摘要
为了评价地道通风猪舍、自然通风类型猪舍和机械通风类型猪舍对冬季育肥猪舍环境和育肥猪生长的情况,选取36头40 kg生长猪随机分成3个处理组,试验期为24 d。结果表明:地道组猪舍内温度都较自然组和机械组高,而且,地道组日增重分别比自然组和机械组多93.91 g和56.5 g(P<0.001)。结果提示地道通风类型的猪舍提高了冬季猪舍环境温度,有利于猪生长。
In order to evaluate the effect of tunnel ventilation,natural ventilation and mechanical ventilation on environment and growth performance in fattening pigs in winter season,36 pigs with body weights around 40 kg were randomly divided into three treatment groups and tested for 24 d. The results indicated that the temperature of the tunnel group were higher than that in natural and mechanical groups and the average daily gain were increased 93. 91 g and 56. 5 g,respectively（ P〈0. 001）. Our experiment suggested that the tunnel ventilation type of piggery raising environmental temperature in winter and helpful to pig growth.
