Livestock that primarily depend on 20 percent protein hay are?

• A. Dairy cattle
• B. Beef cattle
• C. Pigs
• D. Chickens

Answer: (A)

Dairy cattle are the livestock that primarily depend on high-quality forage, such as hay with around 20 percent protein, to meet their nutritional needs. Dairy cattle require significant amounts of protein for milk production, growth, and overall health. High-protein hay provides the essential amino acids necessary for the lactation process, helping to optimize milk yield and quality.

While other livestock, such as beef cattle, pigs, and chickens, have different nutritional requirements and may consume various feeds, dairy cattle are specifically dependent on high-protein forage. Beef cattle and pigs generally require different protein sources and levels that may include grains or other feed types, while chickens, although they need protein, also have specific nutritional requirements that are typically met through a combination of grains, protein meals, and other supplements rather than relying heavily on high-protein hay alone.
