A Study on grade one Wheat Middlings Usage onTurkeys Performances.

ABSTRACT: Two trials were conducted to determination of chemical composition and nutritive value of grade 1 wheat middling wastes and its suitable levels in turkey diets were investigated. Experiment 1 evaluated the chemical composition, and energy and protein content . The experiment 2 was conducted by 160 day old unsexed white wide breast turkeys. Four rations were used as a four treatments includes (0, 10, 20,30%) of wheat middling’s in turkeys diets. Four replicates with 10 birds were arranged in each. All of diets were Is energetic and isoneerogenous. The experiment was started from 30 days of age to the 120 days of old. Experiment statistical was in complete random design (CRD), data analyzed by SAS program and means were examined by Duncan multiple test.Themetabolizable energy and protein content were 3220 kcal/ kg and 14.2% respectively. No significant differences were found in body weight (BW), feed conversion ratio (FCR) and body weight gain and cost of 1kg meat production in the turkey feeding trial and in by different levels of wheat middlings(p > 0.05).There were no significant variables in breast and thigh and abdominal fat and viscera percent of slaughtered turkeys too (p > 0.05).However, in this study, these variations did not significantly affect the performance of turkeys.It would suggested that 30% of wheat middlings in turkeyʹs ration could leads to decrease the ration price and approach more benefits for turkey industry
