Introduction. Few studies on the effects of live larvae provision in poultry have been previously conducted [1,2,3]. However, trials on the long-term provision of live larvae in chicken reared for meat consumption have never been performed before. This study evaluated the impact of Black Soldier Fly (BSF) live larvae provision on growth performance and larvae consumption behavior of intermediate-growing strains. Material and methods. A total of 240 Label naked neck birds were reared from 21 to 82 days of age, and four experimental groups (10 birds/pen, 6 replicates/treatment) were considered according to the birds’ gender and larvae provision. Experimental groups were fed 10% supplementation of BSF live larvae based on the daily feed intake. The live weight (LW), feed conversion ratio (FCR), average daily feed intake (ADFI) and average daily gain (ADG) were evaluated considering two periods: 21-35d and 35-82d. The larvae were provided daily and consumption times were analyzed considering periods of 10 days (5 time frame-T1,T2,T3,T4,T5). Data were analyzed by means of a GLMM (SPSS software, P
