Final answer:
The Jersey breed produces milk with the highest percentage of butterfat of all dairy breeds, making it desirable for high butterfat products like premium ice cream and artisan cheeses.
Step-by-step explanation:
The dairy breed that produces milk with the highest percentage of butterfat of all dairy breeds is C) Jersey.
Jerseys are well-known for producing milk that is richer in butterfat compared to other breeds. While Holsteins are known for producing larger quantities of milk, the Jersey breed leads in terms of the concentration of butterfat. This characteristic makes Jersey milk highly desirable for producing products requiring high butterfat content, such as premium ice cream and artisan cheeses.
In regions with a strong dairy tradition, such as Wisconsin, the demand for products like cheese and butter is particularly high due to cultural preferences, which could further influence the choice of dairy breed based on the butterfat content of their milk.
