The study was conducted to determine the effect meat and bone meal (MBM) supplementation (added at 2.0, 3.5 and 5.0%) to broiler chickens diets on performance from 22 to 42 days of age. Twenty two day-old one thousand and two hundred unsexed broiler chickens (Ross-308) were distributed to four treatment groups. Six pens of 50 broilers (25 male+25 female) were fed each of the dietary treatments containing 0, 2.0, 3.5 and 5.0% meat and bone meal. Supplementation MBM up to 5% to broiler chickens diets did not significantly affect body weight, body weight gain, feed consumption, feed conversion rate, mortality. Body weight gain, feed conversion rate, mortality were 1.282 kg, 1.90, 2.79% for 5% meat and bone meal versus 1.273 kg, 1.83, 1.60% for the control at 22 to 42 days of age, respectively. Also, dietary treatments had no significant (P>0.05) effect on carcass yield when slaughtered at 42 d. The data showed that dietary meat and bone meal up to 5.0% can be used successfully for broiler chickens diets when diets formulated isonitrogenous and isocaloric. In this study, formulation of cost of meat and bone meal included diets at level of 2.0, 3.5 or 5.0% were cheaper 2.19, 3.65 and 4.49% than that of control diet containing no meat and bone meal, respectively.
