摘要:

试验选用120头21日龄5.64 kg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14 d,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14天,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。

Abstract:

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 (P<0.05) and ratio of feed and growth (F/G) were significantly decreased (P<0.05) compared to the NC, while no significant difference were observed in ADFI (P>0.05). There were no significant differences in serum GLU, LDL, LDH and BUN between NC and E group (P>0.05), while on 14 d, ALP, SOD and GSH were significantly improved (P<0.05). Compared to the NC, Crypt depth of duodenum and ileum and villus height of jejunum and ileum of E group were significantly improved (P<0.05). 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.
