The aim of this study was to compare the influence of different compositions of creep compound feed (CCF) (C-I - control group; TG-II - a CCF containing wheat bran extruded and fermented with ; TG-III - a creep compound feed containing sugar beet pulp) on the piglets' growth performance, blood parameters, fecal microbial profile and physicochemical characteristics. Moreover, the fecal volatile compound (VC) profile was analyzed as a possible chemical marker related to changes in the fecal microbial profile and physicochemical characteristics. A 21-day experiment was conducted using 1-day-old 300 Large White/Norwegian Landrace piglets. The highest body weight (at the 21st day) was found in piglets of the TG-III group, and both treated groups showed lower feed conversion ratios. At the end of the experiment, significantly higher counts in the feces of both treated groups were found, and a correlation between fecal textural hardness and the count was established ( = 0.475). Significant correlations of piglets' individual fecal VC with microbiological parameters and fecal pH were established [ with 3-n-nonadecanol-1; enterobacteria with butyric acid <2-methyl->; pentanoic acid, 4-methyl-; eicosene(E)-, etc.]. It can be concluded that local material could be successfully incorporated into CCF preparation without impairing animal metabolism.
本研究的目的是比较不同组成的教槽配合饲料(CCF)(C-I - 对照组;TG-II - 一种含有经挤压和发酵的麦麸的CCF;TG-III - 一种含有甜菜粕的教槽配合饲料)对仔猪生长性能、血液参数、粪便微生物谱和理化特性的影响。此外,分析了粪便挥发性化合物(VC)谱,作为与粪便微生物谱和理化特性变化相关的一种可能的化学标志物。使用1日龄的300头大白/挪威长白仔猪进行了为期21天的实验。TG-III组仔猪在第21天体重最高,且两个处理组的饲料转化率均较低。实验结束时,两个处理组粪便中的[具体菌名]计数均显著更高,并且建立了粪便质地硬度与[具体菌名]计数之间的相关性(= 0.475)。建立了仔猪个体粪便VC与微生物参数和粪便pH之间的显著相关性[与3-n-十九烷醇-1相关;肠杆菌与丁酸<2-甲基->相关;4-甲基戊酸;(E)-二十碳烯等]。可以得出结论,当地原料可以成功地纳入CCF制备中,而不会损害动物代谢。
