摘要
本试验选择杜洛克×长白杂交肥育猪２４头，在相同营养水平条件下进行试验，探索不同环境温度对肥育猪增重的影响。试验结果，试验Ⅰ、Ⅱ组舍内温度（１４．５℃、１０．５℃）均高，与最适温度（１５℃－２３℃）的基本接近。分别比对照组提高２８．９℃和２４．９℃（Ｐ＜０．０１）；日增重分别比对照组高出５８．５５％和４４．６５％（Ｐ＜０．０１）；每ｋｇ增重消耗饵饲料量分别比对照组减少３６．９％和３０．８％（Ｐ＜０．０１）。
In order to
study the effects of environmental temperature on daily gainof growing finishing pigs,24
selected growing finishing(Lxd)were raised in differenttemperature and same nutritional p1ane.
The results showed that temperature in pigstyof trial Ⅰ,Ⅱ increased 28.90℃,24.90℃(P<0.
01);daily gain 58. 55%,44. 65%(P<0.01)and quantity of feed consumption decreased 36.9%,
30,8%(P<0.01)comparedwith the control respectively.Trial Ⅰ,Ⅱ obtained higher
temperatrue(14.50℃,10,50℃),which were almost close to those obtained at the optimum
temperature(15-23℃)
