| Abstract | ||
| An experiment was conducted to study the effect of replacing soybean meal (SBM) with mix of corn gluten meal (CGM), sunflower meal (SFM) and distillers dried grains with solubles (DDGS) at (2.5, 5 and 7.5%, respectively) with different protein levels (21, 20 and 19%) at finisher diets on live performance and carcass traits of broilers. A total of 432 day old Cobb 500 chicks were randomly distributed into 6 treatments at (19-35) days of age, each with three replicates, each replicate contains 24 chicks. The six treatments were: 1) control 21% CP, 2) tested 21% CP, 3) control 20% CP, 4) tested 20% CP, 5) control 19% CP and 6) tested 19% CP. Control diets were based only on soybean meal (SBM) as a source of protein, while tested diets based on mix of (CGM, SFM and DDGS) beside SBM. At the end of experiment at 35 days of age, 5 broilers per treatment were slaughtered and evaluated for carcass traits. The results of this study have shown that feeding tested diets at 21 and 20% protein could be applied without any effect on performance or carcass traits when compared to the corresponding control diets. However, feeding 19% tested diet showed better performance than control 19% but with no significant difference between them. So, it can be concluded that mix of (CGM, DDGS and SFM) could be included up to 15% to replace soybean meal protein in broiler finisher diets at a CP level ranged between 19 and 21 %. | ||
