Age from the teeth. — The ages of cattle may be determined with 

 a fair degree of accuracy by an examination of the teeth. There are 

 eight incisors in the lower jaw of mature cattle. There are no incisors 

 in the upper jaw, but a tough, fibrous pad instead, amply suited to the 

 grazing habits of cattle. The dentition at various ages is as follows: 



Age Incisors
