Which part of a corn plant will typically be consumed first by cattle?

1. Ear

2. Husk

3. Leaf

4. Stock

The correct answer is: Ear

The ear of the corn plant is typically the part that cattle will consume first. This is because the ear contains the kernels, which are high in energy and nutrients, making them particularly appealing to livestock. Cattle are attracted to the sweet, starchy kernels found on the ear, which provide an excellent source of carbohydrates and energy necessary for their growth and maintenance. The other parts, such as the husk, leaves, and stalk, are generally less desirable. While the husk and leaves do contain some nutritional value, they are more fibrous and offer lower energy content compared to the kernels. The stalk is primarily composed of cellulose and is often less palatable for cattle. Therefore, cattle will naturally gravitate towards the ear first in their feeding behavior due to its superior nutritional profile.
