quality of protein fractions, according to cornell net carbohydrate and protein system (cncps), and digestibility coefficients, using tilley and terry procedure, of the fresh and ensiled amaranth (amaranthus hypochondriacus) forage were assessed. the concentration of crude protein (cp) and true protein (tp) in the fresh forage, were respectively 116 and 70 g/kg of dm. soluble protein (sp) and a...

In this study the effect of different protein levels on reproductive performance of Channa striatus was conducted. Snakehead juveniles (65.5±0.2 g) were randomly distributed into nine homogenous groups of 75 fish each. Three isocaloric experimental diets differing in protein levels were prepared. The experiment lasted for 8 months and gonadosomatic index, absolute fecundity, egg diameter, numbe...
