Melamine residues in tissues of broilers fed diets containing graded levels of melamine

Energy utilisation and growth performance of chicken fed diets containing graded levels of supplementary bacterial phytase.

A total of 364 female Ross 308 chicks (1 d old) were used in the present study conducted in floor pens to investigate the effects of graded levels of supplementary bacterial phytase on dietary energy utilisation and growth performance. For this purpose, four maize-soyabean-based diets were offered to the birds from 0 to 21 d of age. These included a suboptimal P negative control (NC, 3.0 g/kg n...

Effect of phytase supplementation on performance of broilers chickens fed diets with graded levels of phosphorus and calcium

One possibility to measure the extra-phosphoric effect of exogenous phytase is to use a higher concentration of this enzyme in the diets not limiting in phosphorus, to be sure that any observed effect is not caused by an increase in phosphorus digestibility. However, it is important to know how the requirements of the bird relate to the phosphorus content of the basal diet, because when the bas...

Effects of Mega Doses of Phytase on Growth Performance, Bone Status and Nutrient Excretion of Broilers Fed Diets Containing High Levels of Rice Bran

Phytate in poultry rations containing rice bran (RB) critically reduce poultry performance while increasing N and P excretion. The objective of this study was to determine whether the anti-nutritive problems associated with higher inclusions of rice bran in poultry rations (up to 40%) could be mitigated with mega doses of phytase. Twenty days old male broiler chicks (n=180) in 60 floor pens wer...
