Abstract
The study was conducted in 2015 at the Animal Production Department, Faculty of Agriculture, Diyala University in Iraq to determine the effect of adding different concentrations of organic chromium picolinate as additives to Japanese quail diets. 90 birds at age of 14 days and were divided into three groups according to diet (30 birds for each treatment with ten birds for each replicate). First group (T1) were fed without adding chrome (as control), second group (T2) were fed with 250 μg chrome/kg, and third group (T3) were fed with 500 μg chrome/kg. The feed and water were added freely. Live weight, daily weight gain, feed consumption and feed conversion rate were measured weekly. At the end of the study, six birds from each group were slaughtered to calculate the dressing percentage. The difference between live weights was not significant (P≤0.05) except at age of 35 days, where T3 surpassed the control treatment significantly (P≤0.05). No significant effects were observed on the daily weight gain, daily average of feed consumption and feed conversion rate at different weeks, but T3 treatment surpassed the control treatment significantly (P≤0.05) in dressing percentage.
Key words: Japanese quail, Chrome organic, Dressing percentage.
