Holstein is a breed of what type of animal?

Holsteins are a breed of dairy cattle, renowned for their distinctive black and white coloring, which makes them easily recognizable. They are primarily raised for milk production and are one of the most common breeds of dairy cattle in the world. Holsteins have been selectively bred for high milk yields, and their productivity is informed by both genetics and management practices in dairy farming.

Their size and high milk production capabilities make them optimal for dairy operations, which focus on the efficiency and volume of milk output. Their lactation period and milk quality are also factors contributing to their popularity in the dairy industry. In contrast, the other options pertain to different types of livestock; beef cattle are bred for meat production, pigs for pork, and chickens for both meat and egg production, which distinguishes their roles and breeding objectives within agriculture.
