In recent decades, the scientific community has set great hopes on the larval forms of the Black Soldier Fly (Hermetia illucens) as an innovative source of animal protein and fat. However, the possibility of utilisation of some other products (secondary ones) from the life cycle of this insect species (pupal shell and fly bodies) remains unexplored. In this experiment, we used two groups of broiler chickens, one fed standard starter feed (the control group) and the other fed starter with the addition of pupal shells and dried imago (experimental group). The experimental diet was fed from 3 weeks up to 6 weeks of age of the birds. The average live weight recorded in dynamics during the trial period were significantly higher in the experimental group, compared to the control one. During the intensive phase of growth (3-4 weeks of age) higher values of the weight gain and lower values of the ratio feed/gain and feed/weight were recorded (P<0.05) in the experimental group. The carcass analysis showed higher values of live weight before slaughter, the carcass weight, dressing percentage, breast and heart (absolute and relative values), legs (absolute values), back (absolute values) and wings (absolute values), in the experimental group. Significantly higher values of the losses and percentage of the red meat, were recorded in the control group.
