Swine diseases are caused by bacterial and viral pathogens, nutritional and genetic factors. Some of the diseases caused by bacterial agents are bordetelosis, colitis, exudative epidermitis, listeriosis, swine dysentery, etc. Some viral swine diseases are African swine fever, blue eye disease, porcine respiratory coronavirus infection, swine vesicular disease, etc. Nutritional deficiencies in pigs may occur due to iron, vitamin E, calcium, vitamin D and biotin deficiencies, among others. A number of parasites such as Ascaris suum, Cryptosporidium, red stomach worm, Metastrongylus spp, etc. cause diseases in pigs. These diseases can lead to significant economic losses due to reduced productivity. The management of health issues in large swine population requires a major focus on biosecurity. Vaccination is the chief management tool to enhance immunity in swines. By using the combined strategy of minimizing disease challenge and augmenting individual and herd immunity by vaccinations, many swine diseases can be controlled. This book is a compilation of chapters that discuss the most vital concepts and emerging trends in the field of swine health and disease. It explores all the important aspects of swine health in the present day scenario. It is a collective contribution of a renowned group of international experts.
