Feed additives are incorporated in animal feeds for the purpose of improving rate of live weight gain and feed efficiency of the animals, and also for preventing and controlling diseases. Over the years, antibiotics has been used as feed additives. The massive use of antibiotics for disease prevention and growth promoter in animal production has been implicated in the emergence of antibiotic resistant pathogens and antibiotic residues in animal products. For this reason, certain regulatory bodies (such as the European Commission and United States Department of Agriculture) have banned their inclusion in animal feed. Thus, natural alternatives such as yeast culture that are safe, cheap and readily available to smallholder farmers, is an important strategy. Topics to be discussed in this review paper include; the feed additives used in animal nutrition, alternatives to antibiotics and yeasts as probiotics and its effects.
