【摘要】：研究旨在探讨季节性冷刺激对育肥猪生长性能和采食行为的影响。选取60头(116±5)kg的育肥猪,随机分为5组,每组12个重复,每重复1头猪。试验从2015年10月24日到2015年11月17日,共24d。试验10~15d发生大幅度降温,猪舍内平均温度从14℃降至7℃,对猪群造成冷刺激。利用奥斯本种猪生长性能测定系统,统计育肥猪的生长性能和采食行为数据。结果表明:与降温前舒适期(0d)相比,急速降温期(10~15d)猪群平均日采食量和料重比显著升高,平均日增重显著降低(P0.05);急速降温期日采食次数、采食速度均显著高于降温前舒适期和降温后适应期,单次采食时间和单次采食量显著降低(P0.05)。综上所述,冷刺激降低育肥猪的生产性能,导致采食行为发生变化。
[Abstract]:The purpose of this study was to investigate the effects of seasonal cold stimulation on growth performance and feeding behavior of fattening pigs. 60 fattening pigs with 116 卤5)kg were randomly divided into 5 groups, 12 replicates in each group, and 1 pig per repeat. The experiment was conducted from October 24, 2015 to November 17, 2015. For a total of 24 days, the experiment was conducted for 10 to 15 days, and the average temperature in the pigsty dropped from 14 鈩，
