Effects of <i>Bacillus coagulans</i> (GBI-30, 6086) supplementation on apparent total tract nutrient digestibility and the fecal characteristics and metabolites, immunity, and microbiota of healthy adult dogs
Bibliographic record
Abstract
Bacillus coagulans GBI-30, 6086, is a lactic acid-producing, spore-forming bacteria with diverse characteristics that lend it resiliency through commercial pet food processing, storage, and chemical and enzymatic digestion through the gastrointestinal tract. The objective of this study was to determine the effects of B. coagulans on dietary apparent total tract nutrient digestibility (ATTD) and the hematology, immunoglobulin concentrations and fecal characteristics, metabolites, and microbiota populations of healthy adult dogs. Adult English Pointer dogs (n = 12; age = 5.9 ± 2.5 yr; body weight = 26.6 ± 6.1 kg) were fed the same diet but supplemented with B. coagulans or a placebo via gelatin capsules in a replicated 3 × 3 Latin square design. Capsules were administered daily before each feeding, with the following treatments tested: (1) basal diet + placebo (control; 250 mg maltodextrin); (2) basal diet + B. coagulans [low dose; 5 × 108 colony-forming units (CFU)/d]; and (3) basal diet + B. coagulans (high dose; 2.5 × 109 CFU/d). Fecal, blood, nasal, and pinnae samples were collected after a 22-d adaptation phase in each period. Data were analyzed using the Mixed Models procedure of SAS 9.4, with P < 0.05 being significant and P < 0.10 being trends. Bacillus coagulans supplementation did not affect ATTD, food intake, fecal metabolites, immunoglobulin concentrations, or hematology, but did lower fecal scores (P < 0.05; firmer stool). Using qPCR, fecal Faecalibacterium spp. abundance was greater (P < 0.05) and fecal Bacteroides spp., Bifidobacterium spp., and Ruminococcus gnavus abundances tended to be greater (P < 0.10) in dogs fed the low B. coagulans dose than those fed the placebo. Overall, our results demonstrate that this bacterial species can be safely supplemented to healthy dogs without a negative impact on nutrient digestibility or canine health parameters, and supplementation with the low dose treatment may help maintain fecal consistency and positively influence gastrointestinal microbiota.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
