Whenever it is possible, the medicine to be administered should be
mingled with a portion of food, and the animal thus cheated or coaxed
into taking it; since many instances are on record, in which the pig has
ruptured some vessel in his struggles, and died on the spot, or so
injured himself as to bring on inflammation and subsequent death.
Where this cannot be done, the following is the best method: Let a man
get the head of the animal firmly between his knees--without, however,
pinching it--while another secures the hinder parts. Then let the first
take hold of the head from below, raise it a little, and incline it
slightly toward the right, at the same time separating the lips on the
left side so as to form a hole into which the fluid may be gradually
poured--no more being introduced into the mouth at a time than can be
swallowed at once. Should the animal snort or choke, the head must be
released for a few moments, or he will be in danger of being strangled.
