Animals get their nutrition either directly from plants they eat or indirectly by consuming other animals that have consumed plants. Some of the mechanisms through which nutrition can be obtained are suction feeding, fluid feeding, filter feeding, bulk feeding and deposit feeding. Good animal feeding is essential to ensure the welfare and health of animals, as well as the production of high quality and safe animal-derived products. Appropriate animal feeding and nutrition is also essential for the proper development and reproduction of animals. Furthermore, appropriate feeding helps the animals in developing strong immunity to fight infections. It also encourages better health in animals, which leads to increased productivity of products such as eggs, milk and meat. This book contains some path-breaking studies on the role of nutrition and feeding in improving animal production. It includes contributions of experts and scientists, which will provide innovative insights into this field. The book is a complete source of knowledge on the present status of this important area of study.
