夏季高温阶段微生物发酵床表层温度分布研究

Surface Temperature of Fermentation Bed in Hog Farms during Hot Summer Time

发酵床养猪是对环境友好的新型养猪技术,其中发酵床垫料表层温度的控制是猪养殖过程中一个关键因素。为了探讨夏季高温期间微生物发酵床表层温度的状态,本研究对微生物发酵床猪舍内部各个区域及其外部环境的表层温度进行测量分析,结果表明:猪舍内发酵床垫料区域(30.13±0.86)℃和非垫料区域如采食槽(30.58±1.09)℃、饮水槽(30.93±0.86)℃和猪舍走道(29.90±0.69)℃的表层温度不存在显著差异、而猪舍内部表层温度与外部温度[阴影区(35.25±2.70)℃、非阴影区(41.44±2.12)℃]则存在显著差异;不同猪养殖密度的发酵床垫料表层温度不存在显著性差异;在一定养殖密度范围内,猪舍排泄区和非排泄区的垫料表层温度不存在显著性差异。

Raising pigs on a microbial fermentation bed was a newly implemented and environmentally friendly approach. Temperature of the bed was critical for an appropriate operation. Thus, the surface temperature of the bedding materials, particularly in the heat of summer, was monitored. No significant temperature differences were found in the areas covered by the bedding material i. e. , （30.13±0.86）℃ or where no such coverage was used in the feeding troughs （30.58±1.09）℃, drinking troughs （30.93±0.86）℃ or aisles （29.90±0. 69）℃. On the other hand, the surface temperature of the beds inside the piggery was significantly lower than outside the construction i. e. , （35.25±2.70）℃ vs. （41.44±2.12）℃. And, within a certain range, an increased pig breeding density did not, nor did amount of pig excretion, seem to significantly affect the bedding temperature.
