Effects of dietary additives on the histo-morphological changes in the jejunal (left-hand side panels) and colon (right-hand side panels) tissues in piglets 21 days after weaning. (Panels A–E) in the left hand side column illustrate the corresponding histomorphometry of jejunum tissue from NC, PC, FRM, FRMA and FRMAS groups whereas the left hand side panels, namely (panels F–J), are an histomorphometry of colon tissue from the NC, PC, FRM, FRMA and FRMAS, respectively. NC, PC, FRM, FRMA and FRMAS are defined as footnote (See legends for Table 1). Histo-micrographs were taken at 10× magnification.
