The goal of our project was to reimagine the value of soybean meal (SBM) in pet foods by utilizing scientifically generated data to highlight its potential as a prebiotic. This shift aims to transform the negative perceptions surrounding SBM, largely due to concerns about anti-nutritional factors (ANFs) and indigestible oligosaccharides (OS), into a positive narrative that emphasizes its benefits for animal nutrition. Currently, only 0.5% of global soy production is used in pet food, largely because of the reputation that SBMs can hinder digestion and cause gastrointestinal issues in companion animals. However, our research demonstrated that the oligosaccharides found in soy can produce beneficial short-chain fatty acids, which may support gut health in companion animals. Throughout the project, we focused on characterizing SBMs through comprehensive analysis of their chemical composition, including key components such as crude protein, ether extract (fat), gross energy, and dietary fibers. This data enhanced our understanding of the nutritional profiles of various SBMs. Additionally, in vitro fiber fermentation trials utilizing fresh fecal inoculum from dogs and cats were conducted to assess the fermentability of the SBM samples. By measuring organic matter disappearance, pH levels, and short-chain fatty acid production, this provides critical insights into how these meals could be utilized in animal diets The successful completion of these deliverables provides essential data that can inform product development and dietary formulations. The findings of this project will serve as a foundational reference for future studies, helping to address misconceptions about soybean meal and demonstrating its value in enhancing pet nutrition. In conclusion, this research not only contributes to the health and well-being of companion animals but also supports the agricultural industry by expanding the potential uses of soybean meal in pet food formulations. By refocusing on the positive aspects of SBM, we aim to unlock new opportunities in the pet food market.

Soybean meal (SBM), a byproduct of soybean oil extraction, is a highly nutritious and cost-effective protein source widely used in livestock feed. As the pet food industry continues to grow and the demand for sustainable, high-quality ingredients increases, SBM is becoming an attractive option for pet food manufacturers. While it's a valuable ingredient, negative perceptions about its anti-nutritional factors and potential to cause flatulence have limited its use in pet food. This project provided a comprehensive analysis of several key characteristics of SBM, including its nutritional composition and fermentability. The findings confirmed that SBM is a reliable protein source due to its consistently high protein and amino acid contents, making it suitable not only for livestock feed but also for pet food production. The study also contributed to a deeper understanding of SBM’s nutritional profile, regarding its oligosaccharide content and levels of anti-nutritional factors. Furthermore, the in vitro fermentation trials shed light on the potential health benefits of SBM in promoting gut health and supporting microbial activity. These findings offer valuable insights that can help address concerns about SBM and promote its use in pet food formulations. Overall, by demonstrating the nutritional value of SBM and addressing misconceptions, this project paves the way for a more positive recognition of SBM as an ingredient in pet food manufacturing. This can in turn lead to increased demand and create greater market opportunities, benefiting soybean farmers through higher sales and increased profitability.
