الملخص EN

The aim of the study was to determine the effect of dietary supplementation of mixing of organic acids (Propionic acid, Fumaric acid, Acetic acid, and Lactic acid) on the performance of broiler chicken.

240 one day old Male chicks (Ross 308) were used in this study and distributed randomly into four treatments by three replicates per each treatment (20 chicks in each replicate).

The diets of second, third and fourth treatments were supplemented with 0.2% , 0.4% and 0.6% from mixing of organic acid respectively and remained First treatment without supp- lementing as a control treatment.

The results showed the significant increase (P≤0.05) in the second and third treatments in the body weight and no significant differences in weekly weight gain between treatments.

Also there were significant improving (P≤0.05) in feed conversion ratio, dressing percentage, weekly feed intake and accumulated feed consumption in all treatments comparison with control as well as there were significant differences (P≤0.05) in the mortality percentage, Production Index and Economic Figure between treatments and control.

The results indicated that the organic acid supplementation at levels (0.2 % and 0.4%) had a beneficial effect on the performance of broiler chicken.
