Phosphorus retention from barley-type diets with different levels of endo-phytase in broilers
Original language description
The efficacy of low-phosphorus diets with 0.20% of available phosphorus and two levels of phytase on growth rate, feed conversion ratio and phosphorus retention was examined in broiler chickens using eight replicates per treatment. The diets contained 40% of spring barley with 201 or 305 phytase activity units per kg. Chromic oxide was included in the diets as an indigestible marker. Excreta were collected during four consecutive three-day balance periods from the 12th to the 23rd day of age. No difference was observed for body weight gain between the dietary treatment groups but feed conversion ratio was better (P < 0.05) when higher phytase barley was used. The contents of total phosphorus was 4.56 and 4.72 g/kg in low and high phytase diets, respectively. In spite of the higher level of phosphorus, the coefficient of apparent phosphorus retention was higher (P < 0.01) in higher than in lower phytase group. The retention of phosphorus increased (P < 0.01) with duration of feeding in both low-phosphorus dietary groups.
