Animal Science Digest

This textbook is intended as a comprehensive introduction to the biology, care, and production of domestic animals and freshwater sh raised to provide food, as well as pets kept for companionship and recreation. The authors teaching and research experiences in agriculture, animal and dairy sciences, and veterinary medicine provide the professional expertise that underpins the clearly written discussions of advances in animal sciences affecting humans globally. Coverage includes breeds and life cycles of livestock and poultry; nutritional contributions of animal products to humans; the principles of animal genetics, anatomy, and physiology including reproduction, lactation and growth; animal disease and public health; and insects and their biological control. Each chapter stands on its own. Instructors can assign higher priority to certain chapters and arrange topics for study in keeping with their preferred course outlines. The text has been classroom-tested for four decades in more than 100 colleges and universities at home and abroad. Additionally, it is pedagogically enhanced with glossary terms in boldface type, study questions at the end of each chapter, more than 350 illustrations, and historical and philosophical quotations. These useful features aid students in comprehending scientic concepts as well as enjoying the pleasures derived from learning more about food-producing animals, horses, and popular pets.

Pond is for the mainstream introduction to animal science taught in every university that has a school of agriculture or animal science department. The result of years of teaching, the book provides students with a comprehensive and balanced overview of animal agriculture in contemporary society, taking into account the needs of students with highly varied cultural backgrounds and educational objectives.

By 2050 the world's population is projected to grow by one-third, reaching between 9 and 10 billion. With globalization and expected growth in global affluence, a substantial increase in per capita meat, dairy, and fish consumption is also anticipated. The demand for calories from animal products will nearly double, highlighting the critical importance of the world's animal agriculture system. Meeting the nutritional needs of this population and its demand for animal products will require a significant investment of resources as well as policy changes that are supportive of agricultural production. Ensuring sustainable agricultural growth will be essential to addressing this global challenge to food security. Critical Role of Animal Science Research in Food Security and Sustainability identifies areas of research and development, technology, and resource needs for research in the field of animal agriculture, both nationally and internationally. This report assesses the global demand for products of animal origin in 2050 within the framework of ensuring global food security; evaluates how climate change and natural resource constraints may impact the ability to meet future global demand for animal products in sustainable production systems; and identifies factors that may impact the ability of the United States to meet demand for animal products, including the need for trained human capital, product safety and quality, and effective communication and adoption of new knowledge, information, and technologies. The agricultural sector worldwide faces numerous daunting challenges that will require innovations, new technologies, and new ways of approaching agriculture if the food, feed, and fiber needs of the global population are to be met. The recommendations of Critical Role of Animal Science Research in Food Security and Sustainability will inform a new roadmap for animal science research to meet the challenges of sustainable animal production in the 21st century.

Introduction to Animal Science is one in a series of Just The Facts (JTF) textbooks created by the National Agricultural Institute for secondary and postsecondary programs in agriculture, food and natural resources (AFNR). This is a bold, new approach to textbooks. The textbook presents the essential knowledge of introductory animal science in outline format. This essential knowledge is supported by a major concept, learning objectives and key terms at the beginning of each section references and a short assessment at the end of each section. The content is further enhanced by connecting with a complementary PowerPoint and websites through QR codes (scanned by smartphones or tablets) or URLs. Based on the feedback from the first edition, the 2nd ed. has been revised. Minor errors and broken links were corrected as well as the addition of more illustrations to create a more effective teaching tool. To purchase electronic copies, inquire at: [email protected]
