The search for sustainable and nutritionally adequate protein sources in pet food has led researchers to evaluate plant-based alternatives such as canola meal, already common in livestock and poultry diets. Gajda and colleagues (2024) investigated its potential in adult canine nutrition, examining digestibility, stool quality, and palatability when canola meal was added at 5% and 10% inclusion levels to a high-protein, chicken-based diet.
The study substituted canola meal for pea protein to maintain consistent levels of protein, fat, and crude fiber. Thirty dogs participated in a standard two-bowl palatability test, while digestibility and stool quality were evaluated in smaller cohorts through acclimation and fecal collection phases. Stool consistency was rated on a scale from 1 (diarrhea) to 5 (hard formed).
Results showed no statistically significant differences in protein digestibility (all above 84%), fat digestibility (all above 92%), or stool quality (average 3.4–3.5 across diets). Palatability was similar between canola-based and control diets, though dogs showed a preference for the 10% inclusion diet compared to the 5% version. Importantly, there were no signs of digestive intolerance or reduced acceptability, confirming canola meal as a viable dietary component for dogs.
This research supports canola meal as an AAFCO-approved, sustainable protein source that can be incorporated into commercial dog diets without compromising nutritional adequacy, digestion, or palatability. As demand grows for sustainable alternatives to traditional animal proteins, canola meal may offer a promising option for balanced, environmentally conscious canine nutrition.
