摘 要:冬季低温饮水不利于断奶仔猪的生长发育。本试验设计了在规模化猪场保育猪舍适用的恒温饮水系统,实现饮水的恒温化,比较分析饮用温水的试验组与冷水对照组仔猪在生长性能和免疫水平上的变化。结果显示,与对照组相比,试验组仔猪饮水日均和昼夜水温均稳定于26℃左右(24.5~26.6℃);试验组温水的总菌和大肠杆菌数远低于对照组;试验组仔猪平均日增重较对照组提高4.15%(P<0.01),日均采食量较对照组提高7.76%(P<0.05),腹泻率仅为对照组的43%(P<0.01)。两组仔猪在IgG、IgM和IgA水平,以及猪圆环病毒和猪瘟病毒抗体水平上无明显差异(P>0.05)。上述结果说明,饮用温水对于断奶仔猪的生长性能有明显促进作用,对免疫水平无明显影响。Drinking cold water in winter is detrimental to the growth and development of post-weaning piglets.Thus,a system providing the piglets with warm drinking water at 26℃(ranging 24.5-26.6℃)in a scale-up swine farm was installed for the study.Changes on the growth and immunity of the piglets were monitored.The results indicated that the total bacteria and Escherichia coli counts in the warm drinking water for the treatment were significantly lower than those in the cold water for control.The average daily weight gain of the piglets in the treatment group was significantly higher than that of control by 4.15%(P<0.01).The daily feed intake of the treatment piglets was significantly higher than that of control by 7.76%(P<0.05).Whereas,the incidents of diarrhea in the treatment piglets were merely 43%of that incontrol group.There were no significant differences observed on the levels of IgG,IgM,IgA,porcine circovirus and classical swine fever virus antibodiesin the piglets between the treatment group and control(P>0.05).It appeared that the consumption of warm drinking water in cold weather could significantly improve the growth,without negatively affecting the immunology,of the post-weaning piglets.
