Abstract:

This study was designed to investigate the effect of novel bio-bedding under slatted floor (BBSF) system on duck house air quality and Muscovy duck production performance.A total of 6 000 Muscovy ducks with 30 days of age were randomly and equally allocated into 3 types of houses,which were BBSF,conventional floor bio-bedding (CFBB) and slated floor (SF) system houses,respectively.The concentrations of harmful gas,dust,airborne lipopolysaccharide (LPS) and microorganisms in house at 08:00,14:00 and 20:00 every 10 days were tested,and Muscovy duck production performances were determined.During experiment period,the concentrations of NH3,LPS,total aerobe,Escherichia coli,“Salmonella and Shigella” in BBSF were lower than that in CFBB (P<0.05) or SF (P<0.05) at 36,46,56 and 66 days of age,respectively,and PM10 concentration in BBSF was lower than that in CFBB (P<0.05) at 56 days of age.The concentrations of NH3,total aerobe,Escherichia coli,“Salmonella and Shigella” in BBSF were lower than that in CFBB (P<0.05) or SF (P<0.05) at 08:00,14:00 and 20:00,respectively,and LPS concentration at 14:00 and CO2 and LPS concentrations at 20:00 in BBSF were all lower than that in CFBB (P<0.05).Duck daily gain in BBSF were higher than that in CFBB (P<0.05),while livability and feed efficiency (P<0.05) in BBSF were also higher than that in CFBB and SF.The results indicate that,compared with CFBB or SF,BBSF is better in controlling house air environment and improving growing Muscovy duck health and production performance.
