“…This structural feature has been also observed by Ferrer et al (1991) in the chicken cecum. The results of microvillus length are in the range of the values obtained in the chicken small intestine by Humprey and Turk (1974), Hodges and Michael (1975) and Smith et al (1990), and the regional differences agree with the results of Ferraris et al (1989) for mammalian species, which show the longest microvilli in middle small intestine.…”

“…The regional comparison of VAF results agrees with the distal reduction previously described for mammalian species (Wood 1944;Pénzes and Skála 1977;Stenling and Helander 1981;Ecknauer et al 1982;Holt et al 1984;Karasov et al 1986;Thomson 1986;Gardner and Steele 1989) and confirms the data of Levin and Mitchell (1984), who have described for the chicken intestine higher values of villus surface in the jejunum than in the ileum. Smith et al (1990) have attributed the smaller development of ileal villus to the lowest luminal concentration of nutrients that reach this intestinal segment.…”

“…At this time there is an abrupt change in the source of nutrients since the yolk sac, a parenteral source of nutrients rich in lipids, is replaced by a carbohydrate-rich solid diet (Buddington and Diamond 1989). Many lines of evidence support that an increase in villus surface area may arise from an increase in food intake (Smith et al 1990) and also from a high-fiber diet (Madara and Trier 1987). In mammals, the transition from milk to a solid diet at weaning is accompanied by an increase in mucosal mass and nutrient absorption capacity (Ferraris 1994).…”

“…The method was applied in the more significant stages of chicken development in relation to nutrient absorption capacity, mainly to monosaccharide and amino acid absorption (Buddington and Diamond 1989;Padrós et al 1993;Rovira et al 1994).The intestinal length is difficult to determine because the intestine is a soft, elastic organ that can present different degrees of contraction. The method employed (Leopold 1953) is a simple, straightforward procedure, which yields accurate and reproducible results, especially when it is used, as in the present case, by the same technician (Freehling and Moore 1987).…”

“…Moreover, Ferraris et al (1989) have demonstrated that the anatomical factors make such a significant contribution in D-glucose transport capacity that they should be considered with a similar importance as the kinetic properties of the transport systems.Our laboratory has been concerned with monosaccharide and amino acid transport in the chicken intestine. These investigations have dealt with the kinetic characterization of the transport mechanisms involved Padrós et al 1993;Rovira et al 1994;Amat et al 1996;Torras-Llort et al 1996) and also with the quantification of the contribution of microvillus surface area to cellular transport capacity Ferrer et al 1991Ferrer et al , 1995. In the present study, a morphometric analysis of the chicken duodenum, jejunum, and ileum during development has been performed taking into account three levels of magnification: macroscopic level (intestinal length and perimeter), light microscopy (villus development), and transmission electron microscopy (microvillus dimensions and density).…”

The mucosal surface area of the chicken duodenum, jejunum, and ileum was determined during development (from 1-day to 12-week-old animals). The morphometric analysis was performed at three magnification levels. The nominal (serosal) surface area was determined at the macroscopic level, from intestinal length and perimeter. Villus and microvillus amplification factors were estimated at light-microscopic and transmission electron-microscopic levels, respectively. The results show, during the period considered: (1) a similar increase in nominal surface area for the three segments (6.5 to 7.2-fold), (2) a rise followed by a slight decrease in the villus amplification factor in the third week of age in the duodenum, a two-fold increase of this variable in the jejunum and no significant developmental variations in the ileum, (3) an increase in the microvillus amplification factor of 1.5-fold in the duodenum and jejunum and of 1.2-fold in the ileum, although a pronounced decrease in the first week of age was observed in the three segments. In conclusion, total mucosal surface area increased, from 1 day to 12 week, 12- to 13-fold in the duodenum and ileum and 20-fold in the jejunum.

Posthatched naive or inoculated male broiler chicks were kept in separate rooms. An inoculum was prepared from intestines of stunting-syndrome affected broiler chicks. Tap water was supplied from 2 L cups, 1 cup per pen. In the Ist experiment, the naive chicks were provided with tap water only and the inoculated ones had free access to tap water or to an electrolyte solution. In the 2nd experiment, the naive and inoculated birds had free access to water in addition to an electrolyte solution. Supplementation was provided up to 3 weeks of age; thereafter all chicks had access to tap water only. Water or electrolyte consumption and body weight (BW) were determined. Total water intake of inoculated chicks was higher than that of naive counterparts (P<0.001). Electrolyte supplementation increased drinking (P<0.001) in inoculated birds more than in naive ones. At 1 week old the weight of the inoculated birds was about 64% of the weight of naive ones; at the age of 4 and 6 weeks it was about 74% and 86% respectively. Compensatory growth was most apparent in the inoculated chicks provided with electrolyte solution. At the age of 6 weeks, the latter exceeded the BW of the exclusively water supplied counterparts by 327 g. Electrolyte supplementation up to the age of 3 weeks had no effect on the naive counterparts. Osmolality was reduced slightly, but very significantly by inoculation; electrolyte supply had no effect on this variable. Sodium concentration in the plasma was higher in the inoculated birds. Plasma albumin was markedly reduced by inoculation on weeks 1 and 2. Whereas the inoculated chicks supplied with electrolytes resumed the level plasma albumin level of the naive chicks on week 3, an over-compensation occurred in the inoculated-water-supplied (IW) group, and they surpassed the naive chicks significantly. Blood hematocrit increased significantly with age; inoculation, age and/or electrolyte supplementation had no effect on this variable. Sodium-dependent glucose transport rates were enhanced in vesicles obtained from inoculated chicks as compared to naive ones. While electrolyte supplementation had no effect on glucose active transport in naive chicks, electrolyte supplementation decreased rates of glucose active transport in inoculated ones. These data demonstrate that electrolyte supplementation during the early age may be used to enhance the tolerance of broiler chicks to stunting-syndrome by improving food and water consumption, and subsequently growth rate during and after cessation of electrolyte supply.
