Popis: Abstract Background Forages are widely used in horse diets. Different in vitro techniques are being tried to determine the fermentation levels of forages in the horse digestive tract. Objectives This study aimed to evaluate the digestion levels of four dry forages commonly used in horse nutrition: alfalfa herbage, meadow hay, wheat straw, and Italian ryegrass. In vitro total digestion (TDT), in vitro Sunvold–large intestine digestion (SDT) and in vitro Menke–large intestine digestion (MDT) techniques were compared. Methods The study determined in vitro true dry matter digestion (T‐DMD), in vitro true organic matter digestion (T‐OMD) and in vitro true neutral detergent fibre digestion (T‐NDFD). Additionally, concentrations of straight short‐chain fatty acids (SCFAs; acetic acid – AA, propionic acid , butyric acid, and valeric acid ) and branched short‐chain fatty acids (BSCFA) were assessed. Results The highest in vitro T‐DMD, T‐OMD and T‐NDFD values were determined by the in vitro TDT for the four forages (p
