ANSC Feeds Practice Exam

Which of the following is an example of a carbonaceous concentrate?

1. Bermudagrass hay

2. Red clover hay

3. Animal tallow

4. Alfalfa hay

The correct answer is: Animal tallow

Animal tallow is a prime example of a carbonaceous concentrate due to its high energy content derived primarily from fats. Carbonaceous concentrates are feedstuffs typically high in carbohydrates and fats, providing readily available energy for livestock. Animal tallow, being a rendered fat, is concentrated in energy and low in fiber, making it an effective energy source for various types of livestock. In contrast, Bermudagrass hay, Red clover hay, and Alfalfa hay are forages that are higher in fiber and lower in energy compared to carbonaceous concentrates. These forages are considered proteinaceous or fibrous feeds, which are essential for ruminant digestion but do not predominantly serve as high-energy sources like animal tallow. Thus, selecting animal tallow aptly highlights the key characteristics of carbonaceous concentrates, which prioritize energy-rich components over fiber.
