Dairy breeds are specific types of cattle raised primarily for milk production. The most common dairy breeds include Holstein, Jersey, and Guernsey. Each breed has unique characteristics, such as milk yield, fat content, and adaptability to different environments. Holsteins are known for their high milk production, while Jerseys produce milk with a higher butterfat content, making it ideal for cheese and butter. Guernseys are valued for their rich, golden milk and efficient feed conversion. Understanding these breeds helps farmers select the right cattle for their dairy operations.
