Effects of α-Galactosidase Supplementation on Performance and Energy Metabolism for Broilers Fed Corn-non-dehulled Soybean Meal Diets*
To study the effects of α-galactosidase (α-Gal) supplementation on performance and energy metabolism, 216 Arbor Acres male broilers were placed in 36 cages of 6 birds each and allotted to 4 diets for 42 d, with 0-21 d as starter period and 22-42 d as grower period. The 4 diets were based on corn non-dehulled soybean meal in a 2×2 factorial arrangement, with 2 levels of α-Gal (0 vs. 60 U/kg feed...
متن کاملStarch digestibility, energy utilization, and growth performance of broilers fed corn-soybean basal diets supplemented with enzymes.
A study was conducted to evaluate the effects of dietary α-amylase and β-xylanase supplementation of corn-soy diets, formulated with or without supplemental phytase, on growth performance, energy utilization, and starch digestibility in broiler chickens. A total of 336 slow-feathering, Cobb × Cobb 500 male broilers were randomly distributed to 6 treatments having 8 replicates of 7 birds each. B...

متن کاملEnergy utilization and growth performance of broilers receiving diets supplemented with enzymes containing carbohydrase or phytase activity individually or in combination.
Energy utilization in broilers as influenced by supplementation of enzymes containing phytase or carbohydrase activities was investigated. Day-old male broilers (480) were allocated to four slaughter groups, thirty broilers in the initial slaughter group and 150 broilers in each of the final slaughter groups on days 7, 14 and 21. Broilers in each of the final slaughter groups were allocated to ...
متن کاملEffect 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...
