It's very important knowing which digestive tract your livestock has. This factor determines how your animal behaves and what it eats. Why cattle take so long to chew food. Why chickens need food that has added grit to it. Why swine can't digest large amounts of roughage. It all depends on their digestive systems! As an owner of livestock, this information should be known and should be followed. That way it's easier to see if your livestock is behaving differently than the other animals in the herd. It also lets you keep your animal healthy and properly digestive. Do you know which digestive tract your animal has? These are the possible choices: Non-ruminant (monogastric), ruminant, and poultry.
