The natural diet of felids contains highly digestible animal tissues but also fractions resistant to small intestinal digestion, which enter the large intestine where they may be fermented by the resident microbial population. Little information exists on the microbial degradability of animal tissues in the large intestine of felids consuming a natural diet. This study aimed to rank animal substrates in their microbial degradability by means of an in vitro study using captive cheetahs fed a… Expand
The effects of a wool hydrolysate on short-chain fatty acid production and fecal microbial composition in the domestic cat (Felis catus).
TLDR
Findings indicate that wool hydrolysates offer promise as an animal-derived supplement source for pet diets, being similar to currently used dietary fiber supplements. Expand
In vitro influence of dietary protein and fructooligosaccharides on metabolism of canine fecal microbiota
TLDR
Results from the present study showed that diets rich in protein may exert negative influences on the canine intestinal ecosystem, slightly increasing the presence of ammonia and reducing counts of lactobacilli and enterococci and administration of FOS may improve metabolism of canine intestinal microbiota. Expand
Are carnivore digestive separation mechanisms revealed on structure-rich diets?: Faecal inconsistency in dogs (Canis familiaris) fed day old chicks
TLDR
Although the structure difference between diets did not affect the faecal dichotomy, feeding whole prey provoked the occurrence of the latter which raises suspicion of a digestive separation mechanism in the canine digestive tract. Expand
Faecal microbiota of domestic cats fed raw whole chicks v. an extruded chicken-based diet*
TLDR
Shifts in faecal bacterial populations compared with feeding a whole-prey diet may impact the functional capacities of the microbiota and its interaction with the host. Expand
Effect of feeding Jerusalem artichoke (Helianthus tuberosus) root as prebiotic on nutrient utilization, fecal characteristics and serum metabolite profile of captive Indian leopard (Panthera pardus fusca) fed a meat-on-bone diet.
TLDR
Results of this experiment showed that feeding JA at 2% DM in the whole diet could be potentially beneficial for captive Indian leopards fed meat-on-bone diets. Expand
Fermentability of select polyphenol-rich substrates in the canine faecal inoculum and their interaction with a canine-origin probiotic: an in vitro appraisal.
TLDR
Overall, the results indicate a higher hindgut fermentability of JAT, ORP, and IBP, suggesting their potential beneficial effects for gut health application. Expand
Phylogenetic analysis of faecal microbiota from captive cheetahs reveals underrepresentation of Bacteroidetes and Bifidobacteriaceae
TLDR
The role of the domestic cat is questioned as the best available model for nutritional intervention studies in endangered exotic felids because of marked underrepresentation of Firmicutes in the faecal microbiota. Expand
A diet change from dry food to beef induces reversible changes on the faecal microbiota in healthy, adult client-owned dogs
TLDR
Evaluating how a diet change from commercial dry food to one with a high content of boiled minced beef and vice versa influenced the faecal microbiota, and short chain fatty acid profile in healthy, adult, client-owned dogs can aid in the understanding of how diet changes influence the faECal microbiota and metabolite content on a short-term basis. Expand
Impact of diets with a high content of greaves-meal protein or carbohydrates on faecal characteristics, volatile fatty acids and faecal calprotectin concentrations in healthy dogs
TLDR
The HPGM diet led to diarrhoea in all dogs, and there were differences in faecal VFA profiles andFaecal canine calprotectin concentrations. Expand
Rabbit Carcasses for Use in Feline Diets: Amino Acid Concentrations in Fresh and Frozen Carcasses With and Without Gastrointestinal Tracts
TLDR
None of the rabbit samples met any recommendation for taurine concentrations for commercial canned or dry extruded diets, ranging from 20 to 90% of the minimum values, and Taurine supplementation is recommended when feeding rabbit to cats. Expand

Animal fibre: the forgotten nutrient in strict carnivores? First insights in the cheetah.
TLDR
The divergent SCFA ratios and the decrease in putrefaction when fed whole rabbit could be caused by the presence of undigested tissue, such as skin, bone and cartilage, that might have fibre-like functions. Expand
Feline colonic microbes and fatty acid transport: Effects of feeding cellulose, beet pulp and pectin/gum arabic fibers
TLDR
It is concluded that if fiber is to be included in the diet of the domestic cat, a moderately fermentable fiber (e.g., beet pulp) would be the dietary fiber of choice. Expand
An in vitro batch culture method to assess potential fermentability of feed ingredients for monogastric diets
TLDR
An in vitro method to assess feed ingredients, as potential components of monogastric diets, which stimulate a positive fermentation and which will be well fermented and produce more short-chain fatty acids (SCFA) and less ammonia is described. Expand
Dietary fiber for cats: in vitro fermentation of selected fiber sources by cat fecal inoculum and in vivo utilization of diets containing selected fiber sources and their blends.
TLDR
The SC diet, which contained the most fermentable fibers, severely decreased nutrient digestibility and resulted in poor stool characteristics, and diets that contain moderately fermentable fiber provide fermentation end products that may be important in maintaining the health of the gastrointestinal tract of the cat. Expand
In vitro fermentation of selected fibrous substrates by dog and cat fecal inoculum: influence of diet composition on substrate organic matter disappearance and short-chain fatty acid production.
TLDR
In vitro substrate OMD increased and A:P decreased when fecal inoculum from dogs and cats fed diets containing a supplemental source of fermentable fiber was used, and in vitro fermentation of fibrous substrates by fecal microflora from Dogs and cats increased with inclusion of fermentables fiber in the diet. Expand
Comparative in vitro fermentation activity in the canine distal gastrointestinal tract and fermentation kinetics of fiber sources.
TLDR
Results of this study can be used to formulate canine diets that stimulate dietary fiber fermentation along the distal GIT that may optimize GIT health and stimulate the level of satiety in dogs. Expand
Fermentation in the large intestine of single-stomached animals and its relationship to animal health
TLDR
The present review examines the micro-ecology of the GIT, with most emphasis on the large intestine as the most important site of fermentative activity, and an attempt is made to clarify the importance of the microfloral activity (i.e. fermentation) in relation to the health of the host. Expand
Differences in microbial activity of digesta from three sections of the porcine large intestine according to in vitro fermentation of carbohydrate-rich substrates
TLDR
It was concluded that, while faecal sampling might overestimate caecal fermentation, its use is valid for in vitro assessment of large intestinal fermentation, however, differences between pigs indicate that a mix of samples from several animals remains important. Expand
Adaptation of healthy adult cats to select dietary fibers in vivo affects gas and short-chain fatty acid production from fiber fermentation in vitro.
TLDR
Overall, adaptation to either FOS or pectin led to greater SCFA and gas production, but adaptation to FOS resulted in the greatest effect overall. Expand
Dietary protein concentration affects intestinal microbiota of adult cats: a study using DGGE and qPCR to evaluate differences in microbial populations in the feline gastrointestinal tract.
TLDR
In this experiment, a high-protein diet resulted in a dramatic shift in microbial populations of adult cats fed diets containing different protein concentrations, which may justify prebiotic supplementation for such diets. Expand
