Efficacy of contrast levels of non-phytate phosphorus and Aspergillus niger phytase in hens fed wheat-maize-based diets
Original language description
A 2 x 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-maize-based diet. A significant effect of both NPP and F was found for the yolk colour (P = 0,016) and shell thickness (P = 0,038). The F supplement or higher level of NPP alone and in combination increased the value of the yolk colour and shell thickness. The supplementation of the basal diet with F significantly increased the laying performance, especially withregard to the egg weight and feed conversion ratio. The higher dose of NPP had a negative effect on the egg production, feed intake, and feed conversion ratio. The lower level of NPP (1,3 g/kg) decreased the internal egg quality and shell
