“…Thus, these three parameters presented significant correlation at the starter phase. The increase in IV was observed by several authors who used purified and soluble non-starch polysaccharide added to the diet in experiments with broilers (Jia et al, 2009), pigs (Buraczewska et al, 2007) and fishes (Amirkolaie et ns -not significant; ITT -intestinal transit time (min); IV -intestinal viscosity (Centipoise); EMC -excreta moisture content (%); AME -apparent metabolizable energy (kcal/kg); AMEn -nitrogen-corrected apparent metabolizable energy (kcal/kg); CAM -coefficient of apparent metabolizability (g/g); CAMn -coefficient of nitrogen-corrected apparent metabolizability (g/g); ADC -apparent digestibility coefficient: DM -dry matter (g/g) -CF -crude fat (g/g); CP -crude protein (g/g); OM -organic matter (g/g); A -ash (g/g); Ca -calcium (g/g); P -phosphorus (g/g).…”

-The experiment was carried out to evaluate the effects of continuous ingestion of pectin on intestinal viscosity, intestinal transit time, excreta moisture content, nutrient digestibility and energy metabolism of broilers at starter and growth phases. We used 240 one-day-old Cobb male broiler chicks, distributed in a completely randomized experimental design. Treatments consisted of four concentrations of pectin (0, 10, 30 and 50 g kg -1 ) with six replicates of 10 birds each. The ingestion of pectin supplied in the feed by broilers at the starter phase increased intestinal viscosity and intestinal transit time, reduced excreta moisture, improved the use of apparent metabolizable energy, nitrogen-corrected apparent metabolizable energy, coefficient of apparent metabolizability, coefficient of nitrogen-corrected apparent metabolizability, apparent digestibility coefficient of crude protein and organic matter; worsened calcium utilization and coefficients of apparent digestibility of dry matter; and did not influence the coefficients of apparent digestibility of crude fat, ash and phosphorus. Pectin ingestion during the growth phase increased intestinal viscosity and apparent digestibility coefficients of ash and organic matter, but decreased the dry matter, crude fat, crude protein and calcium. Intestinal transit time, energy metabolism and apparent digestibility coefficient of crude protein showed quadratic behavior according to pectin levels in the feed. Therefore, pectin ingestion by broilers at the starter phase increases intestinal viscosity and intestinal transit time, reduces excreta moisture and improves energy utilization, whereas at the growth phase nutrient digestibility is decreased.

“…However, the impact of dietary fiber on gut morphology is variable and depends on type of fiber, level of inclusion, and digestion site in the GI tract (6,7,19,32). For instance, inulin-type fructan has been shown to promote gut development, and this is suggested to be mediated by the stimulation of LAB in the pig GI tract (32).…”

“…For example, feeding pigs fermentable carbohydrates, including sugar beet pulp pectin, is reported to increase colon microbiota diversity and Lactobacillus amylovorus population (20). Diets with a high content of sugar beet pulp pectin resulted in increased numbers of lactobacilli in the small intestine and short-chain fatty acid (SCFA) products in the colon of weaned piglets (6), whereas apple pectin diets did not affect pig small intestine motility but altered intestinal morphology (7). In addition, a recent study from our group showed that different levels of chicory forage inclusion increased the digestibility of uronic acids and maintained pig performance compared to a cereal-based control diet (17).…”

The content and composition of prebiotic plant fiber in the diet is important in promoting gut-related health. This study investigated the effects of the dietary inclusion of chicory forage and roots on the intestinal microenvironment of pigs. Thirty-sevenweek-old pigs were fed 1 of 5 diets for 18 days, including a cereal-based control diet and 4 diets with the inclusion of 80 and 160 g kg ؊1 of body weight chicory forage (CF80 and CF160), 80 g kg ؊1 chicory root (CR80), and a mix of 80 g kg ؊1 forage and 80 g kg ؊1 chicory root (CFR). The animals maintained good performance and health irrespective of diet. Bacterial community structure and diversity in ileal and colonic samples was assessed using terminal restriction fragment length polymorphism (T-RFLP), combined with cloning and sequencing. Samples clustered perfectly according to gut segment with a higher bacterial diversity in colon than ileum. Distal ileum was dominated by lactic acid bacteria (LAB), and the relative amount of this group was increased by the CF160 and CFR diets. The colonic bacterial community was dominated by butyrate-producing bacteria and Prevotella. The increased relative abundance of butyrate-producing bacteria in the colon was positively correlated with the molar proportion of acetic acid and furthermore linked to the chicory forage diets (CF80 and CF160). Diets including chicory roots (CR80 and CFR) were correlated with a higher colonic abundance of Megasphaera elsdenii. The fermentation products and pH in digesta responded to diet type and were correlated with shifts in the microbiota, showing that chicory influences the intestinal microenvironment of pigs.T he application of 16S rRNA gene-based analyses has revealed a tremendously high diversity of gut microbiota at bacterial species and phylotype levels (22). During the past decade, there has been an intense focus on microbial ecology, with the aim of understanding the links between the gut microbiota, health, and diseases. However, compared to human subjects, limited information is available on the porcine gut, and more than 80% of the bacterial phylotypes identified may represent unknown species (21).Pigs are known to have naturally occurring and economically important enteric diseases, such as swine dysentery and postweaning diarrhea (9, 24). Outbreaks of bacterial diseases in the gut can impose significant constraints on pig production by reducing animal welfare and productivity. The contaminated products can also pose threats to the human food chain (9). To uncover the effect of the gut microbiota upon pig performance and health, the dominant bacterial species that colonize the gut must be identified, and the extent to which these are influenced by diet composition must be determined.Certain substrates, such as dietary fiber, escape digestion in the foregut and reach the hindgut of animals and are now a central issue in nutrition application. These substrates, commonly referred to as prebiotics, can alter gut bacterial composition, modify intestinal fermentation processes, p...

“…A portion of the protein is a component of the NDF matrix and is not free during digestion in the small intestine (Schulze et al, 1994). In addition, NDF and its lignin fraction in particular have a high water retention capacity and thereby increase the viscosity of the digesta, which slows mass transfer and enzymatic reactions, and hence digestion and absorption of nutrients (Buraczewska et al, 2007). Furthermore, gastric, pancreatic and biliary secretions appear to increase with NDF content of the feed (Ikegami et al, 1990), which would increase endogenous losses of protein due to sloughing of intestinal epithelium (Shah et al, 1982) in addition to digestive proteases.…”

Oilseed meal is an important source of essential amino acids (EAA) for livestock production. It is the second most important ingredient in pig feed after grains. Optimal use of these ingredients requires precise knowledge of amino acid standardized ileal digestibility (SID), which may vary depending on several factors including botanical variety or processing treatments. A metaanalysis was performed in order to derive models for predicting the SID of soybean, cotton and rapeseed meal EAA, based on chemical composition data such as CP, total concentration of each EAA and fibre (crude fibre, ADF and NDF) content. A database of 47 references (224 experimental treatments) was built. A model incorporating processing method of the meals (e.g. cold pressed, expeller pressed, solvent extracted), experimental surgical procedure (T-cannula, re-entrant cannula, post valve T-cannula and ileo-rectal anastomosis) and pig growth stage (BW⩽ or ⩾25 kg) was tested. Results indicated that neither processing nor BW affected EAA SID. NDF was the best predictor of SID ( R 2 = 0.944, 0.836, 0.779, 0.899 and 0.814, respectively, for Lys, Met, Thr, Trp and Val). The total EAA content was the best predictor of digestible content (g/kg diet) for each EAA ( R 2 = 0.990, 0.985, 0.977, 0.985 and 0.978, respectively, for Lys, Met, Thr, Trp and Val). This study shows that routine chemical analyses may be used to predict EAA digestibility with satisfactory accuracy.
