Theses and Dissertations--Animal and Food Sciences
Two experiments were conducted to examine the effects of oil type, oil quality, phytase, and vitamin E (VE) supplementation in broiler chickens. Experiment 1 used 378-day-old male by-product Cobb breeder chicks with 9 treatments, 7 replicates, and 6 birds per replicate, structured as a 2x2x2+1 factorial arrangement of treatments for 14 days. The first 8 treatments were based on a marginally non-phytate phosphorus (NPP) deficient diet (0.31%), while treatment 9 was a positive control (PC) diet with adequate NPP levels (0.45%). There were 2 levels of phytase (0 vs 1000 FTU/kg), 2 levels of oil quality (fresh soy oil; peroxide …
