Usage of brewer’s yeast (Saccharomyces cerevisiae) as a replacement of vitamin and trace mineral premix in broiler diets

Some of the major issues faced by the poultry industry are about; improving efficiency of production, reducing environmental pollution resulted from litter and reducing food cost. In general, to meet these challenges, series of attempts have been made by researchers. Some of them are inclusion of food additives to improve growth performance, reduction of specific nutrient concentration or manipulation of nutrient utilization such as trace mineral nutrition to reduce food cost and nutrient excretion. The general consensus is that these nutrients may be omitted from the diet for various times of periods before slaughter without any significant effects on performance parameters and carcass traits [22-24].
