Choosing a college major is one of the first big steps toward graduating, but with so many options, it can feel overwhelming. Especially when majors like animal science and biology seem so similar. But don’t worry! We’re here to break down the similarities and differences so you can choose the right major for you.
Similarities
Both animal science and biology majors focus on the science of life. You’ll take courses in chemistry, biostatistics, and genetics. These majors allow for hands-on work in the lab and theoretical work in the classroom. You might even go out in the field to collect data for undergraduate research.
In either major, you’ll gain valuable skills in quantitative reasoning, writing, communication, and scientific literacy that employers and graduate schools are looking for. Both animal science and biology can also serve as strong foundations for veterinary, medical, or biological graduate studies.

Differences
While both majors focus on living organisms, they apply that focus differently.
Animal science works with livestock animals in particular, like cows, sheep, pigs, and chickens. They look at the nutrition, breeding, health, and production of these animals, applying research directly to the farm. This major takes more classes in animal handling, breeding, nutrition, and agriculture. And at BYU-Idaho, you’ll work with real animals at our Agriculture Science Center!
Biology, on the other hand, is broader and more theoretical. You could study any living organism, from something as small as a plant cell to something as large as a whale. Biology looks at the function, evolution, and molecular processes in living organisms. Biology majors spend significant time collecting research in labs and in the field. This major typically includes more coursework in chemistry, physics, and mathematics.
Careers
Although these majors share some overlap, they’ll lead you down different career paths. But no matter which you choose, both majors will lead you to rewarding work that makes a real impact on the world.
As an animal science major, you might get a job as a:
- Veterinarian
- Agricultural scientist
- Animal biotechnologist
- Livestock manager
- Animal nutritionist
- Zookeeper
As a biology major, you might get a job as a:
- Microbiologist
- Environmental scientist
- Forensic scientist
- Biologist
- Dentist
- Physician
What Will You Choose?
Deciding between the animal science and biology majors comes down to your interests and career goals. Both majors explore the science of life and prepare you with skills in research, communication, and analytics that employers and graduate schools want.
If you love hands-on, animal-focused science, then animal science may be the perfect fit for you. But if you’re drawn to a broader, research-based field full of discovery and possibility, consider majoring in biology. Whether you’re passionate about farm animals or microscopic organisms, both majors offer exciting opportunities to explore the living world and prepare for a meaningful career.
