    In svvnie: Boar (male), sow (female), barrow (castrated male), shote (growing animal), pig (female animal that has not been bred [gilt], and male of same age). The male animals are strongly built and have a highly de- veloped musculature, especially at the neck and shoulders. In the boar, the skin on the shoulder is cartilaginous in ap- pearance. The billy goat and the boar have a characteristic, unpleasant odor which also permeates the flesh. This odor remains with the animal even for a short time after castration. 2. AGE. The teeth are the best indicators of the age of an animal. The incisors are called nippers (pincers), situated one on each side of the median line, intermediates (laterals), external to the nippers, and corners, external to the intermediates. The intermediates in ruminants are called first and second laterals, as there are two located on each side. The milk teeth are smaller and have a whiter color than the permanent teeth.

At the age of twelve to fifteen years most of the teeth drop out. In cows the age may also be determined by the horns, as a ring is formed on the horn during each period of
