摘 要:为了探究夏季发酵床结合网床养鸭模式对舍内环境质量和肉鸭生产性能的影响,为发酵床养殖模式在南方地区推广提供理论依据,比较分析了发酵床平养、网床架养和发酵床结合网床架养3种养殖模式对鸭舍内温度、湿度、粉尘、有害气体、微生物以及番鸭生产性能的影响。结果显示,在整个试验期间,大部分日龄发酵床结合网床架养的舍内NH3、CO2、PM10、总菌、大肠杆菌、沙门氏菌+志贺氏菌浓度低于网床架养或发酵床平养(P<0.05)。舍内温度、湿度、内毒素和PM2.5浓度在大部分日龄3种养殖模式间差异不显著(P>0.05)结合网床架养。发酵床结合网床架养模式的公番鸭、上市体质量、上市率均高于发酵床平养(P<0.05),料质量比低于网床架养和发酵床平养(P<0.05),发酵床结合网床架养母番鸭上市体质量、日增质量均高于发酵床平养(P<0.05),料质量比低于网床架养和发酵床平养(P<0.05)。可见,南方夏季高温高湿季节发酵床结合网床养鸭模式比单纯的发酵床养殖或网床架养模式能更好地改善舍内空气环境质量以及提高番鸭健康和生产性能。To investigate the influence of novel bio-bedding under slatted floor( BBSF) system on duck house air quality and Muscovy duck production performances in summer the novel BBSF system in Southern China,air quality parameters and duck growth performances were measured and compared in BBSF system,conventional bio-bedding( CBB),and slatted floor( SF) system. During the experimental period,the concentrations of duck house NH3,CO2,PM10,total bacteria,Escherichia coli,Salmonella + Shigella in BBSF system were lower than those in SF( P < 0. 05) or CBB system( P < 0. 05).Temperature and relative humidity,and the concentrations of LPS and PM2. 5 were close in the three types of duck houses( P > 0. 05). The PM2. 5 concentrations at 31 and 51 days after birth( P < 0. 05),temperature at 20∶ 00,and LPS concentration at 71 d after birth were lower in BBSF system( P < 0. 05). Duck daily gain,market weight and market qualifying rate in BBSF system were higher than those in CBB( P < 0. 05) or SF system( P < 0. 05). However,the ratio of feed to gain in BBSF were lower( P < 0. 05). The results indicate that,compared with either CBB or SF system,the BBSF system outperformed in improving duck house air environment,duck health condition and growth performances in summer.
