Effect of Black soldier fly defatted meal on the growth performance and carcass yield of Muscovy duck: preliminary results
The aim of this study was to evaluate the effects of different inclusion levels of a partially defatted black soldier fly (Hermetia illucens L.; HI) larva meal on growth performance and carcass yield of Muscovy ducks (Cairina moschata domestica). Three-day-old females broiler Muscovy ducklings (R71 L, Grimaud Freres-France; average live weight:71.32\ub12.70g) were randomly allotted in 32 pens (8 replicates/treatment, 8 birds/replicate), and reared until 48 days of age. The HI larva meal was included substituting corn gluten at increasing level (0, 3, 6 and 9%; HI0, HI3, HI6 and HI9, respectively) in isonitrogenous and isoenergetic diets formulated for 3 feeding phases: starter (1-14 d), grower (14-35 d) and finisher (35-48 d). Live weight (LW), average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) were assessed for each different period and for the whole trial. At day 48, carcass yield was determined in 16 animals per treatment for hot carcass weight (HCW) and cold carcass weight (CCW). Data were analysed by means of one-way ANOVA evaluating the effect of dietary HI inclusion level by polynomial contrasts. Significance was declared at P<0.05. LW did not differ among groups (average final LW: 2515.68\ub192.42g). From 14 to 35 days of age, the ADG showed a quadratic response (P<0.05), but no differences were observed among groups during the starter and finisher periods. The ADFI was never affected, whereas FCR showed a linear response to increasing HI meal levels during starter period (P<0.05), with a minimum for the HI9 group. However, no differences were observed for grower and finisher periods and for the whole trial. HCW and CCW showed a quadratic response to increasing HI larva meal (P<0.05), but no differences were observed for carcass yield. This preliminary investigation indicates that HI larva meal could be a valuable protein source for Muscovy duck, with no negative effect on growth performance and carcass yields
