Short summary
The endangered Angler Saddleback pig is a fatty breed and has been fed high-fiber diets for decades. In view of this, a fatty acid composition different from that of commercial breeds was identified. In addition, the fatty acid composition in intramuscular fat and back fat was less correlated, suggesting a genetic effect in addition to dietary factors. Significant loci identified in genome-wide association studies underline the potential importance of this breed.
