On average, Jersey milk contains a significantly higher butterfat percentage, typically ranging from 4.5% to 5.5%. This elevated fat content is why Jersey milk is renowned for its rich flavor and creamy texture, distinguishing it from milk produced by other common dairy breeds.

While standard milk contains a mix of A1 and A2 beta-casein proteins, a 2019 study at the University of Minnesota found that over 50% of its Holstein herd were A2/A2, a trait not actively selected for. In the USA, A2 milk comes from specific breeds and genetically tested herds, not just any cow.
