ABSTRACT A feeding trial with 96 piglets was performed to investigate the effect of added soluble (SDF) and insoluble dietary fibre (IDF) sources on performance, apparent total tract digestibility (ATTD), concentration of microbial metabolites and pro-inflammatory marker genes as indicators for immune response. Piglets were allotted to four treatments (T): T1 control, T2 with soybean hulls (IDF/SDF: 8.35) and T3 and T4 with two different kinds of lignocellulose (IDF/SDF: >70). Diets were isofibrous for their value of total dietary fibre to underline the particular physicochemical properties of fibre sources. No differences were observed regarding average daily feed intake, average daily gain (ADG), feed conversion ratio and body weight, while T2 expressed higher ADG in the grower phase (day 14-54) vs. T3. Soybean hulls (T2) resulted in higher ATTD of dry matter and organic matter vs. T4; ether extract vs. T1 and neutral detergent fibre vs. T1, T2 and T3. The concentration of short chain fatty acids did not differ among treatments. Ileal digesta in T2 generated higher amounts of cadaverine vs. T3 and T4, likewise T1 vs. T4. Finally, no impact on immune response was detected. In conclusion, soybean hulls affected ATTD positively and lignocellulose prevented the formation of cadaverine, no overall direct response of SDF nor of IDF for the inclusion level were observed.

大豆皮和木质纤维素对仔猪生产性能、营养物质消化率、微生物代谢物和免疫反应的影响


摘要 对 96 头仔猪进行饲喂试验，以研究添加可溶性膳食纤维 (SDF) 和不溶性膳食纤维 (IDF) 来源对生产性能、表观总消化道消化率 (ATTD)、微生物代谢物浓度和促炎标记基因的影响为指标用于免疫反应。仔猪被分配到四种处理（T）：T1 对照、T2 大豆皮处理（IDF/SDF：8.35）以及 T3 和 T4 两种不同种类的木质纤维素处理（IDF/SDF：>70）。饮食中的总膳食纤维价值是等纤维的，以强调纤维来源的特定理化特性。在平均日采食量、平均日增重 (ADG)、饲料转化率和体重方面没有观察到差异，而 T2 在生长阶段（第 14-54 天）比 T3 表现出更高的 ADG。与 T4 相比，大豆皮 (T2) 导致干物质和有机质的 ATTD 更高；乙醚提取物与 T1 比较，中性洗涤纤维与 T1、T2 和 T3 比较。不同处理之间短链脂肪酸的浓度没有差异。 T2 中的回肠食糜产生的尸胺含量高于 T3 和 T4，同样，T1 高于 T4。最后，没有检测到对免疫反应的影响。总之，大豆皮对 ATTD 产生积极影响，木质纤维素阻止尸胺的形成，没有观察到 SDF 或 IDF 对包含水平的总体直接反应。
