Innovative scientist – insect protein in dog food

The research was funded by university resources as part of the "Innovative Scientist" competition (for research projects for young post-doctoral scientists), and the results will be published soon. Dr. Eng. Anna Budny-Walczak is currently in the process of writing a scientific article on the topic.

–The possibility of using insect larvae in dog food is very important primarily because of the competitiveness of protein sources. Insect larvae are characterized by a high protein content with a favorable amino acid profile – explains Dr. Budny-Walczak. –The second valuable component is fat, which positions larvae as a valuable alternative to meat in pet food. Additionally, insect farming is more sustainable, uses fewer resources, and generates lower greenhouse gas emissions compared to livestock farming – adds the UPWr scientist.

She explains that producing one kilogram of larvae results in four times less carbon dioxide emissions compared to poultry meat production. Compared to beef, this value is almost forty times lower.

–Moreover, by using protein derived from larvae, we do not deal with animal-derived waste, as the larvae are consumed whole – she says.

Research on the digestibility of insect larvae protein will also help develop formulas for high-quality pet foods, which is an important aspect of dietary prevention for animals.

– My research has shown that the amino acid composition of larvae protein is close to that of animal-derived protein, thus meeting the needs of dogs or cats. It can also be a solution for animals with food allergies, which have become a significant medical problem recently. The fatty acid content in insect larvae is also highly beneficial for carnivorous animals – enumerates the UPWr scientist.

In stores, pet foods containing insect larvae have been available for some time. Dr. Anna Budny-Walczak says they can be used but should be introduced cautiously. –  All pet food, even meat-based, must be introduced properly. If a pet owner is unsure of their choice due to the animal's health, they should seek advice from a zoo dietitian – she emphasizes.

The research conducted under the "Innovative Scientist" project forms the basis for a broader project for which the UPWr scientist plans to apply for funding from the National Science Centre.

  Disgusted Europe. Will insects become our staple food?

  By 2050 people will have to produce 2.5 times more food than now. The problem could be solved by the use of edible insects – tasty, healthy and ecological in breeding. They are being researched by Anna Żołnierczyk PhD from the Department of Chemistry.
