【摘要】 试验旨在探究发酵桑叶对豫西黑猪血清生化、抗氧化、激素指标水平及盲肠内容物中短链脂肪酸含量的影响。选取60头体况良好、体重相近的豫西黑猪，随机分为对照组（CON组）和试验组（FML组），每组3个重复，每个重复10头猪。对照组饲喂基础日粮，试验组在基础日粮中添加8%的发酵桑叶。试验期共127 d，预试期7 d，正式试验期120 d。结果显示，与CON组相比，FML组豫西黑猪血清低密度脂蛋白胆固醇（LDL-C）含量极显著下降（P<0.01），高密度脂蛋白胆固醇（HDL-C）含量显著上升（P<0.05），游离脂肪酸（FFA）、葡萄糖（GLU）、总胆固醇（TC）和甘油三酯（TG）含量显著下降（P<0.05）;FML组豫西黑猪血清丙二醛（MDA）含量极显著下降（P<0.01），超氧化物歧化酶（SOD）、谷胱甘肽S-转移酶（GST）活性以及总抗氧化能力（TAOC）显著上升（P<0.05）;FML组豫西黑猪血清瘦素（LEP）、脂联素（ADP）水平极显著上升（P<0.01），糖皮质激素（GR）水平显著上升（P<0.05），胰岛素（INS）水平极显著降低（P<0.01）。与CON组相比，FML组豫西黑猪盲肠内容物乙酸含量显著上升（P<0.05）。研究表明，日粮中添加8%发酵桑叶可改善豫西黑猪脂代谢，具有降血糖、血脂的功效，还可提高机体抗氧化能力，调节糖、脂质代谢相关的激素水平。更多还原

【Abstract】 The aim of this experiment was to investigate the effects of fermented mulberry leaves on serum biochemical,antioxidant, hormone indexes and short chain fatty acid content in cecum contents of Yuxi black pigs. Sixty Yuxi black pigs with good body condition and similar body weight were randomly divided into control group(CON group) and experimental group(FML group) with three replicates per group and 10 pigs per replicate. Pigs in CON group were fed a basal diet, and those in FML group were fed a basal diet supplemented with 8% fermented mulberry leaves. The experiment lasted for 127 days, the pre-test period was 7 days, and the formal experiment period was 120 days. The results showed as follows: Compared with CON group, the content of low density lipoprotein cholesterol (LDL-C) in serum of Yuxi black pigs in FML group was extremely decreased(P<0.01), and the content of high density lipoprotein cholesterol(HDL-C) was significantly increased(P<0.05). The contents of free fatty acid(FFA), glucose(GLU), total cholesterol(TC) and triglyceride(TG) were significantly decreased(P<0.05); Serum malondialdehyde(MDA) content of Yuxi black pigs in FML group was extremely decreased(P<0.01), and the activities of superoxide dismutase(SOD), glutathione S-transferase(GST) and total antioxidant capacity(T-AOC) were significantly increased(P<0.05). Serum leptin(LEP) and adiponectin(ADP) level were extremely increased(P<0.01), glucocorticoid(GR) level was significantly increased(P<0.05), and insulin(INS) level was extremely decreased in FML group(P<0.01). Compared with CON group, acetic acid content of cecum contents of Yuxi black pigs in FML group was significantly increased(P<0.05). The study indicates that the addition of 8% fermented mulberry leaves in the diet improved the lipid metabolism of Yuxi black pigs, has the effect of lowering blood sugar and blood lipid, increased the antioxidant capacity of the body, and regulated the levels of hormones related to sugar and lipid metabolism.更多还原
