Abstract:

The objective of this study was to investigate the effect of different sources of fiber on intestinal morphological development of Jilin White geese.Fifty-six geese were fed with diets containing corn straw and Leymus chinensis as the major source of fiber.The height of the villi，depth of the crypts，muscle thickness of the small intestine were measured on d 11，18，25，32，39，46 and 53 by the histological section technique.The results showed that jejunum villus height in geese fed corn straw and Leymus chinensis groups were greater than the other states of intestine.The absolute growth peak of the villus height and muscle thickness from d 11 to 25 were highest in geese fed corn straw and Leymus chinensis groups.The villus height，crypt depth of duodenum and jejunum were significantly higher in geese fed with Leymus chinensis than that in geese fed with corn straw (P＜0.01).Compared to the geese in Leymus chinensis group,those fed with corn straw had higher muscle thickness.The ratio of villus height to crypt depth positively correlated with the increasing age in different intestinal segments in corn straw and Leymus chinensis groups，and the geese in the Leymus chinensis group had higher ratio of villus height to crypt depth than that in corn straw group in the duodenum and jejunum (P＞0.05).The results indicate that，under this experiment condition，intestinal morphological development of Jilin White geese is significantly influenced by different sources of fiber from d 11 to 53，the development of duodenum and jejunum of geese fed with Leymus chinensis is better than those fed with corn straw.
