This study investigated the effects of dietary supplementation with extruded linseed (ELS) and algae extract (PP) on rabbit carcass and meat quality. Ninety-six rabbit carcasses from two production cycles were analyzed. In the first cycle (C1), rabbits were fed a control diet (1CNT), the same diet supplemented with 5% ELS (1ELS5%), and supplemented with 3.5% ELS and 0.2% PP (1LPP3.5%). In the second cycle (C2), the diets varied in composition and supplementation levels: a different control diet (2CNT), the same diet with 5% ELS (2ELS5%), and with 5% ELS and 0.2% PP (2LPP5%). Meat analyses were performed on et (LTL) muscle for physical properties and on thigh meat (THM) for proximate composition, vitamin E, coenzyme-Q10, cholesterol, fatty acid profile, and mineral content. No significant differences in LTL physical quality were observed in C1, although LTL was brighter in C2 ( < 0.001). THM in C2 had higher fat content ( < 0.001). Dietary supplementation with ELS and PP extract significantly increased polyunsaturated fatty acids (n-3 PUFAs) and improved the n-6/n-3 ratio ( < 0.001) in rabbit meat, demonstrating their positive impact on meat quality.
本研究调查了添加挤压亚麻籽(ELS)和藻类提取物(PP)的日粮对兔胴体和肉质的影响。分析了来自两个生产周期的96只兔胴体。在第一个周期(C1),兔子分别饲喂对照日粮(1CNT)、添加5%ELS的相同日粮(1ELS5%)以及添加3.5%ELS和0.2%PP的日粮(1LPP3.5%)。在第二个周期(C2),日粮的组成和添加水平有所不同:一种不同的对照日粮(2CNT)、添加5%ELS的相同日粮(2ELS5%)以及添加5%ELS和0.2%PP的日粮(2LPP5%)。对腰大肌(LTL)进行物理性质分析,对大腿肉(THM)进行近似成分、维生素E、辅酶Q10、胆固醇、脂肪酸谱和矿物质含量分析。在C1中未观察到LTL物理质量的显著差异,尽管在C2中LTL更亮(<0.001)。C2中的THM脂肪含量更高(<0.001)。日粮中添加ELS和PP提取物显著增加了兔肉中的多不饱和脂肪酸(n-3 PUFAs)并改善了n-6/n-3比值(<0.001),证明了它们对肉质的积极影响。
