“…Our current histological findings show that duodenal and ileal villus height were decreased (P<0.05) in the low-CP group, and duodenal villus area tended to be decreased (P<0.05) in both the low-CP and low-EE groups, while the ileum showed a lower value (P<0.05) in only the low-CP group. Similarly, previous reports in chickens refed unbalanced nutrient compositions have demonstrated that intestinal villi were shorter and narrower than Incharoen et al in chickens refed a nutritionally well-balanced diet (Maneewan and Yamauchi, 2003, 2004. Decreasing values for villus characteristics corresponded with reductions in the villus surface area, enzyme activities such as mucosal lactase and sucrease (Park et al, 1998), lactase and alkaline phosphatase (Zijlstra et al, 1997), total lactase phlorizin hydrolase and mucosal protein concentration (Dudley et al, 1998), and alkaline phosphatase and disacchar idase (López-Pedrosa et al, 1998).…”

To establish the intestinal histological alterations in chickens fed low-crude protein (CP) or low-crude fat (EE) in long-term isocaloric diets, 60 birds were allotted to three treatments, each with five replicates of four chickens. They were fed the control, low-CP or low-EE diet from the age of 9 to 16 weeks. The chickens receiving the low-CP diet showed a clear reduction in performance and carcass characteristics like breast and wings. However, these adverse effects did not occur in the chickens fed the low-EE diet. The villus height in the duodenum and ileum were lower (P<0.05) in the low-CP group. The duodenal villus area decreased (P<0.05) in both the low-CP and low-EE groups, whereas the ileum showed a lower value (P<0.05) in only the low-CP group. The cell area of the duodenum and jejunum displayed decreasing values (P<0.05) in the low-CP and low-EE groups. As regards the mitotic numbers, the jejunum and ileum showed a decrease (P<0.05) in the low-CP group. On the villus tip surface in the duodenum of the control and low-EE groups, clear protuberant cells and cell clusters with a great number of epithelial cells were found. These cell clusters degraded to faintly dome-shaped cells in the low-CP group, resulting in a lower level of morphological changes than in the other two groups. The epithelial cells on the jejunal and ileal tip surfaces did not show a specific change in the treatment groups.

“…The values of the light microscopic parameters tended to recover to the control level after 1 day of refeeding with formula mash and pellet diets but did not recover in the semi‐purified pellet diet group (Maneewan & Yamauchi 2003). However, various sizes of cell clusters and deeper cells at the sites of recently exfoliated cells were observed on the villus tip in addition to dome‐shaped cells in the formula mash and pellet diet groups.…”

The general histological features of the small intestine are well known. However, histological intestinal alterations induced by ingested feeds have not been established. To demonstrate such a relationship; (i) the post‐hatching development of intestinal villi in chickens was observed; (ii) histological intestinal differences were compared in White Leghorns and broilers; and (iii) histological intestinal alteration was investigated in fasting and refeeding treatments, using chickens and piglets. Histological intestinal recovery responses; (iv) to luminal nutrient absorption, intraluminal physical stimulation, or intravenous parenteral alimentation in fasted chickens, as well as; (v) to particle size and nutritional level of refed diets in fasted chickens and piglets were also compared. To induce compensatory enlargement of ileal villi; (vi) the jejunum was surgically resected. To reconfirm the histological intestinal alterations induced artificially; (vii) conventional feeding experiments were enforced in chickens and piglets. These fundamental investigations demonstrate that the high values of villus height, cell area and cell mitosis numbers as well as protuberated epithelial cells are hypertrophied by ingested feeds. Finally, as examples of practical use in the animal production field; (viii) useful feed resources to improve the growth performance by activating the intestinal function in chickens and piglets; and (ix) an effective forced molting method are introduced. Based on the histological intestinal alterations related with growth performance in chickens and piglets, this article reviews progress in the establishment of a histological intestinal index to assess the intestinal function.

“…Further study is being carried out to find such a component from SCE. Besides, small particle feed ingredient such as semi-purified pellet diet can easily induce hypertrophic intestinal alteration at epithelial level than villus level (Maneewan and Yamauchi, 2003).…”

Effects of sugar cane extract (SCE) on the piglet intestinal histology were observed. Twelve castrated male piglets weaned at the age of 26 days were allotted to three groups fed diets containing 0, 0.05 or 0.10% SCE. At the end of feeding experiment, each intestinal segment was taken for light or scanning electron microscopy. Feed intake, body weight gain and feed efficiency did not show a difference among groups. Most of the values for villus height, villus area, cell area and cell mitosis numbers were not different among groups, except for that the villus area of the 0.10% SCE group and the cell area of both SCE groups increased significantly at the jejunum compared to the control (P<0.05). For cell mitosis numbers, the 0.10% SCE group was higher than the 0.05% SCE group at the jejunum. Compared with the majority of flat cells of each intestinal segment in the control, the SCE groups had protuberated cells. In the 0.05% SCE group, deeper cells at the sites of recently exfoliated cells in the duodenum, cell clusters aggregated by protuberated cells in the jejunum and much more protuberant cells in the ileum were observed. These histological intestinal alterations suggest that SCE could raise the functions of intestinal villi and epithelial cells, especially at the 0.05%.
