摘要: 本试验旨在研究水牛初乳粉、常乳粉对0~72 h新生仔猪小肠组织形态结构发育的影响。试验以新生仔猪为研究对象,分别饲喂水牛初乳粉(SCR组)、水牛常乳粉(SC组)、葡萄糖盐水(PY组),以0日龄新生仔猪(XD组)作为对照。结果表明,水牛初乳粉使新生仔猪小肠绒毛密集、粗壮、排列整齐,肌层厚度、固有膜厚度增加。SCR组与XD组相比,十二指肠绒毛高度、绒毛宽度、固有膜厚度和空肠绒毛宽度、肌层厚度及回肠绒毛高度均极显著增加(P<0.01);SCR组与PY组相比,十二指肠绒毛宽度及空肠绒毛宽度、肌层厚度均极显著增加(P<0.01)。水牛常乳粉使新生仔猪小肠黏膜受损,黏膜上皮脱落,肌层变薄,固有膜裸露,小肠绒毛坍塌、稀疏变短。SC组与XD组相比,十二指肠肌层厚度和空肠绒毛高度、绒毛宽度、肌层厚度、固有膜厚度及回肠绒毛宽度、固有膜厚度均呈降低趋势,但差异均不显著(P>0.05);SC组与PY组相比,空肠肌层厚度显著降低(P<0.05)。综上所述,水牛初乳粉能显著促进新生仔猪小肠发育,尤其对空肠影响最大,其次为十二指肠,而对回肠的影响相对较小;水牛常乳粉不能对新生仔猪肠黏膜形成保护并促进其生长发育,在新生仔猪最初发育的72 h内其价值不如葡萄糖盐水。

Abstract: The experiment was conducted to study the effect of colostrum powder and mature milk powder of buffalo on small intestinal tissue morphology development of newborn piglet.Newborn piglets within 72 h in treatments group were fed with buffalo colostrum powder (SCR group),buffalo mature milk powder (SC group) and glucose saline (PY group), respectively. 0-day-old newborn piglets as control (XD group).The results showed that intestinal villi of newborn piglets were densely,stout,arranged neatly, the thickness of muscular layer and membranaepropria were increased after taking buffalo colostrum powder. Compared with XD group,villus height,villus width,as well as membranaepropria thickness of duodenum,villus width and muscular layer thickness of jejunum,also and villus height of ileum were extremely significantly increased in SCR group (P<0.01).The villus width of duodenum, villus width and muscular layer thickness of jejunum in SCR group were extremely significantly increased than that in PY group (P<0.01).Buffalo mature milk powder caused damage to newborn piglets’ intestinal mucosal,including epithelial sheded,muscle layer thinned,membranaepropria naked and intestinal villi collapsed. Compared with XD group,the muscular layer thickness of duodenum,villus height, villus width, muscular layer thickness and membranaepropria thickness of jejunum, villus width and membranaepropria thickness of ileum in SC group were reduced,but there were no significant differences among them (P>0.05).However,the muscular layer thickness of jejunum in SC group was significantly decreased than that in PY group (P<0.05). In summary,the development of newborn piglets’ intestinal was promoted by feeding with buffalo colostrum powder. The biggest influence on jejunum,followed by duodenum,ileum. There was no effect on protecting intestinal mucosa and promoting its development by buffalo mature milk powder.The value of buffalo mature milk powder was less than glucose saline for development of newborn piglets within 72 h.
