According to my findings below, cows have between 25,000 and 35,000 taste buds.
The Encyclopedia of Nursing and Allied Health, by R.D. Linda Richards
states that cows have 25,000 taste buds.
"According to Yale University researchers, some people are genetically
programmed to have more taste buds and, as a result, taste more
flavors in a particular food. (The number of taste buds varies in
different animal species. For example cows have 25,000 taste buds,
rabbits 17,000, and adult people approximately 10,000.) In general, a
person's ability to taste can lie anywhere in a spectrum from poor to
exceptional, with the ability to sense tastes increasing in proportion
to the number of taste buds present. The difference in the number of
taste buds can be extreme. Researchers have found anywhere from 11 to
1,100 taste buds per square inch in various young people tested. They
have also found that women tend to have more taste buds than men."

Distribution of taste buds on fungiform and circumvallate papillae of
The distribution of taste buds on the fungiform and circumvallate
papillae of the cow tongue has been determined. The two tongues
studied were from Holstein-Friesian cows four to six years of age;
they contained 14,765 and 21,691 taste buds, respectively. The tip of
the tongue is well supplied with fungiform papillae, and the posterior
portion contains the circumvallate papillae. The midportion of the
tongue contains relatively few taste papillae. The fungiform papillae
contained 1,580 and 1,838 taste buds on the two tongues, respectively,
and the circumvallate papillae were estimated to contain 13,185 and
19,853 taste buds."
