Palatability and Acceptance of Insect-Based Dry Dog Feed: Insights from Two In-Home Feeding Trials and Owner Evaluation
Edible insects emerge as a sustainable and nutritious alternative protein source due to their
high protein content, nutritional profile, and low environmental footprint. Following regulatory
approval, insect-based pet food products are increasingly entering the market; however,
research on palatability, owner perception, and market positioning remains limited. This study
evaluates the dog’ preference for a dry food formulated with insect protein (25% of
incorporation) and owners’ overall perceptions.
A two-bowl approach across 6 meals in a home-use feeding trial was performed. The first
study compared an insect-based formulation with the dogs’ usual feed (panel segmented by
brand: Purina, Private-Label or Royal Canin)(n=60). The second study compared the insectbased
formulation with a similar poultry-based feed from the same manufacturer(n=100). In
both studies, the owner’s perception regarding the aspect, odour and texture of the product,
as well as the overall impression regarding the animal reaction, was evaluated.
In the first study, overall consumption rates were slightly higher for the regular feed than for
the insect-based formulation, without significant differences. Segment analysis revealed
heterogeneous responses: the insect-based feed showed significantly higher consumption
rates than the private-label brand (p≤0.001), but lower consumption than the premium brands
Purina and Royal Canin (p≤0.001). A large dispersion in consumption rates was also observed
for the insect-based feed, indicating substantial inter-individual variability: some dogs
consumed it enthusiastically, while others showed low acceptance.
In the second study, the poultry-based product showed a significantly higher global
consumption rate(p≤0.001). Despite these differences, owner feedback indicated generally
positive acceptability of the insect-based feed. Appearance received comparatively lower
evaluations, with the dark colour of the kibble being the most frequently mentioned negative
aspect. Overall hedonic scores indicated moderate liking and a general interest among
owners in purchasing insect-based pet food, although opportunities for product optimisation
remain.
