Livestock plays a crucial role in the economies of many developing countries. They provide a source of food, particularly protein, and can generate income, employment opportunities, and foreign exchange. For low-income farmers, livestock can act as a means of transport, provide draught power, and serve as a store of wealth. In addition, livestock can provide organic fertilizer for crop production. While consumption of livestock and livestock products is still relatively low in developing countries, it is rapidly increasing. This book provides an analysis of the development of world trade in livestock and livestock products. It also covers important economic tools used in livestock, including theory and practical applications, with a focus on animal health economics. This book will be helpful to postgraduate students of economics/agricultural economics, research scholars, livestock economists, and other professionals working in the livestock and crop production systems.
