摘要
文章旨在探究茯苓提取物对肉兔血清生化指标和脂质代谢的影响.试验将 400 只生长和健康状况良好 30日龄的断奶仔兔随机分为 4 组,每组 10 个重复,每个重复 10 只.试验日粮分别在基础日粮中添加 0%、0.05%、0.1%和0.2%的茯苓多糖,试验为期 42 d(其中预饲期 5 d,正试期 37 d).试验结果表明,日粮添加 0.2%的茯苓提取物可显著提高肉兔血清总蛋白和白蛋白含量(P＜0.05);日粮添加 0.1%和 0.2%的茯苓提取物可显著降低肉兔血清甘油三酯含量(P＜0.05),显著提高肉兔血清胰岛素含量及谷丙转氨酶活性(P＜0.05);但对肉兔血清瘦素、极低密度脂蛋白含量及碱性磷酸酶和谷草转氨酶活性无显著影响(P＞0.05).日粮添加茯苓提取物可显著降低肉兔肩脂率和肾脂率(P＜0.05),但对肉兔胃周脂率无显著影响(P＞0.05);0.1%和 0.2%添加组显著提高肉兔前腿肌率和后腿肌率(P＜0.05);0.2%添加组显著提高肉兔肝脏CPT-1、CPT-2 和PPAR-α基因表达量(P＜0.05),但对FAS和ACC基因表达量无显著影响(P＞0.05)总之,本试验结果表明,日粮添加茯苓提取物能增强肉兔脂解作用,促进肉兔生长发育.
Abstract
The aim of this study was to investigate the effects of Poria cocos extract on serum biochemical indexes and lipid metabolism of meat rabbits.A total of 400 healthy 30-day-old weaned rabbits were randomly divided into 4 groups with 10 replicates per group and 10 rabbits per replicate.The experimental diet was supplemented with 0%,0.05%,0.1%and 0.2%poria polysaccharides in the base diet,respectively,and the experiment lasted for 42 days(pre-feeding period was 5 days and experimental period was 37 days).The results showed that dietary supplementation of 0.2%poria cocos extract could significantly increase the contents of serum total protein and albumin of meat rabbits(P＜0.05).Dietary supplementation of 0.1%and 0.2%poria cocos extract significantly decreased serum triglyceride content(P＜0.05),and significantly increased serum insulin content and alanine aminotransferase activity of meat rabbits(P＜0.05).However,there were no significant effects on serum leptin and very low density lipoprotein contents and the activities of alkaline phosphatase and ASpartate transaminase in meat rabbits(P＞0.05).Dietary addition of poria cocos extract significantly decreased the percentage of shoulder fat and kidney fat(P＜0.05),but had no significant effect on the percentage of pericardial fat in meat rabbits(P＞0.05).The foreleg muscle percentage and hind leg muscle percentage of meat rabbits in 0.1%and 0.2%supplementation groups were significantly increased(P＜0.05).0.2%supplementation group significantly increased the expressions of CPT-1,CPT-2 and PPAR-α genes in liver of meat rabbits(P＜0.05),but had no significant effects on the expressions of FAS and ACC genes(P＞0.05).In conclusion,the results of this experiment showed that dietary supplementation of Pachycoia extract could enhance lipolysis and promote the growth and development of meat rabbits.
