Jersey is a breed of what type of animal?

The correct answer is that Jersey is a breed of dairy cattle. Jerseys are well-known for their rich milk production, which has a high butterfat content, making their milk particularly valuable for cheese and butter production. This breed originated from the island of Jersey in the English Channel and is favored in the dairy industry for its efficiency in converting feed into milk, as well as the high quality of its milk.

In contrast, the other options refer to different types of livestock. Poultry refers to birds such as chickens and ducks raised for their meat or eggs, while sheep are raised primarily for wool, meat, and milk. Swine, or pigs, are raised mainly for pork production. Therefore, while all the other choices represent important agricultural animals, only dairy cattle accurately describes the breed Jersey.
