The poultry industry is rapidly growing in Pakistan and feed for broilers are going to be a big issue. A huge quantity of distillery yeast sludge (16,000 t/year), having high moisture content (85%) produced by different industries, is one of solutions regarding feeding issues in the broiler industry. To reduce moisture content, a dryer has been developed, and the comparative performance of distillery yeast sludge dryer with respect to a conventional dryer was evaluated. It was found that a distillery yeast sludge dryer gives the best nutritional characteristics, namely, moisture contents of 27.42%, protein contents of 22.42%, nitrogen contents of 3.02%, phosphorous contents of 3.6%, fat contents of 2.14%, potassium contents of 5.0%, ash contents of 39.93%, and fiber contents of 0.0031% of dried sludge for sample weight of 600 kg and drying for a period of 6h, resulting in the best quality of sludge to use as poultry feed and organic manure.
