    The aim of this experimental work was to evaluation of efficiency of dietary inclusion of SCY as replacement for fish meal or poultry meat by – product in broiler diet. A completely randomized design with five treatments, each with three replication of twelve chicks each was conducted from 7-49 day of age to investigate the effects of Saccharomyces cerevisiae yeast (SCY) as replacement with fish meal or poultry by – product protein on broiler performance. Treatments include: 1 control group 2 and 3: yeast in replace with 40 and 60 percent of fish meal protein 4and 5: yeast in replace with 40 and 60 percent of poultry by-product protein. Inclusion of SCY as fish meal replacement in two levels (treatment 2 or 3) didn’t have any negative effect on feed intake, weight gain or feed conversion ratio. Also dietary inclusion of SCY as replacement of poultry meat by-product (40% of poultry meat by-product proportion in diet) didn’t have any negative effect on performance. Only inclusion of 60% SCY as replacement for poultry meat by product had significant negative effect on performance includes feed intake, weight gain and feed conversion ratio (P<0.05).The results of this study indicated the use of SCY with 60 percent replacement of fish meal protein and poultry by-product protein can improve meat quality and broilers performance.
