“…Fasting treatment induced a decrease of duodenal villus height (Yamauchi et al . 1995, 1996; Shamoto et al . 1999; Shamoto & Yamauchi 2000; Tarachai & Yamauchi 2000; Yamauchi & Tarachai 2000).…”

“…These villi sizes were increased by activated cell mitosis as well as by decreased cell loss from the villus tip. In addition, the morphology of epithelial cells distributed over the duodenal villus apical surface was affected by fasting (Shamoto et al . 1999; Shamoto & Yamauchi 2000; Tarachai & Yamauchi 2000).…”

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.

“…Histological changes in the intestines have been proposed to be related to intestinal functions (Shamoto and Yamauchi, 2000;Yamauchi and Tarachai, 2000) and may be stimulated by diet (Yamauchi et al, 1996;Shamoto et al, 1999). Furthermore, the reduced thickness of the intestinal walls as a result of feed additives or nutritional manipulations facilitates the digestion of nutrients, which positively affects the growth performance of the animals (Dibner et al, 1996;Jamroz et al, 2006).…”

The gut health of poultry is closely associated with feeds and feeding. The experiment was conducted to the effect of crude glycerol addition to diets of male broilers on the bacterial microflora and morphology of their small intestines (duodenum, jejunum and ileum). A total of 120 Ross 308 broiler chicks received diets containing 0% (GLY 0), 4% (GLY 4) or 8% (GLY 8) crude glycerol for 42 days. The presence of Coliform bacteria and Enterobacteria was reduced in the duodenal tract of the broilers of GLY 4 (P < 0.001); however, the presence of Staphylococci/Micrococci in the GLY 8 was reduced relative to the other groups (P < 0.001). The presence of Salmonella spp. decreased in conjunction with the increasing quantities of glycerol (P < 0.001). Analysis of the data regarding gut morphology (epithelial cell thickness, villi length and width, and crypt length and width) indicated that the glycerol levels fed to the different groups of broilers represented statistically different results in the small intestine. In general, whereas the diet with 4% glycerol statistically affected the investigated parameters of the gut, the diet with 8% glycerol statistically affected some segments of the broiler intestines.Keywords: glycerol, broilers, bacterial microflora, villi, crypt ImplicationsAlthough glycerol can be an attractive alternative energy source for animal feed, it has its own limitations in terms of lower energy content than oils, impurities and possible effects on the metabolic activity of the animals. There are still a number of unanswered questions about glycerol. One of the questions is what is the effect of glycerol on gut health? We wanted to investigate the potential physiological effects of glycerol on the intestine of broilers. This research was aimed at determining the effects of crude glycerol levels on the bacterial microflora and morphology of the small intestines in male broilers.

“…Thus, the changes in GOSS amounts did not have negative or positive effect on epithelial cells. It was declared that the histological changes in the intestine were stimulated by diet (Langhout et al., 1999; Yasar and Forbes, 1999), and nutrition manipulations were closely related to intestinal functions (Shamoto et al., 1999; Yamauchi and Tarachai, 2000). Villus height, villus width and epithelial cells on villus can change due to diet and can be helpful signs for evaluating the absorption of the diet content and feed additives in the intestine.…”

“…It is known that the histological changes in the intestine are closely related to intestinal functions (Shamoto et al., 1999; Yamauchi and Tarachai, 2000) and a fine absorption is related to intestinal functions (Langhout et al., 1999; Yasar and Forbes, 1999). It is expressed that the thinning of intestinal wall, due to the manipulation of some of feed or feed additives, for providing nutrients to be absorbed more easily has a positive effect on growth performance of animals (Dibner et al., 1996; Jamroz et al., 2006).…”

Summary In the present study, the effect of varied gossypol (GOSS) amounts was investigated on blood parameters, the digesta pH, villus height, villus width, and crypta depth, width of duodenum, jejunum and ileum. A total of one hundred eight Ross 308 male broilers were fed with four diet groups as follows: no gossypol (control), gossypol rate 62 mg/kg (GOSS 62), gossypol rate 124 mg/kg (GOSS 124) and gossypol rate 186 mg/kg (GOSS 186). The effect of used gossypol amounts on blood parameters was not found to be statistically significant. Increases in digesta pH values of jejunum and ileum with GOSS 186 diet group were found to be statistically significant. The results also indicated that, except duodenum villus height, there was no statistical difference effect of GOSS on epithelial cell thickness, villus height, villus width, crypta depth and crypta width of the duodenum, jejunum and ileum. There have been no clearly negative effects of higher gossypol amounts up to 186 mg/kg diets on these parameters.
