Abstract

There is currently interest in integrating insect meal into animal feed. The inclusion of cricket meal at the level of 3% in the diet of chickens demonstrably increased the content of α-tocopherol in the meat and the oxidative stability of the meat. A problematic aspect of the use of cricket meal in mixed feeds for chickens is the profile of fatty acids in the meal and subsequently also in the meat. Its addition causes a decrease in the content of polyunsaturated fatty acids and an increase in the n6/n3 ratio in the meat and an increase in the atherogenic and thrombogenic index, and at the same time a decrease in the value of the HH index, which can lead to the emergence and development of so-called civilization diseases in potential consumers of this meat. In relation to meat quality and human health, a dose higher than 3% cannot be recommended in mixed feeds for chickens. However, the dose of 3% cricket meal is completely negligible compared to the usual content of extracted soybean meal as a source of protein, which reaches up to 30% in chicken feed. On the other hand, the most acceptable meat from the point of view of sensory evaluation was the meat of chickens fed with the highest dose of cricket meal (9%). Therefore, it is advisable to look for a suitable substrate for rearing larvae and adults, which will ensure an improvement of the fatty acid profile of insects or other representatives of the insect class.
