Abstract Bacillus coagulans GBI-30, 6086 is a commercially available spore-forming non-toxigenic microorganism approved for use in dog foods with high resiliency to stresses associated with commercial manufacturing. The objectives of this research were to examine the effect of Bacillus coagulans on stool quality, nutrient digestibility, and intestinal health markers in healthy adult dogs. Extruded diets containing graded levels of Bacillus coagulans applied either to the base ration before extrusion or to the exterior of the kibble as a topical coating after extrusion were randomly assigned to ten individually housed adult beagle dogs (7 castrated males, 3 spayed females) of similar age (5.75 ± 0.23 years) and body weight (12.3 ± 1.5 kg). The study was designed as 5 x 5 replicated Latin square with 16-d adaptation followed by 5-d total fecal collection for each period. Five dietary treatments were formulated to deliver a dose of 0-, 6-, 7-, 8-, and 9-log10 colony-forming units (CFU) per dog per day for the control (CON), extruded Bacillus coagulans (PEX), and low, moderate, and high Bacillus coagulans coating levels (PCL, PCM, and PCH), respectively. Food-grade TiO2 was added to all diets at a level of 0.4% to serve as an indigestible dietary marker for digestibility calculations. Data were analyzed using a mixed model through SAS (version 9.4, SAS Institute, Inc., Cary, NC) with treatment as a fixed effect and room (i.e., replicate), period, and dog(room) as random effects. Apparent total tract digestibility of organic matter, crude protein, crude fat, and gross energy calculated by the marker method were numerically greatest for dogs fed the 9-log10 dose treatment with increases (P < 0.05) observed in gross energy and organic matter digestibility compared to the negative control. No significant differences were observed in food intake, stool quality, fecal pH, fecal ammonia, fecal short-chain fatty acids, or branched-chain fatty acids for the extruded Bacillus coagulans treatment (PEX) or the coated Bacillus coagulans treatments (PCL, PCM, and PCH) compared to CON. These results suggest that Bacillus coagulans has a favorable impact on nutrient digestibility and no apparent adverse effects when added to extruded diets at a daily intake level of up to 9-log10 CFU in healthy adult dogs.

Abstract Functional pet foods, such as those containing probiotics, are considered a key growth driver in the $37 billion market of dog and cat foods in the United States. Of particular interest to pet food applications is the patented bacterial strain Bacillus coagulans (GBI-30, 6086), a commercially available spore-forming non-toxigenic microorganism with high resiliency to stresses associated with commercial manufacturing. The objectives of this research were to examine the effect of Bacillus coagulans on stool quality, nutrient digestibility, and intestinal health markers in healthy dogs. High-protein, grain-free extruded diets containing graded levels of probiotic applied through extrusion or as a topical coating were fed to ten adult Beagle dogs of similar age. The study was designed as 5 x 5 replicated Latin square with 16-d adaptation followed by 5-d total fecal collection for each period. The five dietary treatments were formulated to deliver a dose of 0-, 6-, 7-, 8-, and 9-log10 colony-forming units (CFU) per dog per day. Data were analyzed using a mixed model through SAS (version 9.3, SAS Institute, Inc., Cary, NC) with treatment and period as fixed effects and dog as random effect. Apparent digestibility of organic matter, crude protein, crude fat, and gross energy were greatest for dogs fed the 9-log10 dose treatment (85.8, 83.6, 91.7, 84.0%, respectively), with increases (P < 0.05) observed in gross energy and organic matter digestibility compared to the negative control. Crude protein digestibility tended (P < 0.10) to increase as probiotic dose increased. No significant differences were observed in food intake, stool quality, fecal pH, fecal ammonia, or fecal short chain fatty acids. These results suggest that Bacillus coagulans has a favorable impact on nutrient digestibility and no apparent adverse effects when added to extruded diets at a daily intake level of up to 9-log10 CFU in healthy adult dogs.

This study evaluated the potential of monoglyceride blend (MG) and buffered formic acid (FA) as alternatives to antibiotics in the performance and intestinal health of broilers under clinical necrotic enteritis (NE) challenge. A total of 544 as-hatched Ross 308 broiler chicks were randomly distributed to 32-floor pens housing 17 birds per pen. The four treatments were: NC—non-additive control; ZBS—antibiotic group supplemented with zinc bacitracin and salinomycin; MG—additive MG supplementation in the starter phase only; and MGFA—additive MG in starter phase and FA in grower and finisher phases. All birds were challenged with Eimeria spp. and Clostridium perfringens. Results showed that the NC group had lower BWG and higher FCR than the ZBS group in the grower and overall period (p < 0.05). The NC group had higher NE-caused mortality (days 14 to 17) than the ZBS group (p < 0.05). Birds fed MG had lower NE-caused mortality than the NC group (p < 0.05). Birds fed MG had upregulated jejunal tight junction protein1 (TJP1) and immunoglobulin (IgG) on day 16 and improved gross energy digestibility on day 24 than the NC group (p < 0.05). These findings suggest that supplementation of MG may improve intestinal health and protect birds from clinical NE occurrence.

Abstract In theory, supplementing xylanase in corn-based swine diets should improve nutrient and energy digestibility and fiber fermentability, but its efficacy is inconsistent. The experimental objective was to investigate the impact of xylanase on energy and nutrient digestibility, digesta viscosity, and fermentation when pigs are fed a diet high in insoluble fiber (&gt;20% neutral detergent fiber; NDF) and given a 46-d dietary adaptation period. Three replicates of 20 growing gilts were blocked by initial body weight, individually housed, and assigned to 1 of 4 dietary treatments: a low-fiber control (LF) with 7.5% NDF, a 30% corn bran high-fiber control (HF; 21.9% NDF), HF+100 mg xylanase/kg [HF+XY, (Econase XT 25P; AB Vista, Marlborough, UK)] providing 16,000 birch xylan units/kg; and HF+50 mg arabinoxylan-oligosaccharide (AXOS) product/kg [HF+AX, (XOS 35A; Shandong Longlive Biotechnology, Shandong, China)] providing AXOS with 3-7 degrees of polymerization. Gilts were allowed ad libitum access to fed for 36-d. On d 36, pigs were housed in metabolism crates for a 10-d period, limit fed, and feces were collected. On d 46, pigs were euthanized and ileal, cecal, and colonic digesta were collected. Data were analyzed as a linear mixed model with block and replication as random effects, and treatment as a fixed effect. Compared with LF, HF reduced the apparent ileal digestibility (AID), apparent cecal digestibility (ACED), apparent colonic digestibility (ACOD), and apparent total tract digestibility (ATTD) of dry matter (DM), gross energy (GE), crude protein (CP), acid detergent fiber (ADF), NDF, and hemicellulose (P&lt;0.01). Relative to HF, HF+XY improved the AID of GE, CP, and NDF (P&lt;0.05), and improved the ACED, ACOD, and ATTD of DM, GE, CP, NDF, ADF, and hemicellulose (P&lt;0.05). Among treatments, pigs fed HF had increased hindgut DM disappearance (P=0.031). Relative to HF, HF+XY improved cecal disappearance of DM (162 vs. 98g; P=0.008) and NDF (44 vs. 13g; P&lt;0.01). Pigs fed xylanase had a greater proportion of acetate in cecal digesta and butyrate in colonic digesta among treatments (P&lt;0.05). Compared with LF, HF increased ileal, cecal, and colonic viscosity, but HF+XY decreased ileal viscosity compared with HF (P&lt;0.001). In conclusion, increased insoluble corn-based fiber decreases digestibility, reduces cecal fermentation, and increases digesta viscosity, but supplementing xylanase partially mitigated that effect.

A solution of ammonium salts of a mixture of short-chain fatty acids (mainly acetic acid) was added to the sole source of drinking water of 10 lactating Jersey cows. There was considerable variation in the concentration of salts tolerated without depression in water intake. Some animals refused solution offered at a concentration of 0·5% (w/w) whereas one animal accepted solution at a concentration of 8% (w/w) and had a mean daily intake of salts equivalent to 836 g acetic acid.2. Adjustment of the pH of the drinking solution to 6·5–7·5 increased the tolerance to the salts solution of animals which showed a low tolerance to the unadjusted solution. A mean daily intake equivalent to 480 g acetic acid was achieved without a significant depression of water intake. Replacement of 50 % of the ammonium ions by calcium increased the intake of salts by some cows but two out of eight refused the solution at a concentration of 0·5% (w/w).3. The addition of saccharine, vanilla or aniseed to a solution of the ammonium salts gave little or no improvement in acetate intake but sodium cyclamate, ethyl acetate or molasses reduced the variability between animals in their tolerance to the solution and increased the mean intake of salts. With an addition of molasses, which gave the most marked response, there was a mean daily intake of salts equivalent to 495±26 g acetic acid.

Abstract This study aimed to evaluate the effect of Bacillus coagulans GBI-30, 6086 on the fecal microbiome of healthy adult dogs. Extruded diets containing graded levels of probiotic applied either to the base ration before extrusion or as a topical coating post-extrusion were randomly assigned to ten individually-housed Beagle dogs (7 castrated males, 3 spayed females) of similar age (5.75 ± 0.23 yr) and body weight (12.3 ± 1.5 kg) in a 5 x 5 replicated Latin square with 16-d adaptation and 5-d total fecal collection for each period. Five dietary treatments were formulated to deliver a dose of 0-, 6-, 7-, 8-, or 9-log10 CFU·dog-1·d-1. Fresh fecal samples (n=50) were analyzed by 16S rRNA gene pyrosequencing. Community diversity was evaluated in R (v4.0.3, R Core Team, 2019). Relative abundance data were analyzed using a mixed model (v9.4, SAS Institute, Inc., Cary, NC) with treatment and period as fixed effects and dog as a random effect. Results were considered significant at P &lt; 0.05. Predominant phyla were Firmicutes (mean 81.2% ± 5), Actinobacteria (mean 9.9% ± 4.4), Bacteroidetes (mean 4.5% ± 1.7), Proteobacteria (mean 1.3% ± 0.7), and Fusobacteria (mean 1.1% ± 0.6). No evidence of shifts in predominant phyla, class, family, or genus taxonomic levels were observed except for the Bacillus genus, which had a greater relative abundance (P = 0.0189) in the low probiotic coating and high probiotic coating treatment groups compared to the extruded probiotic group. Alpha-diversity indices (Richness, Chao1, ACE, Shannon, Simpson, Inverse Simpson, and Fisher) and beta-diversity metrics (principal coordinate analysis and multi-dimensional scaling) were similar for all treatments. This data indicates that supplementation with Bacillus coagulans GBI-30, 6086 at a dose of up to 9 log10 CFU·d-1 did not alter the overall diversity of the fecal microbiome of healthy adult dogs over a 21-d period.

Dietary fibre (DF) and fermentable crude protein (fCP) are dietary factors which affect nutrient utilization and intestinal health in pigs. A nitrogen (N)-balance study was conducted to determine the impact of DF and fCP on threonine (Thr) requirement for protein deposition (PD) and indicators of intestinal health. A total of 160 growing pigs (25 kg) were randomly assigned to 1 of 20 dietary treatments in a 2 × 2 × 5 factorial arrangement in a randomized complete block design with dietary fibre (low (LF) or high fibre (HF)], fCP [low (LfCP) or high fCP (HfCP)) and Thr (0.52, 0.60, 0.68, 0.76, or 0.82% standardized ileal digestible) as factors. Then, 4-day total urine and fecal collection was conducted, and pigs were euthanized for intestinal tissue and digesta sampling. Feeding high DF, regardless of fCP content, increased Thr requirement for PD (p < 0.05). High fCP, regardless of DF content, reduced Thr requirement for PD. Serum antioxidant capacity increased as dietary Thr level increased (p < 0.05). Cecal digesta short-chain fatty acids (SCFA) increased (p < 0.05) with HF and branched-chain fatty acids (BCFA) increased with HfCP and reduced with HF (p < 0.05). HfCP reduced (p < 0.05) mucin-2 (MUC2) expression in the colon of the HF but not the LF fed pigs and HF increased MUC2 in the LfCP but not the HfCP fed pigs. Feeding HF diet increased (p < 0.05) expression of zonula occludens-1 in the LfCP with no effect on HfCP fed pigs. Ammonia concentration in both cecum and colon increased (p < 0.05) in the HfCP fed pigs. Overall, high DF reduced the negative impact of HfCP on intestinal health, as indicated by alterations in SCFA and BCFA production and gut barrier gene expression. While increased dietary Thr content is required for PD in pigs fed high DF, feeding high fCP reduced Thr requirements.

Pentose Sugars

Hemicellulose consists primarily of pentose sugars, joined together in a polysaccharide chain with d-xylose as the most abundant component. Ileal digestibility and urinary excretion of d-xylose and associated effects of this pentose sugar on ileal and faecal digestibility of dry matter (DM), organic matter (OM), gross energy (GE) and nitrogen were studied in pigs. Castrated pigs were prepared with a post-valvular T-caecum cannula to measure ileal digestibility. Faecal digestibility was measured in non-cannulated pigs. d-xylose was given at dietary inclusion levels of 100 and 200 g/kg, and the control sugar, d-glucose, at a rate of 200 g/kg diet. Ileal digestibility of d-xylose as well as that of d-glucose was found to be close to 100%. The presence of d-xylose in the diet decreased ileal digesta pH and increased ileal flow of volatile fatty acids, suggesting the occurrence of microbial degradation of d-xylose in the pig small intestine. In pigs fed on the 100 g d-xylose/kg diet, 44.5% of the d-xylose intake appeared in the urine. This percentage increased significantly to 52.6 when pigs were fed on the 200 g d-xylose/kg diet. Ileal and faecal digestibility of DM, OM, GE and N, as well as N retention, decreased significantly in pigs fed on the 200 g d-xylose/kg diet.

Objectives The aim of the study was to evaluate overall dry matter, organic matter, crude protein, crude fat and gross energy digestibility of a feline commercial raw diet and a homemade raw diet compared with a canned, heat-processed diet. Methods Six domestic shorthair kittens (20–28 weeks old) were fed three different diets in a Latin square crossover design. Diet A was a commercially available, canned, heat-processed diet. Diet B was a complete commercial, prefrozen, raw diet (commercial raw), and diet C was a raw diet supplement mixed with ground raw meat obtained locally (homemade raw). Both diets A and B were formulated to meet nutritional profile levels for cats at all life stages. Kittens were given specific diet amounts to maintain a 2–4% weight increase per week. Food was measured before and after feedings to determine the amount eaten, and all feces were collected, weighed and frozen prior to submission. Composite food samples and all feces were submitted to a national laboratory for proximate analysis of crude protein, crude fiber, ash, crude fat, moisture and caloric density. Results Significantly higher digestibility of dry matter ( P <0.001), organic matter ( P <0.001), crude protein ( P <0.001) and gross energy ( P <0.001) was seen in the raw diets compared with the heat-processed diets. This difference resulted in significantly less fecal matter ( P <0.001) despite similar levels of intake and kcal ingested, and evidence of no difference in fecal scores. Conclusions and relevance Higher dry matter, organic matter and protein digestibility was seen in two commercial raw diets compared with a heat-processed diet. Digestibility differences could have been due to variance in dietary protein, fat and carbohydrate concentrations between the diets, variance in dietary ingredients or quality, alterations in protein structure secondary to heat processing, as well as alterations in gastrointestinal flora. Future research examining digestibility in diets with the same macronutrient proportions and ingredients, and mechanisms for any differences, is warranted.

Quantitative studies have been made of digestion in the small and large intestines of sheep offered a diet of subterranean clover (Trifolium subterraneurn c.v. Clare) at levels approaching ad libitum. As in previous studies with a similar diet, most of the digestion of organic matter and of cell wall constituents occurred in the stomach; by contrast, the release of long-chain fatty acids and amino acids mainly occurred in the intestines. Although two-thirds of the dietary long-chain fatty acids were C18:2 and C 18: 3, hydrogenation in the rumen reduced their proportion to less than 20 % in the digesta leaving the stomach. The amounts of long-chain fatty acids that passed from the stomach were equivalent to about 127 % of intake. Approximately 70 % of these fatty acids were removed from the digestive tract subsequently, and most of the absorption occurred in the small intestine. The total amounts of these fatty acids absorbed from the intestines were equivalent to approximately 90% of the amount consumed, even though their apparent digestibility in the whole tract was only 61 %. Most of the nitrogen that passed from the stomach was in the form of amino acids. Of the 189 g amino acids that passed from the stomach, less than one-third reached the terminal ileum. The net losses of individual amino acids in the small intestine ranged from 66% to 84% of the amounts that passed from the stomach. It was estimated that approximately one-third of the organic matter and almost 60% of the nitrogen that passed from the stomach was present in bacterial cells. A major component of bacterial cell walls, diaminopimelic acid, was apparently not absorbed from the small intestine, though appreciable amounts of this amino acid were lost in the large intestine.

Intestines are not only major organs for nutrient digestion and absorption, but are also the largest immune organ in pigs. They are essential for maintaining the health and growth of piglets. Fatty acids, including short-chain fatty acids, medium-chain fatty acids, and long-chain polyunsaturated fatty acids, are important nutrients; they are a major energy source, important components of the cell membrane, metabolic substrates in many biochemical pathways, cell-signaling molecules, and play role as immune modulators. Research has shown that fatty acids exert beneficial effects on intestinal health in animal models and clinical trials. The objective of this review is to give a clear understanding of the regulatory effects of fatty acids of different chain lengths on intestinal health in pigs and their signaling pathways, providing scientific reference for developing a feeding technique to apply fatty acids to piglet diets.
