Effect of dietary available phosphorus and phytase on production performance of old laying hens and tibia bone quality
Background: Old laying hens are more prone to dietary calcium (Ca) and phosphorus (P) deficiencies as they absorb Ca and P less efficiently than younger hens. OBJECTIVES: In a 2×2 factorial design, the influence of diets with two levels of available phosphorus (AP) and phytase enzyme on the laying performance, egg quality and tibia bone characteristics of laying hens at their late 2nd producti...
متن کاملEffect of dietary phosphorus, phytase, and 25-hydroxycholecalciferol on broiler chicken bone mineralization, litter phosphorus, and processing yields.
Three floor pen experiments (Exp) were conducted to evaluate low nonphytin P (NPP) concentrations and the NPP sparing effect of phytase (PHY) and 25-hydroxycholecalciferol (25D) on bone mineralization, bone breaking during commercial processing, litter P, and water-soluble P (WSP) concentrations. Tested treatments (TRT) were control, National Research Council NPP; University of Maryland (UMD) N...
متن کاملGrowth Performance, Phosphorus Balance, and Bioavailability of Phosphorus in Pigs Fed High Available Phosphorus Corn and Phytase
Phytase has been shown to consistently improve the bioavailability of phytate phosphorus for pigs. However, only about 60 to 70% of the phytate P in a corn-soy diet is made available when supplemented with an optimal phytase dose. The use of high available P (HAP) should provide an additional strategy for improving the bioavailability of phytate P in pigs. In experiments 1 and 2, growth perform...
متن کاملThe effects of various dietary levels of phytase and available phosphorus on performance of laying hens.
Data previously obtained from our laboratory indicated that addition of 300 U of phytase/kg diet supported optimal long-term performance of laying hens (20 to 70 wk) fed a corn-soybean meal (SBM) diet containing 0.10% available phosphorus (AP). Our primary objective was to determine if a phytase level lower than 300 units/kg is adequate for a commercial strain of Single Comb White Leghorn layin...
