Which breeds are listed for pork production?

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

Answer: (A)

In pork production, certain swine breeds are recognized for their specific roles in a production system. The classic group includes Yorkshire, Chester White, American Landrace as maternal breeds that contribute good litter size and mothering ability, and Hampshire and Duroc as terminal or growth/quality-focused breeds. Together, these five are the commonly cited set for pork production.

The other options comprise cattle breeds—beef types like Hereford, Angus, Charolais, Brahman—and dairy types like Holstein, Jersey, Brown Swiss—so they’re not associated with pork production. Duroc is a swine breed used in pork production, but on its own it isn’t the complete list of breeds typically listed for pork production.
