摘  要：
本试验旨在研究吡咯喹啉醌(PQQ)对高能低蛋白质饲粮蛋鸡生产性能、蛋品质、血浆脂质代谢及抗氧化能力的影响。选用29周龄海兰褐产蛋鸡288只,随机分为4组,每组6个重复,每个重复12只鸡。Ⅰ组为对照组,饲喂基础饲粮(代谢能11.03 MJ/kg,粗蛋白质16.20%);Ⅱ组为病理模型组,饲喂高能低蛋白质饲粮(代谢能12.75 MJ/kg,粗蛋白质13.00%);Ⅲ和Ⅳ组为PQQ预防组,分别在Ⅱ组基础上添加0.08和0.16 mg/kg的PQQ。试验期4周。结果表明:1)与对照组相比,高能低蛋白质饲粮诱导蛋鸡发生脂肪肝,表现为Ⅱ组肝脂率显著升高(P<0.05),血浆甘油三酯(TG)、总胆固醇(TC)和低密度脂蛋白胆固醇(LDL-C)含量显著升高(P<0.05)。2)饲粮添加PQQ可显著降低高能低蛋白质饲粮引起的蛋鸡平均日采食量和料蛋比的升高(P<0.05),显著抑制蛋白高度、哈氏单位和蛋黄颜色的降低(P<0.05),显著抑制血浆TG、TC、LDL-C含量和乳酸脱氢酶活性的升高(P<0.05),达到与对照组相当的水平。3)饲粮添加PQQ可显著抑制高能低蛋白质饲粮引起的血浆超氧化物歧化酶活性的降低和丙二醛含量的升高(P<0.05)。由此可见,饲粮添加PQQ可降低肝脏内脂肪含量,改善蛋鸡脂质代谢和机体抗氧化能力。

摘  要：
This experiment was conducted to investigate the effects of pyrroloquinoline quinine(PQQ) on performance,egg quality,plasma lipid metabolism and antioxidant ability of laying hens fed high-energy low-protein diets.Two hundred and eighty-eight Hy-Line brown laying hens aged 29 weeks were randomly divided into 4 groups with 6 replicates per group and 12 hens per replicate.Hens in group Ⅰ(control group) were fed a basal diet(metabolic energy 11.03 MJ/kg;crude protein 16.2%),hens in group Ⅱ(pathological model control group) were fed a high-energy low-protein diet(metabolic energy 12.75 MJ/kg;crude protein13.0%),and hens in groups Ⅲ and Ⅳ were fed the high-energy low-protein diet(the same as group Ⅱ)supplemented with 0.08 and 0.16 mg/kg PQQ,respectively.The experiment lasted for 4 weeks.The results showed as follows:1) compared with the control group,the high-energy low-protein diet induced fatty liver,the liver fat rate in group Ⅱ was significantly increased(P <0.05),and the contents of triglyceride(TG),total cholesterol(TC) and low-density lipoprotein cholesterol(LDL-C) in plasma in group Ⅱ were significantly increased(P <0.05).2) Dietary PQQ could significantly decrease the increase of average daily feed intake and the ratio of feed to egg of laying hens fed high-energy low-protein diets(P <0.05),it could significantly inhibit the decrease of albumen height,Haugh unit and yolk color and the increase of the contents of TG,TC and LDL-C and lactate dehydrogenase(LDH) activity in plasma(P <0.05),and all the above indexes could get the same levels as control group.3) Dietary PQQ could significantly inhibit the decrease of plasma superoxide dismutase activity and the increase of plasma malondialdehyde content of laying hens fed highenergy low-protein diets(P <0.05).In conclusion,dietary PQQ can decrease the liver fat content,improve the lipid metabolism and antioxidant ability of laying hens.
