Devon: A breed of fine-boned dual-purpose cattle. North and South Devons are dark red, and belong to a type of red cattle bred for centuries in England. They thrive on pasture which would not be sufficient for larger breeds, and provide both meat and milk. (NOTE: They are commonly known as Red Rubies.) Farmers raising Devon cattle should focus on proper grazing management, health monitoring, and breeding practices to maintain herd productivity. Marketing the unique characteristics of Devon cattle, such as their hardiness and dual-purpose nature, can attract buyers and enhance farm profitability.
