Observations on the macroscopic digestive anatomy of the Himalayan tahr (Hemitragus jemlahicus).
We measured macroscopic anatomical parameters of the digestive tract of 12 female Himalayan tahrs. According to morphological criteria used sensu Hofmann for the classification of ruminants into feeding types - in particular the reticuloruminal capacity measured as wet content weights, the ruminal pillar thickness, the reticular honeycomb structure, the size of the omasum and the size of the parotid glands - tahrs can be classified as predominantly grazing ruminants. As reported in other ruminant species, the length of the large intestine was a more constant parameter over a range of body weights than that of the small intestine. The weight of the parotid glands scaled to metabolic body weight.
