The stomach of the sambar deer (Cervus unicolor unicolor)

In New Zealand, the sambar deer is reported to feed on a variety of grasses and browse material. In the specimens studied, the average volume of the sambar rumen was about 151. Thick, non-papillated pillars divided the rumen into a saccus dorsalis and a saccus ventralis. The lining of the rumen was covered with papillae; those in the roof area were short and poorly developed. The omasum was a well-developed organ with 47-71 (mean 57) laminae. These were covered with short and poorly developed papillae. It is concluded that these sambar deer stomachs were typical of a grass-roughage feeder. This contrasts with the previous classification of the sambar deer as an intermediate feeder.
