A new report from the Centre for Feed Innovation analyzes the rising use of alternative ingredients in American pet diets. The findings examine how common components like yeast and seaweed are integrated into thousands of dog and cat food products across the United States.
Why it matters
Pet food manufacturers are increasingly adopting alternative proteins and oils to diversify their ingredient sourcing while attempting to reduce the environmental footprint of their products. This shift aims to lower land use and greenhouse gas emissions compared to traditional chicken-based protein sources.
The report evaluated 6,803 U.S. pet food products from KibbleLab to track ingredient trends. It identifies yeast protein and algal oil as top priorities for future development due to their potential for sustainability.
The players
Centre for Feed Innovation
An industry organization that researches and reports on advancements in animal nutrition and feed sustainability.
Pet Sustainability Coalition
A group that works with companies to improve the environmental and social performance of the pet industry.
The details
The analysis focuses on nine emerging ingredients, including black soldier fly larvae, cultivated meat, and various seaweed and algal sources. These alternatives are evaluated for their environmental efficiency, specifically their ability to require less land than conventional poultry and to reduce dependence on wild-capture fisheries for marine oils. Manufacturers use this data to refine product development and improve supply chain sustainability.
