In this lesson students will learn about the five types of nutrients and their purposes. This lesson will also cover symptoms of nutritional deficiencies in livestock. I divide this lesson into two class periods. On the first day we talk about nutrients and the second day we talk about the importance of nutrients for body functions such as growth, reproduction, and maintenance. At the end, students will have to pass a quiz that covers most of the main information taught during these lessons as a means to exhibit proficient comprehension of the information and its importance.
