Cud population to live and function. Consumption by ruminants of an insufficiently fibrous diet leads to little cud formation and therefore lowered amounts of saliva production. This in turn is associated with rumen acidosis, where the rumen pH can fall to 5 or lower. Rumen acidosis is associated with a lowered appetite which leads to still lower rates of saliva secretion. Eventually, a collapse of the microbial ecosystem in the rumen will occur because of the low pH. Acute rumen acidosis can lead to death of the animal, and will occur if the animal is allowed to eat a diet with
Chewing tobacco was unknown. At that time, it was commonly used by players and coaches alike. Smokeless tobacco use became rampant by players by the early 1900s. They liked chewing tobacco because it kept their mouths (and their mitts) moist on the dusty infield. The use of chewing tobacco in baseball steadily increased until the mid-20th century, when cigarettes became popular and took the place of some players' smokeless tobacco habit. Today, however, more baseball players are actually using dipping tobacco, not chewing tobacco. As shown below, a number of notable players have died of oral cancer as a result. Joe Garagiola,
