240 laying birds were procured and distributed randomly into four treatments and four replicate (15 birds each) which was fed one of the following experimental diets containing different levels of probiotics (Biomin IMBO) for seven weeks. 1-Basel diet (control groups), 2-Basel diet + 250 g/t, 3-Basel diet +500 g/t, 4-Basel diet +750 g/t feed respectively. As results was revealed, feed efficiency were improved significantly throughout the production periods
