Název v původním jazyce

The effect of non-phytate phosphorus and phytase levels on performance, egg and tibia quality, and pH of the digestive tract in hens fed higher-calcium-content diet

Popis výsledku v původním jazyce

The effect of three levels of non-phytate phosphorus (NPP) (3.0, 2.1, and 1.7 g/kg) and two levels of 3-phytase (F) (0 and 150 phytase units (FTU)/kg) together with a high dietary calcium concentration (approximately 41.0 g/kg) on the performance characteristics, egg quality, pH of the digestive tract, and tibia bone quality of ISA Brown hens housed in enriched cages was evaluated. The diets with 3.0 g/kg of NPP with and without F and 2.1 g/kg of NPP with 150 FTU of F significantly increased egg production (P = 0.022) and daily egg mass production (P = 0.030). A low level of NPP decreased (P < 0.001) the body weight of hens at the end of the experiment. The highest values of albumen height (P < 0.001), albumen index (P = 0.004), Haugh units (P = 0.001), and albumen percentage (P = 0.004) were associated with the diet with the low level of dietary NPP without F addition. The low level of NPP with 3-phytase increased the calcium and phosphorus contents in eggshells (P = 0.002 and P = 0.0
