Abstract:
The present research studied for the first time the potential application of the fat derived from
the black soldier fly larvae fat (BSLF) in substitution to the soybean oil in the diet for broiler
chickens: growth performances, feed-choice, blood traits, carcass characteristics and meat quality
were considered in this study. A total of 150 male broiler chicks (Ross 308) at one-day of age
were randomly allotted to 3 dietary treatments (5 replicates and 10 birds/pen): a basal control
diet (C group), and the same diet in which the soybean oil was replaced by 50% (CH group) or
100% (H group) BSLF. Growth performances, feed-choice test, blood traits and slaughtering performances
were not influenced by diets. Independently of BSLF inclusion, broiler chickens breast
meat had also similar crude protein and ether extract contents and displayed similar thawing
loss. Furthermore, pH, L, a, b colour values, and drip loss were unaffected by dietary treatments
both at 0 and 9 days of refrigerated storage. As expected, the fatty acid profile of broiler
chickens breast was greatly affected by BSLF inclusion level. With increasing BSLF inclusion rate,
the proportion of SFA increased (32.2, 37.8, 43.5% for C, CH and H breast meat, respectively,
p<.001) to the detriment of the PUFA fraction (22.7, 23.0, 22.9% for C, CH and H breast meat,
respectively, p<.001). On the contrary, MUFA fraction was unaffected. BSLF inclusion guaranteed
satisfactory productive performances, carcass traits and overall meat quality, thus suggesting
that BSLF could be a promising new feed ingredient for chickens.
