Taste bud quantitation may provide useful parameters for interspecies comparisons of the gustatory system. The present study is a morphometric analysis of bovine taste papillae. Circumvallate and fungiform papillae from six bovine tongues were serially sectioned and, following staining, analyzed. Circumvallate papillae were found to have a mean volume of 3.66 +/- 2.82 mm3, a mean number of taste buds per papilla of 445 +/- 279, and a mean taste bud density of 155 +/- 112 buds/mm3. Values for lateral fungiform papillae for the same three parameters were 0.384 +/- 0.184 mm3, 13.2 +/- 13.4, and 40.8 +/- 46.6 buds/mm3, respectively. Values for dorsal fungiform papillae were 0.438 +/- 0.246 mm3, 4.39 +/- 4.78, and 14.0 +/- 17.1 buds/mm3, respectively. Circumvallate papillae were found to have a significantly greater volume, number of taste buds per papilla, and taste bud density than either type of fungiform papilla. These data should serve as background for biochemical, endocrinological, or neurological studies involving the bovine tongue.
味蕾定量分析可为味觉系统的种间比较提供有用参数。本研究是对牛味蕾乳头的形态计量学分析。对取自六条牛舌的轮廓乳头和菌状乳头进行连续切片，并在染色后进行分析。结果发现，轮廓乳头的平均体积为3.66±2.82立方毫米，每个乳头的味蕾平均数为445±279个，味蕾平均密度为155±112个/立方毫米。同一三个参数的外侧菌状乳头的值分别为0.384±0.184立方毫米、13.2±13.4个和40.8±46.6个/立方毫米。背侧菌状乳头的值分别为0.438±0.246立方毫米、4.39±4.78个和14.0±17.1个/立方毫米。结果发现，轮廓乳头的体积、每个乳头的味蕾数量和味蕾密度均显著大于任何一种菌状乳头。这些数据应为涉及牛舌的生化、内分泌或神经学研究提供背景资料。
