The effect of BHBA addition to the solid diet on the morphology of the rumen epithelium in young goats. Representative rumen epithelial micrograph in the groups of (A) CON, (B) LOW, (C) MIDDLE and (D) HIGH. Images were obtained through a light micrograph of rumen tissue (40× magnification). CON = starter supplemented with BHBA at 0 g/day per goat; LOW = starter supplemented with BHBA at 3 g/day per goat; MIDDLE = starter supplemented with BHBA at 6 g/day per goat; HIGH = starter supplemented with BHBA at 9 g/day per goat. BHBA = β-hydroxybutyric acid.
