The fermented feed has been identified as a potential alternative to antibiotics in feeds that markedly affects gut health and growth performance of pigs. Two recent studies performed in our laboratory investigated that the fermented corn–soybean meal (fermented feed, FF) improved the gut health of pigs. This study was conducted to determine the effect of a FF on the carcass, meat quality, muscle fatty acids profile, muscle amino acid and antioxidant ability of grower-finisher pigs. In this study, a total of 48 crossbred barrows (Duroc × Landrace × Large White) were randomly divided into 2 treatments with unfermented corn–soybean diet (Ctrl) and FF diet. Compared with control pigs fed a standard diet, the results showed that FF significantly increased the muscle colour of redness and significantly reduced muscle moisture loss rate. Furthermore, FF significantly increased the content of aromatic amino acids such as aspartic acid, glutamic acid and alanine. More importantly, FF increased monounsaturated fatty acid and polyunsaturated fatty acid content. Collectively, FF could be a promising feed strategy in improving meat quality and nutritional value in grower-finisher pig.

发酵玉米豆粕对生长肥育猪胴体及肉质的影响


发酵饲料已被确定为饲料中抗生素的潜在替代品，可显着影响猪的肠道健康和生长性能。我们实验室最近进行的两项研究表明，发酵玉米豆粕（发酵饲料，FF）可以改善猪的肠道健康。本研究旨在确定 FF 对生长肥育猪的胴体、肉质、肌肉脂肪酸谱、肌肉氨基酸和抗氧化能力的影响。在本研究中，共有48只杂交阉猪（杜洛克×长白×大白）随机分为2个处理，分别采用未发酵玉米-大豆日粮（Ctrl）和FF日粮。与饲喂标准日粮的对照猪相比，结果显示，FF显着增加了肌肉颜色的红度，并显着降低了肌肉水分流失率。此外，FF还显着增加了天冬氨酸、谷氨酸和丙氨酸等芳香族氨基酸的含量。更重要的是，FF增加了单不饱和脂肪酸和多不饱和脂肪酸的含量。总的来说，FF 可能是一种有前景的饲料策略，可提高生长肥育猪的肉质和营养价值。
