As M. tempus is an omnivore due to their monogastric digestive system, and is similar to a pigs digestive system, but with adaptations similar to that of bilbies (Thylacomyidae) due to the occasional low availability of prey and living food sources, resulting in adapted hindgut fermentation and a long digestive tract, (Tyndale-Biscoe C H 2005). Although M. tempus must ferment the consumed plant material, their gastrointestinal tracts are still incredibly different to those of foregut fermenters, such as cows. As mentioned earlier, the pig and bandicoot like teeth ensures M. tempus can easily rip apart their prey with their canines and incisors, while also able to masticate and grind up plant material with their molars (Mississippi State University, n.d). After mechanical digestion (with added chemical digestion from saliva and enzymes such as Amylase that breaks down starch (Rowan J P, Durrance K L, Combs G E, Fisher L Z 1997), the food is swallowed down the oesophagus by peristalsis (Cheeke P R, Dierenfeld E S 2010) and immediately into the gastric stomach, which is why they’re monogastric animals. In the stomach, the food is both mechanically digested by the churning of the stomach walls, and chemically digested by the high acidity from the hydrochloric acid, and enzymes secreted from goblet cells which break down the food into smaller particles (Rowan J P, et al 1997), this includes the beginning digestion of protein by the enzyme pepsin (Vet Sci 2010). However, this…
