As a form of applied biology, animal science plays a crucial role in ensuring animal health and productivity. It utilises principles from various biological fields, such as genetics, nutrition, and immunology, to enhance the care and management of domesticated animals. This goes beyond just treating sick animals; it’s about using science to prevent disease and create optimal conditions that enhance both animal well-being and the production of products like meat, milk, and eggs.

Animal nutrition is a key component of applied biology. Scientists formulate balanced diets to ensure animals receive the proper nutrients for their specific life stage and purpose. For example, a diet for a lactating dairy cow will be different from one for a young growing horse (yearlings) or beef cattle in a finishing phase. Proper nutrition is critical for safe growth, reproduction, and overall health.

Formulation and diet balance, in the form of calculation and quantification of requirements, is often perceived as the foundation of animal nutrition.

Feed milling and production turn raw ingredients into safe, balanced feeds that support animal health and performance. By integrating biology, nutrition, and engineering with mathematics and biochemistry, modern mills enhance efficiency, minimise waste, and ensure consistent quality for sustainable food/feed systems.

Animal welfare and Ag sustainability ensure animals are cared for ethically while resources are managed responsibly. Together, they safeguard animal health, support productivity, and protect ecosystems—building trust in food systems and securing the future of the planet.

Feed biosecurity protects feed from contamination and disease, while food security ensures consistent access to safe, nutritious food. In animal science, both rely on reliable animal-derived products and efficient feed systems.
