Moreover, the faecal volatile compound (VC) profile was analysed as a possible chemical marker related to changes in the faecal microbial profile and physi-cochemical characteristics. A 21-day experiment was conducted using 1-day-old 300 Large White/Norwegian Landrace piglets. At the end of the experiment, significantly higher lactobacillus counts in the faeces of both treated groups were found, and a correlation between faecal textural hardness and the lacto-bacillus count was established (r = 0.475). Significant correlations of piglets’ individual faecal VC with mi-crobiological parameters and faecal pH were established (lactobacilli with 3-n-nonadecanol-1; enterobacteria with butyric acid<2-methyl->; pentanoic acid, 4-methyl-; eicosene(E)-, etc.). 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. It can be concluded that local material could be successfully incorporated into CCF preparation without impairing animal metabolism.
