Gastritis in the Short-Beaked Echidna (Tachyglossus aculeatus): Parallels with Ruminal Acidosis in Herbivores and Implications for the Understanding of Echidna Digestive Physiology

Short-beaked echidnas (Tachyglossus aculeatus) are endemic to Australia and south-eastern New Guinea (Indonesia and Papua New Guinea). In mainland Australia they feed primarily on termites. Echidnas have a single chambered stomach which is entirely lined with squamous (non-glandular) cells, and is histologically analogous to the rumen. The short-beaked echidna stomach has historically been understood to function as a grinding or...

Similarity of rumen degradable protein (RDP) degradation rates comparing in vitro and in situ techniques

Protein provided to ruminants can be divided into rumen degradable protein (RDP) and rumen undegradable protein (RUP). The RDP provides amino acids and ammonia-nitrogen which are vital to the growth of rumen microbes. An imbalance of the RDP supply and microbial RDP requirement can alter ruminal fermentation. The imbalance could lead to reproductive inefficiencies, inadequate growth, and ruminal acidosis. To...
