Abstract
The experiment was carried out from October 14 through November 24, 2021, in a private farm next to Qamchughah hamlet in Dukan town, 15 kilometers from Sulaymani City. This study was conducted to determine effects of using organic acids to diet will impact physiological parameters and production efficiency of broiler chicks. From a total of 400 broiler chicks (ross 308), 42-one day chicks divided to 4 treatments (C, T1, T2, and T3), each of which had four replications. A diet free of organic acid served as a control. Organic acid was added to the treatments T1, T2, and T3 at rates of 200 mg, 300 mg, and 400 mg/kg of diet, respectively. From 0 to 42 days, the organic acid was introduced to the meal. Body weight gain in T1, T2, and T3 birds was significantly higher (P 0.05) than in the other groups (T1, T2, and T3). Although FCR was significant (P0.05) in weeks 4 and 5, it was not significant (P>0.05) in 6 weeks of age compared to treatment 1. With the exception of T2 in the fourth week, which was not significant (P>0.05), feed intake was significantly higher in weeks 4, 5, and 6. Non-significant (P>0.05) cholesterol level on the fourth week. Creatinine and calcium did not differ significantly (P>0.05) between weeks 4 and 6, however calcium did differ significantly (P0.05) from week 6. The uric acid had no significant (P>0.05) effects.
