Abstract

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.
