Day 9	21.0 ± 4.95	1.51E-07 ± 4.85E-08^a	1.02E-07 ± 1.76E-08^a
Day 21	26.0 ± 4.45	1.56E-07 ± 5.24E-08^a	1.07E-07 ± 2.81E-08^ab

Number, length and diameter of microvilli observed on IPEC-J2 on a surface of 5 μm were determined

* Numbers are an average (±SD) of three TEM observations, expressed in μm for the columns length and diameter. Numbers with the same letter are not significantly different (p < 0.05)
