摘要
为了比较发酵床与传统模式的饲养效果,选择日龄相近、生长发育良好的杜×长×大三元配套系商品猪分为小猪组和大猪组。小猪组36头,试验组和对照组各18头;大猪组32头,分为试验组和对照组各16头,分别在发酵床和传统模式两种环境中生长。结果表明:发酵床模式与传统模式相比,小猪和大猪的试验组日增重比对照组分别提高4.52%、16.73%;料重比分别降低3.16%、7.43%;传统模式舍内环境与发酵床模式差异不显著。总体分析采用发酵床技术饲养育肥猪,每头可多获利126.24元。发酵床养猪模式的饲养效果优于传统养猪模式的饲养效果。
The feeding effects of pigs housed in deep-litter system and conventional system were investigated in this study. 36 healthy small pigs （Duroc×Yorkshire× Landrace） were randomly divided into control group and experiment group with 18 each,and 32 large pigs （Duroc× Yorkshire×Landrace） were randomly divided into control group and experiment group with 16 each. Pigs were fed in deep-litter system and conventional system. In the feeding course , the feed-intake was weighed Once a month, harmful gases and analysis of benefit, the piggery temperature and relative humidity were measured daily . The results showed that under deep-litter system, the daily gain of both small and big pigs in experimental group increased by 4. 52%, 16.73% respectively than that of the control; F/G decreased by 3.16% and 7.43% respectively; The environment in traditional pig house has insignifi- cant difference with that in deep-litter system. The overall analysis reveals that if rasing pigs with deep-litter system, more benefits of 126.24 Yuan RMB would be reaped per pig. It＇s concluded that the feeding effect of deep-litter system is superior to the traditional one.
