The effect of incorporating mealworm frass (MWF) in the diets of growing Gabaly rabbits on nutrient digestibility, live body weight and gain, properties of the carcass, and blood parameters was investigated. Fifty-two Gabaly rabbits (6 weeks old) were selected after weaning and divided into four groups in a random fashion (13 rabbits/group) based on their weights (653 ± 15 g). The experimental period extended from 6 to 15 weeks of age. Four isocaloric, isonitrogenous and isofibrous diets in pellet shape were formulated. Mealworm frass (MWF) was incorporated at levels of 0, 1, 2, and 3 % for rabbit groups: G0 (as a control), G1, G2, and G3. At the end of the feeding experiment period (15 weeks of age), digestibility trials were conducted to determine the nutrient digestibility and nutrition values of the experimental diets. Three rabbits were slaughtered from each group to determine the carcass traits and some blood parameters. The chemical composition MWF was recorded as dry matter 87.08-, organic matter 84.98-, crude protein 22.59-, crude fibre 17.62-, ether extract 2.78-, ash17.24-, and nitrogen-free extract 41.99- %. The digestibility of dry matter, organic matter, crude protein, and crude fibre improved (P
