Three studies on broiler chicks to evaluate feeding value of corn cobs (untreated and/or subjected to alkali, high temperature and pressure (HTP) and cellulase enzyme) were run. Effects of varying levels, treatments (chemical, physical), and pelleting on performance (voluntary feed intake, growth response, feed efficiency, dressing percentages, weights of some internal organs) and digestibility and availability of dry matter and crude protein, metabolizable energy and body nitrogen retained were determined. The optimum level of corn cob meal found was 12.5% of the ration. Alkali treatment, HTP, cellulase addition and pelleting do not warrant their use as no significant improvements were generally obtained. If, ever, additional expense incurred negates any advantage of these treatments over the untreated. A very minimal increase of 0.0024/kg feed by using 12.5% corn cob meal makes its use very feasible
