菊粉和刺五加提取物对早期断奶仔猪生长性能、血液指标和肠道形态的影响

Effects of Inulin and Acanthopanax senticosus Extract on Growth Performance,Serum Biochemical Parameters,and Intestinal Morphology of Early-weaned Piglets

试验选用120头21日龄5.64kg左右的三元杂交断奶仔猪,分别饲喂基础日粮(对照组)、基础日粮+抗生素(抗生素组)和基础日粮+5%菊粉+0.1%刺五加提取物(实验组),试验期为14d,观察日粮中复合添加菊粉和刺五加(AS)提取物对早期断奶仔猪生长性能、血液生化指标和肠道形态的影响。试验结果表明,实验组与对照组相比,仔猪日增重(ADG)显著提高(P<0.05),而料肉比(F/G)则显著降低(P<0.05),但平均日采食量(ADFI)差异不显著(P>0.05);实验组仔猪血清中血糖(GLU)、低密度脂蛋白(LDL)、乳酸脱氢酶(LDH)和尿素氮(BUN)与对照组差异不显著(P>0.05),但试验第14d,碱性磷酸酶(ALP)、超氧化物歧化酶(SOD)和还原型谷胱甘肽(GSH)浓度均显著高于对照组(P<0.05);实验组仔猪十二指肠和回肠的隐窝深度显著高于对照组(P<0.05),空肠和回肠的绒毛高度显著高于对照组(P<0.05)。试验显示,日粮中添加菊粉和刺五加提取物对提高早期断奶仔猪的生长性能、改善小肠消化和吸收功能有重要作用。

One hundred and twenty three-way cross piglets weaned at 21 d with initial average weight 5.64±0.46 kg were selected in the experiment.The piglets were fed with the following diets for 14 days：1）NC（Control diet without antibiotics）,2）PC（Control diet＋Antibiotics）,and 3）E group（Control diet＋5% Inulin＋0.1% Acanthopanax senticosus（AS）extract）.Effects of diets supplement with Inulin and AS extract on growth performance,serum biochemical parameters,antioxidant function,and intestinal morphology were observed.The results showed that,ADG of E group were significantly improved（P0.05）and ratio of feed and growth（F/G）were significantly decreased（P0.05）compared to the NC,while no significant difference were observed in ADFI（P0.05）.There were no significant differences in serum GLU,LDL,LDH and BUN between NC and E group（P0.05）,while on 14 d,ALP,SOD and GSH were significantly improved（P0.05）.Compared to the NC,Crypt depth of duodenum and ileum and villus height of jejunum and ileum of E group were significantly improved（P0.05）.This study demonstrated that supplement with compound of Inulin and AS extract had important functions on growth performance and digestion of small intestine of early-weaned piglets.
