The inclusion of Black Soldier Fly (BSF) fat or extruded linseed (LIN) in diets for growing rabbits on meat fatty acids (FA), dimethyl acetals (DMA), oxidative stability and color was evaluated. Forty-eight rabbits with 35 days of age were individually housed, fed one of 4 diets (LIN-Low, 30 g/kg of fat from LIN; LIN-High, 60 g/kg of fat from LIN; BSF-Low, 30 g/kg of BSF fat; BSF-High, 60 g/kg of BSF fat) and slaughtered after 5 weeks. Diets with BSF reduced the intramuscular FA but increased the 12:0 and 14:0 in meat compared to LIN, whereas LIN diets increased the 18:3n-3 deposition in meat. Regressions between FA intake and FA meat concentration indicate that the deposition of 12:0 and 14:0 in the meat of BSF-fed rabbits was lower than the deposition of n-3 PUFA in the meat of LIN-fed rabbits. Overall, lipid profiles of meat from BSF-fed rabbits were less healthy, but meat from LIN-fed rabbits was the more susceptible to oxidation.

将黑士兵蝇(Hermetia illucens L.)幼虫脂肪或膨松亚麻籽掺入生长中的兔子的日粮中,及其对肉质性状的影响,包括详细的脂肪酸组成

评估了黑肉蝇(BSF)脂肪或挤压亚麻籽(LIN)在用于成兔的日粮中的肉脂肪酸(FA),二甲基乙缩醛(DMA)的含量,氧化稳定性和颜色。分别饲养48只35天大的兔子,喂食4种饮食之一(低(LIN-Low,来自LIN的脂肪为30克/千克;高-LIN,来自LIN的脂肪为60克/千克;低BSF,30千克) g / kg BSF脂肪; BSF高,60 g / kg BSF脂肪),并在5周后屠宰。与LIN相比,使用BSF的饮食减少了肌肉中的FA,但增加了肉中的12:0和14:0,而LIN饮食增加了18:3n-3在肉中的沉积。FA摄入量与FA肉浓度之间的回归表明,用BSF喂养的兔子的肉中12:0和14:0的沉积低于LIN喂养的兔子的肉中n-3 PUFA的沉积。全面的,
