Abstract: The black soldier fly (Hermetia illucens) serves as an alternative source of protein in poultry production. However, there is little available information on feeding live black soldier fly larvae (LBSFL) to hens. The present study filled this gap by testing the effect of dietary LBSFL on laying hen performance, feed economy, egg quality, and yolk fatty acid composition. In total, one hundred forty-four 25-week-old Charoen Pokphand Brown laying hens were assigned to four groups. Experimental birds were provided a basal diet supplemented with 0.0 (T1), 10.0 (T2), 20.0 (T3), or 30.0 (T4) g/kg LBSFL. Our results indicated that no effects on body weight gain, egg yield, egg weight, or egg mass (P > 0.05) were observed in any of the dietary LBSFL groups. The addition of 10.0 g/kg LBSFL decreased feed intake, feed conversion ratio, and feed cost (P < 0.05), contrary to two higher doses of LBSFL. Similarly, the egg quality parameters were not influenced (P > 0.05) by the dietary LBSFL except for the egg yolk colour which significantly decreased with increasing LBSFL levels. Furthermore, the values for lightness (L*), redness (a*), and yellowness (b*) of the egg yolk were different (P < 0.05) between the four treatments. Paler egg yolk was found in the 20.0 and 30.0 g/kg LBSFL groups compared to the control group (P < 0.05). Significantly lower deposition of C18:3n6 was found for 30.0 g/kg, whereas there was a significant decrease in deposition of C22:6n3 with all LBSFL groups (P < 0.05). C20:3n6 levels, on the other hand, increased significantly in the 20.0 g/kg LBSFL group (P < 0.05). Thus, feeding LBSFL has no potential to increase the proportion of anti-inflammatory n-3 fatty acids. From an economic point of view, it is advantageous to feed the hens a dose of 10 g/kg LBSFL.
