| 摘 要： | 本试验旨在研究不同纤维源对成年扬州鹅肠道组织形态变化的影响。选用18只健康、体重相近的25周龄扬州鹅公鹅,随机分为3组,即:稻壳粉组、苜蓿草粉组、羊草粉组,每组6只。试验期28 d,试验期末将试验鹅处死并留取各肠段组织,称重并观察肠道组织形态。结果表明:①不同纤维源对十二指肠和空肠长度影响差异不显著(P>0.05),稻壳草粉组回肠长度显著高于苜蓿草粉组与羊草粉组(P<0.05),苜蓿草粉组与羊草粉组差异不显著(P>0.05)。②稻壳粉组十二指肠绒毛高度、绒毛宽度、隐窝深度、肌层厚度均显著高于苜蓿草粉组与羊草粉组(P<0.05),其中苜蓿草粉组隐窝深度、V/C与羊草粉组差异显著(P<0.05);稻壳粉组与羊草粉组空肠绒毛高度显著高于苜蓿草粉组(P<0.05),隐窝深度显著低于苜蓿草粉组(P<0.05),稻壳粉组与羊草粉组间均差异不显著(P>0.05),稻壳粉组肌层厚度显著高于苜蓿草粉组(P<0.05);羊草粉组回肠绒毛高度显著高于苜蓿草粉组与稻壳粉组(P<0.05),3组间绒毛宽度差异显著(P<0.05),且以稻壳粉组最大,羊草粉组V/C显著高于苜蓿草粉组和稻壳粉组(P<0.05),羊草粉组肌层厚度显著低于苜蓿草粉组与稻壳草粉组(P<0.05)。由此可知,不同纤维源可显著影响25周龄扬州鹅肠道组织形态。

| Abstract: | This experiment was conducted to investigate the effects of different dietary fiber sources on intestine tissue morphology changes of adult Yangzhou geese.Eighteen Yangzhou geese with 25 weeks old were selected and randomly divided into 3 groups with 6 geese per group, namely:Rice husk meal group, alfalfa meal group and Chinese wildrye group.At the end of the test, all geese were weighed, slaughtered and intestinal tract were collected to observe intestine tissue morphology.The results showed as follows:① No significant differences were found in the length of the duodenum and jejunum among three groups (P>0.05), ileum length of rice husk meal group was significantly higher than of alfalfa meal and Chinese wildrye groups (P<0.05), but no significant differences were found between alfalfa meal group and Chinese wildrye group (P>0.05).② Duodenal villus height, villus width, crypt depth and muscle thickness of rice husk meal group were significantly higher than that of alfalfa meal group and Chinese wildrye group (P<0.05), where the crypt depth and V/C of Chinese wildrye group were significant different from alfalfa meal group (P<0.05).Jejunum villus height of rice husk meal group and Chinese wildrye group were significantly higher than alfalfa meal group (P<0.05), while crypt depth was significant lower than alfalfa meal group (P<0.05)with no significant differences founding between rice husk meal group and Chinese wildrye group (P>0.05).Muscle thickness of rice husk meal group were significantly higher than alfalfa meal group (P<0.05).Ileac villus height of Chinese wildrye group was significantly higher than the rest groups (P<0.05) and villus width of three groups showed significant differences (P<0.05), rice husk meal group was the biggest.V/C of Chinese wildrye group were significant higher than the other two groups (P<0.05), and muscle thickness of Chinese wildrye group was significantly higher than rice husk meal group and alfalfa group (P<0.05).In conclusion, the different sources of dietary fiber could significantly affect intestinal tissue morphology of adult Yangzhou geese. |
