This study was conducted to determine effects of and a proper level of barley malt sprouts(BMS) addition as well as to develop an effective fermentation method when broiler litter(BL) was ensiled or deepstacked with 0 to 10% levels of BMS. Mixtures were ensiled or deepstacked for one month and physico-chemical analyses were made between before and after treatments. Addition of BMS up to 10% enhanced nutritional quality of either of ensiled or deepstacked BL mixtures. Especially, the quantity and quality of protein were improved with the addition of BMS to BL. However, the still high pH values after ensiling of various mixtures indicated that anaerobic fermentation did not effectively occur with the addition of up to 10% of BMS to BL and consideration of fermentation aids appeared to be necessary. For deepstacking, addition of BMS to BL increased internal peak temperature(from 56 to $70^{\circ}C$) of the stack, indicating that the added BMS to BL stimulated the degradative activity of fermentative microorganisms. The deepstacking method was more effective than the ensiling method for the manufacture of hygienical fred mixture with BL and BMS.
