A 60-d feeding trial was conducted to evaluate the effects of diets supplemented with two concentrations (0% and 0.3%) of black raspberry ( Miquel) fruit by-product (RCFB) on the physicochemical characteristics, oxidative stability, antioxidant capacity, antioxidant enzyme activity, and fatty acid profile of (LL) porcine muscle from Berkshire finishing pigs meat. Results revealed that regardless of the sex, diets supplemented with 0.3% RCFB reduced (p<0.05) the thiobarbituric acid reactive substances (TBARS) expressed as malonaldehyde (MDA) content effectively. A higher antioxidant capacity [2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity] was found (p<0.05) in response to feeding supplemented with 0.3% RCBF for male or female pigs. Moreover, 0.3% RCFB dietary feed increased (p<0.05) the glutathione peroxidase enzyme activities (GPX1) in blood plasma for male or female pigs. However, no influences were observed (p>0.05) on meat color, WHC, shear force, and fatty acid contents while fed diet supplemented with 0% or 0.3% RCFB for male or female pigs. Overall, this study suggests that a diet supplemented with 0.3% RCFB may beneficially affect owing to better oxidative stability, higher antioxidant capacity, and antioxidant enzyme activity (blood plasma) in pigs which could be a promising natural antioxidant without affecting meat quality traits.
进行了一项为期60天的饲养试验，以评估添加两种浓度（0%和0.3%）的黑树莓（Miguel）果实副产物（RCFB）的日粮对伯克夏育肥猪瘦肉（LL）猪肌肉的理化特性、氧化稳定性、抗氧化能力、抗氧化酶活性和脂肪酸组成的影响。结果表明，无论性别如何，添加0.3% RCFB的日粮均能有效降低（p<0.05）以丙二醛（MDA）含量表示的硫代巴比妥酸反应性物质（TBARS）。在雄性或雌性猪中，饲喂添加0.3% RCBF的日粮后，发现抗氧化能力更高[2,2-二苯基-1-苦基肼（DPPH）自由基清除活性]（p<0.05）。此外，0.3% RCFB日粮饲喂的雄性或雌性猪血浆中的谷胱甘肽过氧化物酶活性（GPX1）增加（p<0.05）。然而，对于雄性或雌性猪，饲喂添加0%或0.3% RCFB的日粮时，未观察到对肉色、保水性、剪切力和脂肪酸含量的影响（p>0.05）。总体而言，本研究表明，添加0.3% RCFB的日粮可能会产生有益影响，因为猪具有更好的氧化稳定性、更高的抗氧化能力和抗氧化酶活性（血浆），这可能是一种有前途的天然抗氧化剂，且不会影响肉质性状。
