Effects of phytase B on laying performance, eggshell quality and on phosphorus and calcium balance in laying hens fed phosphorus-deficient maize-soybean meal diets
A study was conducted to evaluate the effects of dietary supplementation of phytase B (product of the Aspergillus niger phyB gene expressed in Trichoderma reesei) on feed intake, laying performance, eggshell quality, and on phosphorus and calcium balance in laying hens. Seventy-two, 40 weeks old Hy Line Brown hens were fed for 14 weeks the following four phosphorus-deficient (0.12% nonphytate p...
متن کاملEfficacy of contrast levels of non-phytate phosphorus and Aspergillus niger phytase in hens fed wheat-maize-based diets
A 2 × 2 factorial design experiment examined the effect of dietary non-phytate phosphorus (NPP) (1.3 and 4.0 g/kg) and 3-phytase (F) (0 and 150 FTU/kg) on the performance indicators of hens, physical parameters of eggs, phosphorus (P) content of the eggshells, and the pH of the digestive tract of laying hens. Two hundred and forty hens (ISA Brown) were housed in enriched cages and fed a wheat-m...
متن کاملEffect of Suboptimal Levels of Non-Phytate Phosphorus and Exogenous Phytase on Precaecal Digestibility of Phosphorus and Calcium in Laying Hens
Musilova A., Lichovnikova M., Kupcikova L., Anderle V. (2017): Effect of suboptimal levels of non-phytate phosphorus and exogenous phytase on precaecal digestibility of phosphorus and calcium in laying hens. Czech J. Anim. Sci., 62, 473–481. The precaecal digestibility of phosphorus and calcium in laying hens was evaluated at two dietary levels of non-phytate phosphorus (NPP; 1.58 and 2.03 g/kg...
متن کاملPhosphorus Partition in the Blood Serum of Laying Hens*
Much work has been done during recent years in investigating the calcium partition in the blood of laying hens. From this work an attempt has been made to determine the nature of the non-diffusible calcium. Although Laskowski (1) and Benjamin and Hess (2) investigated the partition of inorganic phosphorus in connection with the study of calcium in the serum of the laying hen, little has been do...
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...
