Lamb meat has become very popular with consumers in recent years due to its nutritional benefits. As a lean red meat, lamb is an important natural source of polyunsaturated and saturated fatty acids, which can be modified by adjustments in livestock feed. This study used proteomic and metabolic analyses to compare a basal ration supplemented with either mulberry silage or corn silage. Supplementation with mulberry silage led to a reduction in subcutaneous carcass fatness compared with corn silage. Additionally, changes in the proteome associated with fatty acid metabolism and oxidation resulted in decreased levels of saturated and trans fatty acids, while significantly increasing the levels of α-linolenic acid (ALA) and oleic acid and reducing linoleic acid content.
近年来,羔羊肉因其营养价值而深受消费者喜爱。作为一种瘦肉型红肉,羊肉是多不饱和脂肪酸和饱和脂肪酸的重要天然来源,这些脂肪酸可通过调整牲畜饲料来改变。本研究采用蛋白质组学和代谢分析方法,比较了添加桑椹青贮饲料或玉米青贮饲料的基础日粮。与玉米青贮饲料相比,添加桑椹青贮饲料可降低胴体皮下脂肪含量。此外,与脂肪酸代谢和氧化相关的蛋白质组变化导致饱和脂肪酸和反式脂肪酸水平降低,同时显著提高了α-亚麻酸(ALA)和油酸水平,并降低了亚油酸含量。
