“…Waldenstedt et al (2000) already showed that coccidial infection decreases intestinal digesta viscosity. It is unclear whether the reduction in viscosity observed in the present study was to be attributed solely to the coccidia or whether C. perfringens also played a role.…”

Stocking density is a management factor which has critical implications for the poultry industry. The aim of the present study was to investigate the effect of high stocking density as a predisposing factor in an experimental model of necrotic enteritis in broiler chicks. The experimental challenge model included an oral inoculation with 10-fold dose of attenuated anticoccidial vaccine and multiple oral inoculations with a specific strain of Clostridium perfringens. Two hundred and forty as hatched day-old broiler chicks were randomly allocated to four treatment groups according to the following experimental design: group N, with normal stocking density (15 birds/m(2)) and no challenge; group D, with high stocking density (30 birds/m(2)) and no challenge; group P, with normal stocking density and positive challenge; and group DP, with high stocking density and positive challenge. From each bird, the intestine, gizzard and liver were collected and scored for gross lesions. The intestinal digesta was collected for pH and viscosity determination. One caecum from each bird was taken for microbiological analysis. The statistical analysis and evaluation of the experimental data revealed significant interaction effects between "stocking density" and "challenge", regarding gross lesion scores in intestine and liver, pH values in jejunum, ileum and caeca as well as C. perfringens counts in the caeca (P ≤ 0.05). High stocking density in challenged birds increased the gross lesion score in the intestine (P ≤ 0.05), contrary to unchallenged birds. It can be concluded that high stocking density affects unfavourably the welfare and gut health of broiler chicks, predisposes to necrotic enteritis in a subclinical experimental model and increases further its importance as a management factor for the poultry industry.

“…Viscosity and fermentability of fibre interacted to modify digesta viscosity. Dietary CMC caused high digesta viscosity in swine (30) and poultry (31) , which was related to the high solubility of CMC (27) . The high in vivo viscosity matched perfectly with the high in vitro viscosity, and thus appeared to confirm the paradigm that a high-viscosity diet results in high digesta viscosity (2) .…”

Effects of viscosity and fermentability of dietary fibre on nutrient digestibility and digesta characteristics in ileal-cannulated grower pigs

et al. 2011

Relative contributions of two functional properties, viscosity and fermentability of dietary fibre, on apparent ileal digestibility (AID), apparent total tract digestibility (ATTD), digesta passage rate, N retention and SCFA concentration have not been established. Thus, eight ileal-cannulated pigs randomised in a double 4 £ 4 Latin square were fed four diets based on maize starch and casein supplemented with 5 % of actual fibre in a 2 £ 2 factorial arrangement: low-fermentable, low-viscous cellulose (CEL); low-fermentable, high-viscous carboxymethylcellulose (CMC); high-fermentable, low-viscous oat b-glucan (LBG); high-fermentable, high-viscous oat b-glucan (HBG). Viscosity and fermentability interacted to affect (P, 0·001) digesta viscosity and AID and ATTD of nutrients. These properties tended to interact to affect (P,0·10) digesta passage rate and butyrate. Pigs fed the CMC diet had the lowest (P,0·05) digesta passage rate and the highest (P,0·001) AID of energy, crude protein and DM, and ATTD of energy and DM. Post-ileal DM digestibility was highest (P,0·001) for pigs fed the CEL and HBG diets. Post-ileal DM digestibility had a negative, curvilinear relationship with the AID of energy and crude protein (R 2 0·85 and 0·72, respectively; P,0·001). Digesta viscosity had a less strong relationship with the AID of energy and crude protein (R 2 0·45 and 0·36, respectively; P,0·001). In conclusion, high-viscous, low-fermentable dietary fibre increases the proportion of a diet that is digested in the small intestine by reducing digesta passage rate.

“…Similarly, digestion may be further reduced with feeds producing highly viscous digesta, with Waldenstedt et al (2000) suggesting that these feeds may increase digestive and health problems thereby decreasing the availability of nutrients.…”

1. Pelleted diets, incorporating whole or ground wheat or barley in the pellets, were fed to broiler chickens and the performance, gastrointestinal development and digesta characteristics of those chickens recorded. 2. Body weight was similar with whole grain incorporation or enzyme application. Food conversion efficiency was improved by addition of enzyme to a full wheat diet. 3. Whole grain inclusion in pellets reduced proventriculus proportional mass and increased gizzard proportional mass with no apparent effects of exogenous feed enzyme addition. 4. Relative ileal mass was reduced by enzyme inclusion in a wheat diet and by inclusion of whole barley in the pellets. 5. Digesta viscosity was increased by whole wheat inclusion but reduced by enzyme inclusion irrespective of grain processing. Inclusion of 200 g/kg of barley did not alter viscosity of digesta beyond the duodenum. 6. Fresh excreta pH was higher with both cereals in the grower phase when whole grain was fed. On the barley diet, this was affected by enzyme addition, which created higher pH from a point earlier in the grower phase than when no enzyme was employed. 7. Evidence of a complex interaction between higher viscosity and pH being involved in differences in ileal relative mass was found through significant relationships being produced by enzyme use on the wheat diet alone.
