Figure 3.

Bacterial groups and yeasts (log CFU/g) cultivated from colon digesta collected at 29, 30, 33, and 39 days of age from piglets fed after weaning (at 28 days) a starter diet (C) with 0.04% of essential oils mixture containing limonene, pinene, and eugenol. The piglets were reared either at an experimental (EF) of commercial farm (CF). The significant differences (P < .05) between days within one group are marked with different small letters (a, b), and the differences between groups on one day are marked with capital letters (A, B). For clarity, only columns that differ are marked.
