Two trials were conducted to determination of chemical composition and nutritive valueof grade 1 wheat middlings wastes and its suitable levels in broiler chick’s diets were investigated. Experiment 1 evaluated the chemical composition, and energy and protein content. The experiment2 was conducted by 400 day old unsexed Ross 308 chicken were housed in straw litter pens. Fiverations were used as a five treatments includes (0, 7.5, 15, 30 and 45%) of wheat middlings in broilerdiets. Four replicates with 20 birds were arranged in each. All of diets were Isoenergetic and isonetrogenous. The main 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 3225 kcal/ kg and 14% respectively. No significant differences were found in body weight (BW), feed intake (FI)and feed conversion ratio (FCR) and production index (PI) in the broiler's feeding trial and in bydifferent levels of wheat middlings(p>0. 05). There were significant variables in final weight. Thetreatments fed with 45% 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.
