The British Saddleback takes its name from the breed's most distinctive feature—the white saddle or belt marking encircling the body over the shoulders and front legs—combined with its British origin. The full name "British Saddleback" distinguishes this breed from other saddleback-patterned pigs that existed historically in various countries, though the British version is now the most prominent. The breed name is often shortened to simply "Saddleback" in British contexts where the national origin is understood, though "British Saddleback" remains the official designation in breed registries.
The modern British Saddleback was formed in 1967 through the amalgamation of two regional British breeds: the Essex and the Wessex Saddleback. Both parent breeds displayed the characteristic saddleback color pattern but had regional differences in type and performance. The Essex, from southeastern England, was known for excellent mothering and constitution, while the Wessex, from southwestern England, contributed growth and carcass quality. By merging these similar breeds into a unified British Saddleback, breed societies aimed to strengthen the gene pool and create a more versatile, productive saddleback pig while maintaining the iconic color pattern and outdoor hardiness.
Before the 1967 amalgamation, references to "Essex Saddleback" and "Wessex Saddleback" as distinct breeds appear in agricultural literature, and some older farmers may still use these regional names though they technically no longer exist as separate breeds. Historical writings sometimes mention other saddleback-patterned pigs including the "Hampshire" (an American breed with similar coloration but different conformation, not to be confused with the British Saddlebacks) and various local saddleback types that existed throughout Britain before standardization.
The scientific classification places British Saddlebacks within Sus scrofa domesticus alongside all domestic pigs. Within breed registries maintained by the British Saddleback Breeders Club in the UK and various registries in countries where the breed has been exported, animals must display the characteristic black coloration with white saddle marking, lop ears, and appropriate conformation to qualify for registration. The distinctive color pattern makes visual breed identification straightforward, though the width and exact placement of the white saddle varies somewhat among individuals.
