摘要
The aim of the present study was to investigate the precaecal and faecal digestibility of inulin (DP 10–12) and inulin/Enterococcus faecium mix, and the effects of these substances on nutrient digestibility and microbial gut flora. For the experiment four of eight male pigs were fitted with an end-to-end ileo-rectal anastomosis (IRA) with preserved ileo-caeco-colic valve. The residual pigs were used as intact partner (IN). The animals received 1.5 kg/day of a diet based on corn, wheat, barley and soybean meal, supplemented with either 8 × 109 CFU E. faecium/kg, 2% inulin or a mixture of both substances. The digestibility trial was carried out from weeks 4 to 8 after surgery. Precaecal digestibility of inulin was assessed to be 57%. The addition of E. faecium to the diet resulted in a similar precaecal digestibility of inulin of 55%. Supplementation of E. faecium, inulin, and a mixture of E. faecium and inulin did not affect precaecal and faecal nutrient digestibility with the exception of the precaecal digestibility of CF which increased when inulin alone was supplemented. Bacterial population in the digesta of IRA and IN pigs were not affected by the experimental diets except the concentration of bifidobacteria and lactobacilli. The supplementation of E. faecium to the diet significantly decreased the concentration of bifidobacteria and the population of lactobacilli inclined to decrease when IN pigs received the probiotic diet. The combination of E. faecium and inulin prevented a reduction of enterococci in faeces of IN pigs. The daily digesta excretion (DM) tended to decrease in IRA and IN pigs when inulin was supplemented. The results indicate that inulin (DP 10–12) in pig nutrition did partly react as a prebiotic as has been confirmed for humans. A combination of E. faecium and inulin improves the survival of the probiotic strain through the upper intestinal tract and allocates the synbiotic effect. Furthermore inulin might be able to show positive effects on precaecal and faecal microbial characteristics.

本研究的目的是调查菊粉的precaecal和粪便消化率(DP 10-12)和菊粉/肠球菌组合,和营养物质消化率和微生物肠道菌群这些物质的影响。在实验4的8雄性猪分别装有一个端到端回肠 - 直肠吻合术(IRA)与保留回肠caeco-绞痛阀。残余猪用作完整伙伴(IN)。动物接受1.5公斤/基于玉米,小麦,大麦和大豆粉饮食的一天,补充有任一8×10 SUP 9 / SUP CFU屎肠球菌/公斤,2%菊粉或二者的混合物物质。消化率试验进行了数周4-8手术后。菊糖Precaecal消化率被评估为57%。加E的肠球菌的饮食导致55%菊粉的一个类似precaecal消化率。屎肠球菌,菊糖,和E的混合物的补充屎肠球菌和菊粉没有影响precaecal和粪便养分消化率除CF的precaecal消化率仅菊粉进行了补充,当这增加的。细菌群体中的IRA的食糜和IN猪不受实验饮食除双歧杆菌和乳杆菌的浓度。 E的补充肠球菌的饮食显著下降双歧杆菌的浓度和乳杆菌的倾斜,以减少当猪接受益生菌饮食的人口。 E的组合屎肠球菌和菊粉防止减少肠球菌的猪粪便。每天消化排泄(DM)倾向于在IRA和猪,以减少时菊粉进行了补充。结果表明,菊粉(DP 10-12)在猪的营养为已证实对人类也部分地发生反应作为益生元。 E.的组合肠球菌和菊粉改善通过上肠道益生菌菌株的存活,并分配了合生元效果。此外菊粉也许能显示在precaecal和粪便微生物特性的积极影响。
