Animal Science Major & Minor

Make a meaningful impact through animal science

Spark discoveries and disseminate new knowledge about the biology and management of domestic animals and put our knowledge to work to make a positive impact in the world. Animal Science offers undergraduate and graduate programs on the biology and management of food, laboratory and companion animal species.

Our goals are to discover and develop new techniques and information to benefit animals, agriculture and human health. The department’s faculty members, many internationally recognized, have diverse interests in animal management, breeding, genetics, physiology, nutrition, growth biology and microbiology.

Major in Animal Science

Bachelor of Science (B.S.)

The Animal Science major prepares students for study in veterinary medicine or careers in animal production, biotechnology and conservation and has been nationally recognized for its work in animal breeding and genetics, nutrition, physiology, growth, behavior and management. Join students and professors who go beyond the classroom to explore ideas and tackle some of the complex challenges of our times. You’ll be prepared to find positions immediately upon graduation, or enter a graduate or professional school to obtain an advanced degree.

The animal sciences major offers an opportunity to apply animal biology, biochemistry, molecular biology and other life sciences to the study of animal breeding and genetics, nutrition, physiology, growth, behavior and management. The curriculum is flexible and can be applied to a great variety of species, from farm animals and pets to laboratory animals and even some exotics. Students are encouraged, with the help of a faculty advisor, to plan an individual curriculum that suits their interests and career goals.

CALS seeks students who maintain a rigorous high school curriculum and demonstrate an outstanding record of academic achievement. Admissions requirements include:

  • 4 Units of English

  • 4 Units of Mathematics (including pre-calculus, calculus recommended)

  • 3 Units of Science (biology, chemistry and physics recommended)

  • Also recommended: statistics

  • Agriculture courses are strongly encouraged

Concentrations

Students must select one of the following concentrations: Integrative Physiology & Nutrition; Pre-Veterinary Medicine; Dairy Management; Applied Animal Biology & Management; Animal Ecology & Conservation.  Concentrations are chosen second semester Sophomore year. Note: If you are a Pre-Vet, it does NOT mean that you have to take the Pre-Vet concentration. You can take any of the five concentrations, still apply to vet school, and keep your options open. However each vet school has its own admission requirements. You are responsible to ensure you take all required courses for the vet schools you wish to apply to.

ANSC 2210 – Principles of Animal Genetics

Examination of basic genetic principles and their application to the improvement of domestic animals, with emphasis on the effects of selection on animal populations and an introduction to the application of molecular techniques to animal improvement.

ANSC 3510 – Dairy Herd Management

Application of scientific principles to practical herd management with components of reproduction, milking, housing, records and production economics. Laboratories emphasize practical applications, analyses of alternatives, decision-making, field trips and discussion.

ANSC 3700 – Immunology in Animal Health and Disease 

Discuss concepts in immunology, with a focus on those that are important to domestic animal health and disease prevention. Immunological principles applied to understand current literature, research, and practices.

Students specializing in animal science have the opportunity, with the help of their advisors, to develop a curriculum that fulfills individual interests and allows a broad selection of courses. For example, a student interested in a production-oriented career might take courses in agronomy, farm management, agricultural engineering and economics to complement their animal science courses.

On the other hand, students with a more basic interest in animal biology might take organic chemistry, biochemistry, microbiology and other courses in the biological and physical sciences. While one student may be captivated by the molecular biology of the developing embryo, a classmate may be equally fascinated by the nutrition in the domestic cat or by the mathematics of genetic selection in the horse. No two students need to have identical programs.

Cornell’s Animal Science major also offers students the opportunity to:

  • Graduate with distinction in research
  • Receive top-notch training for careers in the dairy industry through the Dairy Fellows Program

All students are encouraged to take advantage of one or more opportunities for internships, a semester abroad, independent research or honors thesis research, as appropriate. For research or the Honor's Program in Research, consult with your advisor. Your advisor can help you identify possible internship opportunities and CALS has an office available to assist you. 

Resources:

Each student in the animal science major is assigned a faculty advisor. Your advisor plays several roles: guiding you through the requirements of the major and the College distribution requirements; helping you to clarify your educational and career goals; suggesting courses to help you meet your particular educational interests and career goals; and serving as a source of information about opportunities and services available to you through the College and University (e.g., study abroad, internships, career counseling, health and psychological services). If you make the effort to get to know your advisor, she or he also may serve as a reference for you for internships, jobs, or graduate school.

Minor in Animal Science

The Animal Science minor offers a great opportunity for any undergraduate student to pursue their interests in the Animal Science field in an accessible manor. Students declaring a minor in Animal Science must declare the minor prior to graduating.

The minor is satisfied by completing at least 15 credit hours of Animal Science courses. Students completing the Animal Science minor assemble courses, or demonstrate having the equivalent from elsewhere, that include basic and applied biology of animals (i.e. anatomy, physiology, nutrition, genetics) along with a selection of intermediate or advanced offerings from the Animal Science curriculum. 

Please consult with the Undergraduate Program Coordinator, lig27 [at] cornell.edu (Lindsay Glasner), if you are interested.
