Effect of adding a microbial phytase and polyethylene glycol to sorghum based diet on growth performance and meat oxidative stability of broiler chickens

This experiment was conducted to investigate the effect of a microbial phytase and polyethylene glycol (PEG) supplementation in sorghum based diet on performance and meat oxidative stability of broiler chickens. A total of 400 one-day old Ross 308 chicks were used by employing a completely randomized design with 5 treatments and 4 replicates. Treatments including a corn based diet with no additive (control), sorghum based diets with no additive or with phytase (500 FTU/kg), PEG (1 g/kg) or phytase PEG were fed to birds for a period of 42 days. Digesta and carcass were sampled on day 24 following the slaughter. According to the results, a similar weight gain for chickens on sorghum based diet with no additive (2410.3 g) and control (2442.5 g), and an improved weight gain for those received the additives was observed (P
