Which dairy breeds are listed for milk production?

• A. Hereford, Angus, Charolais, Brahman
• B. Holstein, Jersey, Brown Swiss
• C. Yorkshire, Chester White, American Landrace, Hampshire, Duroc
• D. Duroc

Answer: (B)

The key idea is identifying which breeds are used for milk production. Holstein, Jersey, and Brown Swiss are classic dairy cattle breeds bred for milking performance. Holsteins lead in overall milk volume, Jerseys are renowned for high milk fat and protein content, and Brown Swiss are valued for sturdy milk production and good milk composition. The other options show beef breeds (Hereford, Angus, Charolais, Brahman) or pig breeds (Yorkshire, Chester White, American Landrace, Hampshire, Duroc), which are not raised for milk production. So the dairy breeds listed are Holstein, Jersey, and Brown Swiss.
