Which dairy breed is known for producing golden-yellow milk?

The Guernsey breed is recognized for producing milk that has a distinctive golden-yellow coloration. This is primarily due to the breed's high levels of beta-carotene, which is a precursor to vitamin A and contributes to the rich yellow hue observed in their milk. The Guernsey breed has been notably bred for this characteristic, resulting in milk that is not only visually distinctive but also nutritious, being higher in certain vitamins compared to milk from other breeds.

The other breeds listed, while each having unique attributes and advantages in their milk production, do not typically exhibit the same golden-yellow coloration. For instance, the Jersey breed is also known for high butterfat content, but its milk is usually creamier rather than golden-colored. Holsteins are famed for their high volume of milk production but produce milk that is typically white to off-white in color. Ayrshires are recognized for the quality of their milk with moderate butterfat and protein levels but do not feature the same golden-yellow characteristics as Guernseys. Thus, the identification of the Guernsey breed with this specific trait is well justified.
