Effect of exogenous phytase on egg quality in laying hens

Popis výsledku v původním jazyce

An experiment was conducted to determine the effect of different levels of exogenous phytase on egg quality in laying hens fed diets with low levels of only plant original phosphorus. Twenty four Lohmann Brown hens at 31 weeks of age were housed in individual cages. In total three experiments were successively carried out with the same laying hens. In all three experiments the same diet with the same content of nutrients were always used. The control diet contained no exogenous phytase. Experimental diets differed in the level and sources of exogenous phytase. Eggs were collected daily during period of the experiment to measure egg quality. Measurement of physical parameters such as egg weight and strength of eggshell were performed daily. Shell weightand shell thickness were determined after washing and drying of shells. The shell thickness was evaluated using the micrometer. Shell proportion was calculated. The addition of phytase(150, 200, 250 and 300 FTU per kg diet) did not affec
