<b>Semen quality in Nile tilapia (<em>Oreochromis niloticus</em>), fed with diets containing different vitamin C levels</b> - doi: 10.4025/actascianimsci.v32i3.7836

Abstract

Vitamin C acts as cellular protection from damage by free radicals, and vitamin C supplementation is considered essential for most fish species, as they do not synthesize it due to the absence of enzyme L-gulonolactone oxidase. Thus, the effect of supplementation with 0, 75, 150 and 225 mg of vitamin C kg^-1 of ration was evaluated in the semen quality in Nile tilapia (Oreochromis niloticus). Seminal parameters were not influenced by vitamin C supplementation except progressive motility, which increased linearly with the addition of vitamin C. It was concluded that Nile tilapia reproducers should be supplemented with 225 mg vitamin C kg^-1 ration.
