摘要
The effect of oligofructose (FOS) or trans-galactooligosaccharides (TOS) inclusion at 10 g/kg diet for growing pigs, at the expense of cornstarch (CON), on growth performance, nutrient digestibilities, and faecal physicochemical parameters was determined. In addition, concentration of volatile fatty acids (VFA) and bacterial α-glucosidase, β-glucosidase, β-galactosidase and β-glucuronidase activities in faeces were determined as markers of intestinal microflora metabolic activity. Twelve 35-day-old castrated pigs were allocated to CON, FOS and TOS dietary treatments for an experimental period of 4 weeks. Dietary treatments did not affect animal growth performance. FOS and TOS pigs tended to have a lower faecal output than CON pigs by approximately 6.0% and 1.7% respectively. FOS and TOS did not affect total tract apparent digestibility of dry matter, organic matter, fat, crude protein, crude fiber, ADF and cellulose. Digestibility of carbohydrate components such as nitrogen free extract and NDF was significantly (P ≤ 0.05) higher in TOS pigs compared to CON and FOS. Digestibility of hemicellulose in TOS pigs did not differ from FOS but was significantly higher from CON. The experimental period had a significant effect on most of the parameters determined. There were no significant (P ≤ 0.05) differences between treatments regarding total VFA concentration and faecal bacterial enzyme activities. Nevertheless, an increased saccharolytic activity in the gut of FOS and TOS pigs could be postulated by the trends for apparently higher VFA concentration and bacterial α-glucosidase and β-galactosidase activities.

测定了低聚果糖（FOS）或反式低聚半乳糖（TOS）以10g / kg饲料包含在生长猪中，以玉米淀粉（CON）为代价，对生长性能，营养物质消化率和粪便物理化学参数的影响。此外，粪便中挥发性脂肪酸（VFA）和细菌α-葡萄糖苷酶，β-葡萄糖苷酶，β-半乳糖苷酶和β-葡糖醛酸糖苷酶活性的浓度被确定为肠道微生物群落代谢活性的标志物。将12只35日龄阉割的猪分配至CON，FOS和TOS饮食处理，实验期为4周。膳食处理不影响动物的生长表现。 FOS和TOS猪的粪便产量往往比CON猪低约6.0％和1.7％。 FOS和TOS不影响干物质，有机物，脂肪，粗蛋白，粗纤维，ADF和纤维素的总管道表观消化率。与CON和FOS相比，TOS猪中碳水化合物组分（如无氮提取物和NDF）的消化率显着（P≤0.05）更高。 TOS猪中半纤维素的消化率与FOS无差异，但与CON显着较高。实验期对确定的大多数参数有显着影响。处理之间在总VFA浓度和粪便细菌酶活性方面没有显着（P≤0.05）差异。尽管如此，FOS和TOS猪肠道中的糖分解活性增加可以通过明显更高的VFA浓度和细菌α-葡萄糖苷酶和β-半乳糖苷酶活性的趋势来假定。
