关于此课程： This course will explore the concepts driving current food production science (population growth, urbanization, emerging affluence, resource constraints, and underlying biological limits) with the main focus on livestock production. Each of the major food animal species (dairy, swine, beef, and poultry) will be covered in terms of their universal life cycles, constraints to production and emerging societal issues. Throughout the course, we will tackle some difficult and important questions: What are the major health benefits and potential concerns regarding the production and consumption of animal products? How does animal production affect the efficient use of resources and impact our environment? Can cost of production be reduced to meet growing demand for animal products around the globe while maintaining health and safety for both animals and consumers? What are the different types of animal food production systems? Myths and misconceptions surrounding the animal food systems will be discussed. We’ll also look closely at some of the global issues, problems, and challenges in these food systems which scientists, farmers, and veterinarians, are attempting to solve through collaboration. Lectures will be delivered by several experts from the University of Pennsylvania, School of Veterinary Medicine who are intimately involved in the study and advancement of animal production systems. The course is geared towards learners who seek a greater understanding of animal food systems as well as those who might have never visited an animal farm, but have a desire to learn more about where some of our food comes from and issues surrounding sustainability.
此课程适用人群： No prior knowledge of the many topics surrounding animal production farming is required to take this course. The content of this course is geared towards those who have an interest in food systems with or without experience in the subject.
