Which of the following animals is known for its high milk production?

Dairy cows are specifically bred and managed to optimize milk production, making them the clear choice for high dairy yield. They undergo selective breeding, which enhances their genetic traits related to milk quantity and quality. Dairy cows have specific physiological characteristics, like a larger udder capacity and a specialized metabolism that supports lactation.

In contrast, beef cattle are raised primarily for meat rather than milk, focusing on muscle development rather than lactation. Layer hens, while known for egg production, do not produce milk at all. Draft horses are bred for heavy pulling and work-related tasks instead of for milk production. This distinction among these animals highlights why dairy cows are recognized for their superior capability in milk production.
