Which of the following is a pseudo-ruminant?<br><br> cow<br> pig<br> crow<br> horse
maria [59]

Answer:

The horse is a pseudo-ruminant.

Explanation:

Pseudo ruminants (for example, horses and rabbits), have a stomach similar to that of other animals that have a simple stomach. However, they have an extensive area called cecum that gives them an intermediate characteristic between ruminants and non-ruminants.

Horses are pseudo ruminants, so they only have one cavity in their stomach, unlike cows or sheep that have four cavities. They can digest the cellulose of the herb because they have a very developed blind, through which food passes before reaching the large intestine.
