Effects of Different Feeding Durations on Ileum Length and Weight and Basal Endogenous Loss of Phosphorus in Broiler Chickens Fed a Phosphorus-Free Diet

The study investigated the effects of feeding duration on length and weight ileum, basal endogenous loss (BEL) phosphorus (P) broiler chickens fed a P-free diet (PFD). A standard starter was to 384 birds for 15 days. On day 15, they were weighed randomly allocated one three treatment groups in randomized complete block design, with eight replicate cages per 16 cage. each group PFD 2, 3, or 4 There an increase growth performance (p < 0.05) as increased from 2 Although relative dry ileum (mg/100 g body weight) decreased linearly increased, amount dried ileal digesta (g/bird) not affected.
