Box 80208, Jeddah, 21589, Saudi Arabia Corn gluten meal (CGM) is a valuable by-product of corn wet milling process. The increment of this product production needs an evaluation to improve the utilization of CGM as a protein source in broiler diets. Three exp. were conducted to study the influence of replacing 0, 25, 50, 75 and/or 100% of CGM by soybean meal (SBM) protein. Within each level; two diet forms (mash or pellet); were used and supplemented with or without probiotics or phytase. Body weight, feed consumption, feed conversion, carcass characteristics, skin and leg color, plasma total protein, fat and cholesterol, tibia and manure ash, Ca and P, breast and thigh meat protein and fat were determined. Results showed that pelleting diets did not lead to improving in the utilization of CGM, while probiotics addition 0.1% can improve the utilization of CGM protein up to 75% replacement of SBM protein. Moreover, phytase supplementation of 500 FTU/ kg diet improved life performance and bone mineralisation. Neither breast thigh meat protein, fat nor cholesterol were affected by either CGM levels, or by diet type or the interaction. Probiotic and phytase supplementation has increased breast and thigh meat protein but has decreased fat and cholesterol content. From these results; it could be concluded that SBM protein can be replaced by CGM up to 75% in plant broiler chicks diets with an addition of 0.1% probiotic and 500 FTU/ kg diet phytase to improve the utilization of nutrient, minerals and amino acids.
