Effects of graded levels of phytase supplementation on growth performance, serum biochemistry, tibia mineralization, and nutrient utilization in Pekin ducks
A total of 560 one-day-old Pekin ducks were randomly allocated to 7 treatments with 8 replicate cages of 10 ducks per cage. The treatments included a corn–rice bran–soybean meal–based diet with recommended nonphytate phosphorus (NPP) (0.40% for 1–14 D/0.35% for 15–35 D, positive control; PC), NPP-de...
