Breed females when they are “in heat.”

10.8.3 Breed females when they are “in heat.”

Females must be bred when they are “in heat.” Signs of heat vary in different animals. See Table, page 135. Some animals should be bred only once during their heat (e.g. cattle, buffalo, sheep and goats), whereas other animals should be bred more than once during their heat (e.g. horses and pigs). See Table, page 135. Do not try to force animals to mate. The female may injure the male if she is not in heat.
