断奶仔猪不同饲养工艺对保育期生产成绩的影响研究

Study on the Impact of Different Feeding Processes on the Weaned Pigs' Production Performance

为探讨断奶仔猪不同饲养工艺对保育期生产成绩影响,试验将川藏黑猪父母代仔猪35日龄断奶后继续放至产仔舍原圈饲养至双月龄作为试验组,将35日龄断奶后原圈饲养7 d后,由产仔舍转入保育舍饲养至双月龄作为对照组,比较两组仔猪在保育期的存活率及个体增重成绩,结果表明:试验组的断奶仔猪存活率高于对照组2.06个百分点,但差异不显著(P>0.05);试验组在保育期的个体增重比对照组高12.46%,且差异显著(P<0.05)。综上所述,产保一体的饲养工艺较传统饲养工艺更有利于断奶仔猪的生长。

To investigate the effect of different feeding processes on the weaned piglets＇ production performance,this experiment divided weaned pigs into two groups, then compared these two groups＇ survival rate and weightgain from weaned to two months old. We took the piglets which were kept in the original enclosure after weaningas the exprimental group, and we took the weaned pigs which were transferred intoa new enclosure 7 days afterweaning as the control group. The results showed that the experimental group＇s survival rate is 2.06 percentagepoints higher than the control group＇s（P〉0.05） and the experimental group＇s weight gain is 12.46% higher thanthe control group＇s （P〈0.05）. In summary, the weaned pigs had better be kept in original enclosure until twomonths old after weaning, this method is conducive to the growth of weaned piglets.
