A partial substitution (25 or 50%) of dietary protein with Tenebrio molitor (TM) and Hermetia illucens (HI) meals as protein sources in the diet of Barbary partridge (Alectoris barbara) has been tested in terms of raw and cooked meat quality. Twelve partridges per feeding group (control - SBM, HI25, HI50, TM25 and TM50) were slaughtered. The peeled carcasses of the HI25, HI50, TM25 and TM50 groups were heavier than those of the SBM group, both raw and cooked. The pH, color and shear force of the raw meat were not affected to any greater extent by the diet, whereas the presence of insect meal seemed to increase the yellowness index of the cooked meat. The proximate composition was unaffected by both the species and the level of insect meal, although the fatty acid profile was changed considerably. The HI and TM groups had significantly higher C18:1n-9 and lower C16:0 contents than SBM. Furthermore, Hermetia illucens, added as 50% of the dietary protein, induced a significant increase in C12:0 and C16:1n-7. As a result, the highest AI and TI were obtained for the HI50 diet (0.38 and 0.75, respectively), whereas the TM groups both had intermediate AI values (around 0.35) and the lowest TI (0.67). Finally, the cholesterol content of the birds was not affected by insect inclusion in the feeds.

饲料中的Hermetia illucens黄粉虫幼虫膳食对affected的肉质的影响

黄粉虫Tenebrio molitor)和伊米氏Hermetia illucens)膳食部分替代(25%或50%)膳食蛋白质作为巴巴里part(Alectoris barbara)饮食中的蛋白质来源)已通过生肉和熟肉质量的测试。每个饲喂组十二只part(对照组-SBM,HI25,HI50,TM25和TM50)被屠宰。HI25,HI50,TM25和TM50组的去皮car体比SBM组的生和熟都重。饮食对生肉的pH,颜色和剪切力没有太大的影响,而虫粉的存在似乎增加了熟肉的黄度指数。尽管脂肪酸的分布发生了很大的变化,但其近乎组成并未受到种类和虫粉含量的影响。HI和TM组的C18:1n-9含量明显高于SBM,而C16:0含量则明显低于SBM。此外,Hermetia illucens,以50%的饮食蛋白质形式添加时,会导致C12:0和C16:1n-7显着增加。结果,HI50日粮的AI和TI最高(分别为0.38和0.75),而TM组的AI值均处于中间水平(约0.35),而TI最低(0.67)。最后,家禽的胆固醇含量不受饲料中虫害的影响。
