【摘要】：为了开发断奶仔猪肠道保护添加物,本试验通过在断奶仔猪饲料中添加1%的焦山楂、焦麦芽、焦神曲来研究三种添加物分别对断奶仔猪肠道作用效果。对断奶仔猪饲喂分别添加焦山楂、焦麦芽、焦神曲的饲料和常规饲料,分别在饲喂后的第7d、第14d选择平均体重且发育良好的仔猪进行屠宰,采集小肠和胃的组织样。研究其对断奶仔猪胃肠道pH值、肠道组织形态、胃泌素的分泌等的影响。结果如下：山楂能有效降低胃肠道pH值,山楂组十二指肠的pH值、空肠的pH值、回肠的pH值、胃的pH值均显著低于对照组(P0.05),山楂组的十二指肠和空肠绒毛高度(Villus Height)均显著低于对照组(P0.05)。神曲组的十二指肠的pH值、回肠的pH值、胃的pH值均显著低于对照组(P0.05),神曲组的十二指肠和回肠隐窝深度(Crypt Depth)均低于对照组,差异不显著(p0.05),神曲组回肠VH高于对照组,差异不显著(p0.05),神曲组的十二指肠分泌胃泌素细胞个数(Gastrin Cell Number)极显著大于对照组(P0.01),神曲组的胃分泌GCN显著大于对照组(p0.05)。结论：仔猪饲料中添加1%的焦神曲能促进肠道形态结构的发育,修复损伤的肠道粘膜结构,保持黏膜结构的完整性,改善肠道健康,对仔猪断奶后起到肠道保护作用。
[Abstract]:In order to develop the intestinal protective additives of weaning piglets, the effects of the three additives on the intestinal tract of weaned piglets were studied by adding 1% Hawthorn, pyromalt and Jiao Shenqu into weaning piglets' feed. Weaned piglets were fed with the diets of Hawthorn, Jiao malt, Jiao Shenqu respectively. The piglets with average body weight and well-developed piglets were slaughtered on the 7th and 14th day after feeding, and the tissues of small intestine and stomach were collected. To study the effects of Gastrointestinal pH, intestinal tissue morphology and gastrin secretion in weaned piglets. The results are as follows: Hawthorn can effectively reduce the pH value of gastrointestinal tract, the pH value of duodenum, jejunum and ileum in Hawthorn group. The pH value of stomach was significantly lower than that of control group (P 0.05), and the villus Height of duodenum and jejunum in Hawthorn group was significantly lower than that of control group (P 0.05). The pH value of duodenum, ileum and stomach in Shenqu group was significantly lower than that in control group (P 0.05), and the depth of duodenum and ileum crypt in Shenqu group was lower than that in control group (P 0.05). The ileum VH in Shenqu group was higher than that in control group. The number of gastrin Cell in the Shenqu group was significantly higher than that in the control group (P 0.01), and the gastric secretion GCN in the Shenqu group was significantly higher than that in the control group (P 0.05). Conclusion: adding 1% scorchenqu into piglets diet can promote the development of intestinal morphology, repair the damaged intestinal mucosal structure, maintain the integrity of mucosal structure, improve intestinal health and protect the intestine after weaning.
