| Abstract | This was the first experiment testing insect oil from Hermetia illucens in the diet for growing rabbits. The trial was designed to assess the effect of two different oil sources, insect oil or linseed oil, at two inclusion levels in the diet of growing rabbits on fatty acid (FA) profile and oxidative stability in hind leg meat. Four isoprotein and isofibrous diets were formulated with two oil sources (oil from Hermetia illucens or linseed oil) at two inclusion levels (3 or 6%). Rabbits (12×4) were individually caged and experimental diets were fed ad libitum from weaning to 70 days of age, then slaughtered. The hind legs were excised 24 h post mortem from carcass and deboned. The fatty acid profile of hind leg meat was evaluated, and the meat oxidative stability was assessed after 5 days of chilling and 6 weeks of freezing using the thiobarbituric acid (TBA) method. The meat of rabbits fed with insect oil diet was characterized by higher saturated fatty acids and lower unsaturated fatty acids content compared to that of rabbits fed with linseed oil diet. All the FAbased nutritional indexes of meat were more favorable for linseed diet (P<0.001). The oxidative stability of meat was not affected (P>0.05) by lipid source or level after 5 days of chilling, but after 6 weeks of frozen storage, meat from animals fed insect oil presented lower (P<0.001) TBA values than meat from animals fed insect oil. This study showed that if the FA profile of Hemetia illucens oil can be improved, it would be a promising feed ingredient for growing rabbits. Consequently, further research on this topic is required. |
