Abstract

This study aimed to study the effect of adding distiller’s dried grains with solubles (DDGS) with enzymes on production efficiency. 250 broiler chicks (Ross 308) were raised from 0-42 days old, without distinguishing between males and females. During this study, 5 feed mixtures were formulated, consisting of yellow corn, soybean meal 46%, DDGS and other feed supplements. These mixtures were equal in terms of protein values ​​and other feed supplements and differed from each other by the presence of different proportions of DDGS, as they contained 5 levels of DDGS (0, 5, 10, 15 and 20%) with enzymes. The results of the experiment in the first week showed that the mixtures containing DDGS at (10, 15 and 20%) led to a decrease in the weight of the chicks. The groups that ate DDGS at a concentration of (0 or 5%) had a higher feed conversion ratio than the other groups. At the end of the experiment, the birds that ate DDGS (0, 5 or 10%) achieved a better feed conversion ratio, compared to the groups that fed DDGS at 15 or 20%. This study showed that the maximum level of DDGS used in starter mixes is 5% and can be increased to 10% during the growth and finishing period. We also found that carcass and breast dressing weights decreased when DDGS were added.
