Question

Why do we feed cows corn instead of grass, which is what they have evolved to eat (they are a class of mammals called ruminants)?

Answer 1

Cows are ruminants that have evolved to eat grass, but they are often fed corn instead. This is because corn provides a higher energy content and allows cows to grow more quickly. Corn is also cheaper and easier to produce, making it a convenient feed option for farmers.

Step-by-step explanation:

Cows are ruminants, which means they have evolved to eat large amounts of roughage or fiber like grass. However, in modern agriculture, cows are often fed corn instead. The main reason for this is that corn provides a higher energy content compared to grass, which allows cows to grow and put on weight more quickly. Corn is also cheaper and easier to produce in large quantities, making it a convenient feed option for farmers.
