The BS in Animal Science at Michigan State University combines a strong foundation in biological and animal sciences with practical experience, preparing students for careers across animal production, agribusiness, research, veterinary medicine, and human-animal interaction. Students study animal anatomy and physiology, nutrition, genetics, management, animal health, and behavior, while choosing a concentration that matches their interests, including animal biology/preveterinary, animal industry, companion and exotic animal industry, dairy industry, or equine industry.
Curriculum Structure
Year 1: Students begin with the fundamentals of animal agriculture and biological science through courses such as ANS 110 Introductory Animal Agriculture, ANS 110L Introductory Animal Agriculture Laboratory, and BS 161 Cell and Molecular Biology, while ANS 101 Professional Development in Animal Science I introduces professional development.
Year 2: Students expand their understanding of animal-agriculture disciplines through ANS 210 Introduction to Disciplines in Animal Agriculture, alongside introductory management options such as ANS 134 Dairy Production I, ANS 222 Introductory Beef Cattle Management, or ANS 282 Companion Animal Biology and Management. The curriculum also begins developing analytical and scientific skills through statistics and organic chemistry requirements.
Year 3: Students move into more specialized scientific study with courses such as ANS 305 Applied Animal Behavior, ANS 307 Animal Reproduction, ANS 309 Animal Health and Disease Management, ANS 313 Principles of Animal Feeding and Nutrition, and ANS 314 Genetic Improvement of Domestic Animals. Students also complete ANS 301 Professional Development in Animal Science II, strengthening their preparation for professional careers.
Year 4: The final year allows students to deepen their chosen area through advanced subjects such as ANS 422 Advanced Beef Cattle Feedlot Management, ANS 434 Dairy Management II, ANS 442 Advanced Horse Management, or ANS 482 Advanced Companion Animal Management, depending on their pathway. Students also complete ANS 401 Ethical Issues in Animal Agriculture, integrating scientific knowledge with professional and ethical considerations.
