Cows have one large stomach, but it has four separate parts. Animals
with four parts in their stomach are called ruminants. Other ruminants
are giraffes, deer, sheep and goats. Ruminants eat fast and store
large amounts of grass or foliage in their stomachs.
The first part, called the rumen, stores and softens food. This is where
‘cud’ comes from. Cud is food that cows swallow, partly digest, bring
up and chew again. Cows may chew their cud for up to eight hours
a day.
Cows sometimes accidentally swallow bits of fences and metal. The
second, and smallest, part of the stomach collects these materials.
This prevents the cow from getting hurt. It is called the reticulum.

The third part acts like a filter. It takes in water and gets the nutrients
from food. It is called the omasum. Cows drink about a bathtub full of
water each day.
The fourth part is like a human stomach. This is where the final stage
of digestion occurs. It is called the abomasum.
The stomach of a cow is so large that it can be one-third of the weight
of an adult cow.
