This book provides basic information on pig diseases on to which more specialist knowledge can be built. The emphasis is on the multiplicity of factors that are required for disease to appear in animal populations, with special importance being given to the role of management in the development of the disease in populations of pigs and to the part played by the environment in the initiation of disease in animals. The author uses plain, straightforward language, avoiding jargon and complex scientific terms. This third, revised and extended edition includes new sections on aberrant behavioural patterns; abscesses; blue-eared pig disease; colitis; examination of the male and female genital tracts; food consumption guide; fractures of bones; haematoma of the ear; hair balls; muscle damage; osteochondrosis dissecans (leg weakness); posterior repositioning of the urinary bladder; pressure ulcers; swollen testicles; and vulval oedema.
