摘　　要：为研究果寡糖对育肥猪生长性能和养分表观消化率的影响,本试验选用200头健康育肥猪为研究对象,共分为4组,每组5个重复,即5栏,每个重复(栏)10头,对照组饲喂基础日粮,试验组分别在基础日粮中添加0.1%、0.5%和1%果寡糖,试验为期40 d。试验结果表明,添加果寡糖对育肥猪的采食量没有显著影响,但是显著增加了育肥猪的平均日增重,降低了料重比和腹泻率,添加0.1%、0.5%和1%果寡糖的育肥猪平均日增重比对照组分别显著提高9%、24%和23%(P<0.05),料重比分别显著降低9%、20%和19%(P<0.05),添加不同比例果寡糖的处理育肥猪的前期和后期的腹泻率均显著低于对照组(P<0.05);同时,添加不同比例果寡糖会显著提高育肥猪空肠的消化酶活性(P<0.05),肠道胰蛋白酶、脂肪酶和淀粉酶活性随着添加比例的增加消化酶活性增加,但添加0.1%果寡糖处理的育肥猪的消化酶活性与对照组相比差异不显著(P>0.05),添加1%果寡糖处理的育肥猪肠道消化酶活性最高;因此,添加不同比例果寡糖显著提高了育肥猪对干物质、粗纤维和粗脂肪的消化率,其中,添加0.5%和1%果寡糖处理的育肥猪对干物质、粗纤维和粗脂肪的消化率与对照组相比增幅分别为9%~10%、20%~26%和14%~19%(P<0.05),而对粗灰分和粗蛋白质的消化率无显著影响。综上所述,在日粮中添加0.5%~1%含量的果寡糖可以显著提高育肥猪肠道消化酶活性,增加对养分的表观消化率,从而提高饲料转化率,提高生长性能。In order to study the effects of fructo-oligosaccharides on growth performance and apparent nutrient digestibility of pigs,200 healthy pigs were selected as the research object,and four treatments were designed,with 5 repeats in each group,and 10 in each replicate.The experimental group was fed with basal diet with 0.1%,0.5%and 1%fructo-oligosaccharides respectively for 40 days.The results showed that the addition of fruit oligosaccharides had no significant effect on the feed intake of pigs,but significantly increased the average daily gain and decreased the feed gain ratio and diarrhea rate of pigs.Compared with the control group,the average daily gain of pigs supplemented with 0.1%,0.5%and 1%fruit oligosaccharides increased by 9%,24%and 23%,respectively,and the feed gain ratio decreased by 9%,20%and 19%,respectively(P<0.05).Compared with the control group,the diarrhea rate decreased significantly.At the same time,the digestive enzyme activity of jejunum of fattening pigs was significantly increased by adding different proportions of fructo-oligosaccharides,and the digestive enzyme activities of intestinal trypsin,lipase and amylase increased with the increase of adding proportion.however,the digestive enzyme activity of fattening pigs treated with 0.1%fruit oligosaccharides was not significantly different from that of the control group,and the intestinal digestive enzyme activity of fattening pigs treated with 1%fruit oligosaccharides was the highest.Therefore,adding different ratios of fructooligosaccharides significantly increased the digestibility of dry matter,crude fiber and crude fat in pigs.compared with the control group,the digestibility of dry matter,crude fiber and crude fat in pigs treated with 0.5%and 1%fruit oligosaccharides increased by 9%to 10%,20%to 26%and 14%to 19%,respectively,but had no significant effect on the digestibility of crude ash and crude protein.Adding 0.5%of fructo-oligosaccharides to the diet could significantly increase the activity of intestinal digestive enzymes and increase
