A Study On Wheat Middling’s Usage On Broilers Performances

Two trials were conducted to determination of chemical composition and nutritive value of grade 1 wheat middlings wastes and its suiTable levels in broiler chicks diets were investigated. Experiment 1 evaluated the chemical composition, and energy and protein content . The experiment 2 was conducted by 200 day old unsexed Cobb 500 chicken were housed in straw litter pens. Five rations were used as a five treatments includes (0, 10, 20, 30 and 40%) of wheat middlings in broiler diets. Four replicates with 10 birds were arranged in each. All of diets were Isoenergetic and isonetrogenous. The experiment was started from 14 days of age to the slaughter weight. Experiment statistical was in complete random design (CRD), data analysed by SAS program and means were examined by Duncan multiple test. The metabolizable energy and protein content were 3220 kcal/ kg and 14. 2% respectively. No significant differences were found in body weight (BW), feed intake (FI) and feed conversion ratio (FCR) and production index (PI) in the broilerʹs feeding trial and in by different levels of wheat middlings(p>0. 05). There were significant variables in final weight . The treatments fed with 40% wheat middlingss have had less weight than others (p<0. 05). There were no significant variables in breast and thigh and abdominal fat and viscera percent of slaughtered broilers too (p>0. 05). However, in this study, these variations did not significantly affect the performance of broiler chickens. It would suggested that 30% of wheat middlings in broiler ration could leads to decrease the ration price and approach more benefits for poultry industry
