The objective of this study was to compare the effect of the dietary beer trub, alone or in combination with linseed, on meat quality, oxidative status and cholesterol content of rabbit. Eighty New Zealand White rabbits were divided at weaning (30 d) into four dietary groups: control (C) fed a standard diet, trub (T, 2% of lyophilized trub), linseed (L, 3% of extruded linseed), and trub-linseed in combination (TL, 2% of lyophilized trub and 3% of extruded linseed). At slaughtering (80 d) the oxidative parameters of blood and quality of Longissimus thoracis et lumborum were analysed. The in vivo lipid oxidation was similar in the supplemental groups, whereas it was higher in T, L and TL meat compared to C. Trub supplementation in rabbit diets slightly affected the fatty acid profile (MUFA) and worsened the oxidative status of meat, and its inclusion in combination with linseed did not counteract the oxidative instability induced by the higher PUFA content.
本研究旨在比较单独或结合亚麻籽的啤酒糟饲料对兔肉品质、氧化状态和胆固醇含量的影响。80 只新西兰白兔在断奶(30 日龄)时被分为 4 个饮食组:对照组(C)饲喂标准饮食,啤酒糟组(T,2%冻干啤酒糟),亚麻籽组(L,3%膨化亚麻籽)和啤酒糟-亚麻籽联合组(TL,2%冻干啤酒糟和 3%膨化亚麻籽)。在屠宰时(80 日龄),分析了血液的氧化参数和背最长肌的肉品质。补充组的体内脂质氧化相似,但 T、L 和 TL 肉中的氧化程度高于 C。在兔饲料中添加啤酒糟轻微影响了脂肪酸谱(MUFA),并使肉的氧化状态恶化,并且与亚麻籽联合添加并没有抵消由于较高的多不饱和脂肪酸含量引起的氧化不稳定性。
