Abstract:

本试验旨在研究湿热环境对自由采食情况下生长育肥猪采食行为的影响。试验选取117头平均体重为(30.26±2.19)kg的健康生长猪,随机平均分到9个测定站,每个测定站采用全自动种猪生产性能测定系统和自动温湿度记录仪分别对采食行为和舍内温湿度进行记录。结果表明:生长育肥猪采食行为表现出明显的昼夜节律变化规律,06:00—09:00和15:00—19:002个时间段内的采食量、采食次数、采食时间显著高于21:00—04:00(P<0.05),其采食行为的52%以上都发生在这2个时段;温度、相对湿度及其互作能极显著影响生长育肥猪的单位体重采食量、采食时间(P<0.01),温湿指数的增加能显著降低单位体重采食量(P<0.05)。综上,湿热环境对生长育肥猪的采食行为有显著影响;其采食行为呈现昼夜节律变化。
