民猪与长白猪哺乳仔猪腹泻程度的差异及其对生产性能的影响

摘要

The experiment studied effect of diarrhea on growth and development of suckling piglets in two breeds. Min pig and Landrace sulking piglets were divided into health, slight, moderate and severe diarrhea based on diarrhea degree. And analyzed difference of diarrhea, daily gain and relative growth rate (effective index of weight gian, which is the gain of per unit weight in unit time) in different groups of these two breeds. The results showed that Landrace piglets reached diarrhea peak earlier and the diarrhea rate was higer than those of Min pig piglets (P0.05).%试验将民猪与长白猪哺乳仔猪按腹泻程度划分为健康、轻度腹泻、中度腹泻和重度腹泻组，分析品种间腹泻程度的差异及不同组别日增重和相对生长率（体重增长的有效指数，即单位时间单位体重的重量增加）差异，研究腹泻程度对两品种哺乳期仔猪生长发育的影响。结果表明，长白仔猪较早进入腹泻高峰期，腹泻率显著高于民猪仔猪（P0.05）。
