【摘要】：研究旨在探討季節(jié)性冷刺激對育肥豬生長性能和采食行為的影響。選取60頭(116±5)kg的育肥豬,隨機分為5組,每組12個重復(fù),每重復(fù)1頭豬。試驗從2015年10月24日到2015年11月17日,共24d。試驗10~15d發(fā)生大幅度降溫,豬舍內(nèi)平均溫度從14℃降至7℃,對豬群造成冷刺激。利用奧斯本種豬生長性能測定系統(tǒng),統(tǒng)計育肥豬的生長性能和采食行為數(shù)據(jù)。結(jié)果表明:與降溫前舒適期(0d)相比,急速降溫期(10~15d)豬群平均日采食量和料重比顯著升高,平均日增重顯著降低(P0.05);急速降溫期日采食次數(shù)、采食速度均顯著高于降溫前舒適期和降溫后適應(yīng)期,單次采食時間和單次采食量顯著降低(P0.05)。綜上所述,冷刺激降低育肥豬的生產(chǎn)性能,導(dǎo)致采食行為發(fā)生變化。
[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 鹵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，
