Abstract

Rising feed costs and competition for conventional feed ingredients such as maize and soybean meal have intensified the search for economical, and sustainable alternatives in poultry nutrition. Brewery waste, particularly brewers’ dried grains (BDG), has gained attention as a promising unconventional feed resource rich in crude protein, fermentable fibre, B-complex vitamins, and minerals such as phosphorus. A critical appraisal of existing studies indicates that BDG can partially replace conventional feed  ingredients  without  adversely  affecting  growth  performance,  feed  conversion ratio, carcass yield, or haematological and biochemical indices of broilers, provided inclusion levels remain within optimal limits. However, high fibre content, variability in nutrient composition, and susceptibility to microbial contamination constrain its wider adoption. Enzyme supplementation, proper drying, and blending with energy- rich ingredients can improve its digestibility and nutrient balance. Economic analysis consistently demonstrate reduced feed costs and improved profit margins with BDG inclusion, underscoring its potential for cost-effective and environmentally sound poultry production. Further research is warranted to standardize processing techniques, optimize inclusion levels, and ensure product safety and consistency across brewery waste sources.
