In order to obtain the certificate, students will need to successfully complete ANSC 422, Companion Animal Nutrition, and two additional courses of their choosing from the list below.

  • Pet Food & Feed Manufacturing (ANSC 424; 3 credits); Section A 
  • Advanced Companion Animal Nutrition (ANSC 526; 3 credits); Section A
  • Pet Food Formulation, Regulations, and Market Trends (ANSC 499; 3 credits); Section MRG

As a current student at Illinois, you must register for section A in each of these courses. 

Companion Animal Nutrition (ANSC 422; 3 credits)

Required for certificate and pre-requisite for ANSC 526 - This course will cover the digestive physiology and basic nutritional considerations of companion animals, with primary focus on dogs and cats. Topics will include macronutrient and micronutrient digestion, metabolism, and function, nutritional idiosyncrasies of dogs and cats, unique nutritional needs throughout the life cycle, nutrient needs during exercise, common pet food ingredients, and nutritional sustainability.
