Phytate and Phytase in Broilers --a Review
The vegetable feed ingredients used in the preparation of poultry feed contains nearly two thirds of the phosphorus as phytates. The phytates are not only indigestible /unavailable but also are known to interfere with the utilization of other nutrients. Apart from the anti-nutritional effects the phytates bind with other minerals and make them unavialble to the birds. One of the best ways to ov...
متن کاملSunflower Meal and Enzyme Supplementation in Diets of Broilers from 21 to 42 Days of Age
The objective of this study was to evaluate the performance of male broiler chickens in the period from 21 to 42 days of age fed diets with increasing levels of sunflower meal (SM) supplemented with an enzyme complex (EC). A total of 1920 animals of the Cobb strain were distributed in a randomized block design in a 4 × 3 factorial arrangement (four SM levels and three enzymes utilization types)...
متن کاملContribution of intestinal- and cereal-derived phytase activity on phytate degradation in young broilers.
There is little consensus as to the capability of poultry to utilize dietary phytate without supplemental phytase. Therefore, an experiment was conducted to examine the extent to which endogenous phytase of intestinal and cereal origin contributes to phytate degradation in birds aged 0 to 14 d posthatch. Ross 308 broilers (n = 720) were fed one of 4 experimental diets with differing dietary ing...

متن کاملComparison of Methodologies to Quantify Phytate Phosphorus in Diets Containing Phytase and Excreta from Broilers
The use of a suitable methodology to quantify the phytate phosphorus (Pphy) content in both the feed and the excreta from broilers is required to enable accurate calculation of the catalytic efficiency of the phytase supplemented in the feed. This study was conducted to compare 2 analytical methodologies (colorimetry and also high-performance liquid chromatography with a refractive index detect...
