Pullets (19 wk of age) previously fed varying levels of aP (available P) with and without phytase (Natuphos) from Day 1 of age were used to determine the influence of 300 FTU phytase/kg diet on hen performance during Phase 1 (Week 21 to 36) and 2 (Week 37 to 48). At 19 wk of age, pullets were switched from developer diets to layer diets. The aP levels used in this portion of the study remained at 0.1, 0.2, 0.3, and 0.4% with and without phytase. These were the same levels fed in the starter and… CONTINUE READING
