Evaluation of using distellers dried grains with solubles (DDGS) in broiler diets
Abstract: The present work was conducted to evaluate Distillers Dried Grains with solubles (DDGS) as source of protein in broiler diets through determination of total protein efficiency (TPE), nutrient digestibility, and studying the effect of increasing DDGS levels in broiler diets on growth performance. carcass characteristics and economical efficiency. In this study 640 one-day old Hubbard chicks were randomly distributed into 8 treatments, with 4 replicates and 20 birds each in a completely randomized design. Four levels of DDGS and two levels of enzymes preparation were used in a 4 x 2 factorial arrangement. The DDGS levels were 0, 20, 40 and 60% as replacement for soybean meal.
A commercial enzyme preparation (Phyzyme® XP "phytase" with Avzyme® 1500) was added at 0 and 0.03% of the diet. Water and feed in mash form were offered ad-libitum during the experimental period which lasted for 6 weeks of age.
Results showed that there were no significant differences between DDGS and soybean meal diets on the average values of total protein efficiency (TPE) Also the average values of nutrient digestibility were not affected significantly (P<0.05) with increasing DDGS levels except for CP and CF values. Results observed that enzyme supplementation had no significant effect on the all nutrient digestibility. Results obtained indicated that feeding broiler chicks on diets containing different levels of DDGS up 10 60% as replacement for soybean meal with or without enzyme supplementation improved body weight, body weight gain and feed conversion values. No significant effect of DDGS levels, enzyme, or their interaction on the average values of carcass characteristics. Results also showed an improvement in the average values of net revenue, economical efficiency and relative economical efficiency due to feeding broiler chicks on diets containing graded levels of DDGS up to 60% as replacement for soybean meal with or without enzyme supplementation.
In Conclusion, use of DDGS at 40% with enzymes recorded the best results compared to other treatments, Whoever, the results obtained cleared that DDGS can be successfully fed at levels up to 60% as replacement for soybean meal in broiler diets without enzymes supplementation without adverse effect on their performance, nutrient digestibility and economical efficiency.
