Effects of Microbial Litter Amendments on Broiler Performance, Litter Quality and Ammonia Production Hinkle, Matthew (2011-02-22)The reuse of litter in broiler production can lead to litter pathogen buildup and high levels of ammonia in broiler housing, thus resulting in poor broiler performance. This study evaluated the effects of two microbial ...
