【摘要】：為了開(kāi)發(fā)斷奶仔豬腸道保護(hù)添加物,本試驗(yàn)通過(guò)在斷奶仔豬飼料中添加1%的焦山楂、焦麥芽、焦神曲來(lái)研究三種添加物分別對(duì)斷奶仔豬腸道作用效果。對(duì)斷奶仔豬飼喂分別添加焦山楂、焦麥芽、焦神曲的飼料和常規(guī)飼料,分別在飼喂后的第7d、第14d選擇平均體重且發(fā)育良好的仔豬進(jìn)行屠宰,采集小腸和胃的組織樣。研究其對(duì)斷奶仔豬胃腸道pH值、腸道組織形態(tài)、胃泌素的分泌等的影響。結(jié)果如下：山楂能有效降低胃腸道pH值,山楂組十二指腸的pH值、空腸的pH值、回腸的pH值、胃的pH值均顯著低于對(duì)照組(P0.05),山楂組的十二指腸和空腸絨毛高度(Villus Height)均顯著低于對(duì)照組(P0.05)。神曲組的十二指腸的pH值、回腸的pH值、胃的pH值均顯著低于對(duì)照組(P0.05),神曲組的十二指腸和回腸隱窩深度(Crypt Depth)均低于對(duì)照組,差異不顯著(p0.05),神曲組回腸VH高于對(duì)照組,差異不顯著(p0.05),神曲組的十二指腸分泌胃泌素細(xì)胞個(gè)數(shù)(Gastrin Cell Number)極顯著大于對(duì)照組(P0.01),神曲組的胃分泌GCN顯著大于對(duì)照組(p0.05)。結(jié)論：仔豬飼料中添加1%的焦神曲能促進(jìn)腸道形態(tài)結(jié)構(gòu)的發(fā)育,修復(fù)損傷的腸道粘膜結(jié)構(gòu),保持黏膜結(jié)構(gòu)的完整性,改善腸道健康,對(duì)仔豬斷奶后起到腸道保護(hù)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.
