Final answer:
Ruminant animals, such as cows and goats, have a complex four-stomached digestive system to break down cellulose and chew cud. Examples include deer and camels. Non-ruminant farm animals, such as horses and rabbits, have simpler digestive systems and do not chew cud; these include pigs and chickens.
Step-by-step explanation:
Ruminant and Non-Ruminant Farm Animals
Ruminants are herbivorous mammals that are able to break down cellulose in plant matter. They have a unique digestive system with four stomachs: the rumen, reticulum, omasum, and abomasum. This system allows them to regurgitate and re-chew their food, a process known as 'chewing the cud.' Non-ruminants, on the other hand, have a simpler digestive system and do not chew cud.

While ruminants play a crucial role in nomadic pastoral societies, providing meat, leather, wool, and other products, non-ruminants can also be important in commercial wildlife farming, contributing to the food, skin, fur, and pet trade industries.
