Histomorphometric Characterization of Forestomach of Yak (Bos grunniens) in the Qinghai-Tibetan Plateau

Six forestomachs of yaks (Bos grunniens) were studied with gross dissection and histological methods. It was found that the forestomach of yak consisted of the following three parts, rumen, reticulum and omasum, which were composed of the mucosa, submucosa, muscularis and serosa. In addition, the mu...
