Nutritional Balance of Broilers Fed Diets Containing Two Calcium Levels and Supplemented with Different Phytase Levels

The experimental design was a randomized 2 x 2 x 3 factorial arrangement (two breeds: Morada and Santa Inês; two concentrate supplementation levels: 0.5 and 1.5% of body weight;

Table 5 – Regression equations of weight gain and feed conversion ratio of broilers fed diets with increasing sunflower meal levels and supplemented or not with an enzyme

The immune response in young broilers supplemented with different levels of zinc oxide and zinc-methionine was evaluated and showed no effects of zinc level or source on the levels

Broiler performance significantly improved in grower phase (weight gain and feed conversion ratio) by enzyme supplementation, while the effect of sunflower meal was evident in

The following orthogonal contrasts were analyzed: contrast C 1 , comparing diets with reduced calcium (Ca) and phosphorus (P) levels supplemented or not with phytase; contrast C 2

The crude protein levels in the diets based on corn and soybean meal (formulated with lysine, methionine and threonine in a digestible basis) for growing pigs should be reduced from

Therefore, the objective of this work was to evaluate the effect of diets with reduced levels of crude protein, available phosphorus, and calcium, supplemented with phytase and

Thus, the objective of this work was to evaluate the effect of diets elaborated with reduced levels of crude protein and phosphorus, supplemented with phytase and
