Study Indicates Good Acceptance of Insect-Based Wet Food by Dogs

Ingredients derived from insects are being explored as alternative sources of protein in pet nutrition. 
 

In addition to their functional potential, these raw materials have attracted industry interest due to their versatility in both wet and dry formulations.
 

A recent study evaluated the acceptance of wet dog food containing insect-based ingredients marketed under the PureeX and ProteinX brands, developed by Protix. 
 

The results indicated that both the all-insect-based diet and the hybrid formulation—combining insects and chicken—were readily consumed by the participating animals.

How the study was conducted

The trial included 170 small and medium-sized dogs, all living in homes. According to the technical summary, these categories were selected because they are often considered more selective with regard to food.

Two diets were evaluated. The first consisted exclusively of ingredients derived from the black soldier fly larva (Hermetia illucens), combining PureeX — described as a minimally processed ingredient — and ProteinX, an insect meal. 
 

The second was a hybrid formulation that combined the same insect ingredients with fresh chicken.
 

Each caregiver offered one of the diets for two consecutive days and then switched to the other formula for another two days. 
 

During the testing period, participants were not informed about the composition of the products.
 

At the end of each stage, those in charge evaluated the dogs' consumption. According to the report, both formulations were considered highly acceptable, with no statistically significant difference in intake between the 100% insect diet and the hybrid diet.

Behavioral assessment and sensory perception

In addition to the volume consumed, the study analyzed the dogs' behavior before, during, and after meals. 
 

Among the responses associated with positive acceptance were wagging the tail before the food was offered, consuming the entire portion, and licking the lips after the meal. These behaviors were recorded in both diets.
 

Those responsible also evaluated sensory attributes such as texture, aroma, and appearance. Both formulations received an average score of seven, on a scale of zero to ten, for these criteria.
 

When asked for a recommendation, 82% said they would recommend a diet entirely based on insects, while 81% said they would recommend a hybrid formulation with chicken.
 

According to the manufacturer, PureeX is indicated for use in moist foods and can also be included in dry extruded formulations, being available in fresh and frozen versions. ProteinX, on the other hand, is marketed as a protein ingredient in flour form.

Alternative protein on the rise

Insect proteins have been studied as alternatives to traditional sources, with the potential to contribute to formulations seeking ingredient diversification. 
 

In addition to nutritional profile, manufacturers highlight functional and sustainability aspects as differentiating factors of this type of raw material.

FAQ about wet food with insect protein

Do dogs readily accept food containing insect protein?
According to the study, both the 100% insect formulation and the hybrid with chicken were readily consumed.

Was there a difference in consumption between the diets tested?
No. The report indicates that no significant difference in intake was observed.
 

Can insect protein replace traditional proteins?
It is being studied as an alternative source, but the choice of diet should always be made in consultation with a veterinarian.
