Abstract
A szerzők az irodalmi összefoglalóban a rovarok és rovartartalmú takarmányok emészthetőségét értékelik a kutya- és macskatakarmányozásban való alkalmazásuk szempontjából. A kereskedelmi forgalomban kapható rovartartalmú kutya- és macskatápok száma folyamatosan nő. A termékek döntően fekete katonalégy (Hermetia illucens) és lisztbogár (Tenebrio molitor) lárváját tartalmazzák. A nyersfehérje in vivo emészthetősége elmarad az in vitro eredményektől és akár 80% alatt is lehet, ami szükségessé teheti a táp esszenciális aminosav tartalmának legalább 10%-kal való kiegészítését. Kitináz enzim hiányában az emészthetőség legfontosabb korlátozó tényezője a rovarok és rovartartalmú tápok kitintartalma. | Background: Insects are novel and sustainable protein sources for dogs and cats. The number of insect-based commercial dog and cat foods continuously increases. Objective: This review aims to evaluate the digestibility of insects and insectbased diets for dogs and cats. Results and conclusions: In the European Union, eight insect species are authorised for animal feed. These are black soldier fly (Hermetia illucens), common housefly (Musca domestica), yellow mealworm (Tenebrio molitor), lesser mealworm (Alphitobius diaperinus), house cricket (Acheta domesticus), banded cricket (Gryllodes sigillatus) and field cricket (Gryllus assimilis) and silkworm (Bombyx mori). Among these black soldier fly (BSF) and yellow mealworm (YM) are produced in the largest quantity and BSF larvae are the most common components of insect-based dog and cat foods. The most important limiting factor of protein digestibility is the chitin content, as insects are not part of the natural diet of dogs and cats, thus, they do not have a chitinase enzyme production. The in vitro crude protein digestibility of BSF larvae (82-90%) and YM larvae (91-92%) containing feeds is high, while the in vivo results in dogs are lower for both insects (BSF larvae: 74-84%; YM larvae: 84%). Most of the studies showed that dry matter, organic matter, and ether extract digestibility values of insect-based dog foods were similar to conventional diets used as a control. Fewer studies are available about cats with lower in vivo crude protein digestibility of insect-containing feeds (BSF larvae: 73.5-79.8; YM larvae: 80.4%). Lower than 80% protein digestibility means that increasing the essential amino acid levels by a minimum of 10% is recommended. The difference in crude protein digestibility of insect species can be explained by the different digestibility of nitrogen compounds (e.g.: lower or higher chitin content) and the amino acid composition. It can be concluded that insect meals are promising alternative sources of conventional dietary protein for dogs and cats. However, more studies are needed with cats and less common insect species such as cockroaches or locusts.
