Effect of straw size and microbial amendment of litter on certain litter quality parameters, ammonia emission, and footpad dermatitis in broilers

摘要: Abstract. This study was conducted to evaluate the impact of litter amendment (microbiological product – Micropan complex) and straw size (unchopped chopped straw) on pH, moisture level, ammonia emission, footpad dermatitis in broilers. A total 1200 1-day-old Ross 308 broilers were randomly allocated four treatments (2  ×  2 factorial arrangement), with replicates per treatment. Each replicate consisted 75 as-hatched birds pen. The first factor wheat (C) or unchopped (U) second (WM) without (OM) Micropan® (enzymatic bacterial Eurovix, USA). At 4, 5, 6 weeks trial, levels concentration, content, pH each pen measured. foot pad lesions evaluated at 21, 35, 42 days age. Broilers reared had significantly better leg condition as expressed by a smaller incidence severity dermatitis. value decreased quality improved application kept sixth week There no significant effect emission broiler housing.
