What is the first component of corn residue that cattle typically consume?

1. Husks

2. Leaves

3. Downed ears and grain

4. Stalk

The correct answer is: Downed ears and grain

The primary component of corn residue that cattle typically consume first is downed ears and grain. When cattle are given access to corn fields after harvest, they naturally gravitate towards the most nutrient-dense parts of the plant that remain, which includes the fallen ears of corn along with any grain that may have been detached during harvesting. These components are more palatable and provide higher energy content compared to other parts of the debris, making them the first choice for grazing cattle. This behavior highlights the grazing patterns of cattle, as they seek out the most valuable food sources in their environment. Downed ears and any grain left behind are rich in carbohydrates, which are essential for energy, especially in grazing scenarios where cattle need efficient nutrient intake to maintain their health and productivity. The other parts of corn residue, such as husks, leaves, and stalks, will be consumed later as cattle clear out the remaining material, but they lack the immediate appeal and nutritional value that downed ears and grain provide.
