blood components of Nile tilapia. All fish were divided into two main groups. The 1st main gronp was fed on a diet containing 2900 kcal/kg and the 2nd main group was offered a diet with 3500 kcal/kg. Each main group was divided into 3 subgroups; the 1st was fed on a diet without supplementation with Pantothenic acid (vitamin B5), the 2nd and 3rd groups were fed on diets supplemented with 10 and 20 mg Pantothenic acid/kg diet, respectively. Within each sub-group, the fish divided further into 2 sub-groups; the Ist was stocked at 10 fish/aquarium and the 2nd was stocked at 20 fish/aquarium.
