Mogučnost korištenja alternativnih izvora bjelančevina u hranidbi životinja

As the number of inhabitants in the world is increasing, the consumption of poultry meat and eggs is also increasing, resulting in an increase in poultry production. Such production requires the provision of large quantities of nutrients, including protein, with a good amino acid composition that will meet the needs of fast- growing poultry hybrids and modern laying hens hybrids. Usually, soybeans, whole grains or some of the forms obtained by their processing are used. However, its cost, transportation problems, GMOs, etc. are increasingly leading to research into the possibility of introducing alternative protein sources to poultry feeding. Insects certainly belong here. The nutritional value of insects is very diverse, mainly due to the large number and variability of species. Insects also have a high fatty acids and vitamins content and have proved that they can compete with fish meal, which also used to be the main source of animal protein in animal feed, especially poultry. This paper provides an overview of the possibilities of using alternative sources of protein, or insects, in animal nutrition, and explores the potential use of postharvest biomass as a novel and innovative substrate for the edible insects growing. Postharvest residues contain a huge amount of potential substrate for various insects feeding. Certain insects are capable of transforming nutritionally poor postharvest biomass with low protein content and a high antioxidants and dominant carbohydrates (cellulose and hemicellulose) content into essential nutrients necessary for their growth by modulating their digestive basal and differential gene expression. The conversion of postharvest biomass to insect biomass for animal feed could make a significant contribution to meeting future needs in proteins for the poultry feeding, whose products are used to feed rapidly growing world population.
