Although essentially a guide to breeds and types of domesticated pig, this book also takes a look at their wild ancestors and relatives in considerable detail, and will therefore be of interest to mammalogists and natural historians. Each species account, whether for wild, domesticated or feral, looks at the factors that have shaped the development of the breed, the movement of pigs in history, their place in certain cultures, and current pig industries. Breed entries are in geographical sections, and include reference to rare or now extinct breeds. Over 375 breeds are covered in total.
