摘要 随机选取32头生长肥育猪,分别饲养在混凝土实体地面(对照组)和铺设微缝地板(试验组)的圈栏内,对各组猪栏内NH3和CO2浓度、猪的采食、饮水、躺卧、排泄、拱啃等行为以及猪的生产性能进行观察。结果表明:在第1、2周微缝地板栏内的NH3平均浓度显著低于实体地面栏内的浓度(P<0.05),第3周微缝地板栏内的NH3浓度呈现下降的趋势;微缝地板与实体地面栏内CO2平均浓度各周无显著差异,但均呈现降低趋势。猪的采食、饮水、躺卧行为时间没有显著差异(P>0.05),而排泄时间试验组显著低于对照组(P<0.05);同时,试验组肥育猪采食频率显著高于对照组(P<0.05);试验组肥育猪发生拱地的头数显著多于对照组(P<0.05),发生啃咬行为的头数显著低于对照组(P<0.05);同时,试验组肥育猪的平均日增重比对照组提高9.09%。
