Pedigree breeding is a breeding method focused primarily on the parentage of animals. To increase the level of certainty, as much information as possible is collected on several generations of ancestors. The pedigree breeding method does not focus on direct mating partners, but rather on bloodline combinations.
Monogastric or Non-ruminant animals do not possess a rumen, reticulum, omasum, or abomasum. Instead, once their food is ingested it will eventually go through a functional caecum. Donkeys and horses are monogastric.
