Abstract

A total of 125 day-old Arbor Acre broiler chickens were fed broiler starter till day 20. On day 21, the chicks were weighed and allotted to 5 treatments with 5replicates of 5 birds each in a randomized complete block design. The treatments comprised a positive control (PC, T1) without cottonseed meal (CSM) and four CSM-based semi-purified diets, negative control (NC, T2), NC+vitamin D3-10,000 IU/Kg (T3), NC+phytase (T4) and NC+phytase+vitamin D3 (T5).Titanium dioxide(TiO2) (5 g/Kg) was included as marker. On day 28, the birds were killed and digesta from the 2/3rd of the ileum collected. Digestible P was significantly (p<0.05) improved for birds on T5 when compared with the other four diets. Digestible P in T4 did not differ (p>0.05) from the birds on T1.Ileal digestible phosphorus (IPD) significantly (p<0.05) reduced with a corresponding increase in the percentage apparent phosphorus digestibility(APD) in T3, while T4 and T5 did not differ from T1 in the two parameters. It can be concluded that phytase and vitamin D3 supplementation on cottonseed meal improved digestible P in broiler chickens.
