Responses to the increasing levels of digestible arginine/kg of diet showed a quadratic effect for the consumption of feed and digestible lysine for hens fed

Reducing or increasing dietary digestible lysine levels 7.5% below or above the established requirements is not sufficient to cause significant changes in body composition or in

There was a quadratic effect (p<0.05) of digestible lysine levels on average body weight at 40 days of age, daily weight gain, and breast yield, and a cubic effect on

On the other hand, the density of pelleted diets was positively correlated with weight gain, energy efficiency, and protein efficiency, and inversely correlated with feed

The addition of organic selenium to the diet improves weight gain, feed conversion ratio, vitamin E deposition in the fillet, and the level of glutathione peroxidase in the

In this way, the results for final weight, protein efficiency rate, weight gain and feed:gain ratio in mojarra fed with a higher protein content reinforces the assertion

The results showed that feed consumption, feed conversion ratio, fish weight gain, specific growth rate, protein efficiency ratio and protein productive value

The following variables were determined: diet consumption (DC), apparent feed conversion (AFC), weight gain (WG), specific growth rate (SGR) and protein efficiency rate
