Digestibility, which describes the relative amount of nutrients that are available to the body following digestion, is often cited as a measure of a pet food’s quality. The digestibility of dry matter in dog foods should be more than 80 per cent and values for energy, protein, fat and carbohydrate between 80 and 90 per cent. Digestibility is largely determined by the source and quality of ingredients, as well as processing and amount fed. Meat, eggs and dairy products are highly digestible…

Studies on the digestibility of soya bean products, cereals, cereal and plant by‐products in diets of dogs

The apparent digestibility of 21 plant materials was evaluated in dog diets using adult beagles. In most cases the digestibility by difference method was used. Apparent crude protein (N × 6.25)…

Raw and rendered animal by-products as ingredients in dog diets.

Diets fed contained various animal by-products including a rendered beef meat and bone meal; fresh beef (FB); poultry by-product meal (PBPM); fresh poultry (FP); and an animal-based control protein source, dehydrated whole egg (THE AUTHORS).

Effects of fiber on digestibility and transit time in dogs.

Effects of variations in fiber content on nutrient assimilation, fecal output, and gastrointestinal transit time in the dog are examined and regressions of their digestibilities on added fiber were significant.

Influence of dietary protein content and source on fecal quality, electrolyte concentrations, and osmolarity, and digestibility in dogs differing in body size.

Wheat gluten was proved to be a suitable protein source for modulating fecal quality in dogs, particularly in sensitive breeds, and less and overall digestibility was greater for wheat gluten than for poultry meal diets.

Digestibility and compatibility of mixed diets and faecal consistency in different breeds of dog.

Test panels for evaluating commercial diets should include breeds of larger body size and higher sensitivity to dietary disorders, indicating that body weight is not the only factor to be considered when performing tests with dog food.

Dietary fiber for dogs: I. Effects of graded levels of dietary beet pulp on nutrient intake, digestibility, metabolizable energy and digesta mean retention time.

Beet pulp levels up to 7.5% of diet DM appear acceptable as a dietary fiber source in a meat-based canine diet.

Effects of six carbohydrate sources on dog diet digestibility and post-prandial glucose and insulin response.

Variations in diet digestibility and post-prandial response can be explained by differences in chemical composition of each starch source including fibre content and starch granule structure.

Chemical composition, in vitro fermentation characteristics, and in vivo digestibility responses by dogs to select corn fibers.

Nutrient digestibility, food intake, and fecal characteristics were not affected by corn fiber inclusion in canine diets, suggesting that they should be considered as potential dietary fiber sources in dog foods.

Influence of age and body size on the digestibility of a dry expanded diet in dogs.

An effect of age and body size on nutrients digestibility and that the lower faecal quality observed in healthy large breed dogs does not appear related to lower nutrient utilization are shown.

Soybean hulls as a dietary fiber source for dogs.

Results indicate that soybean hulls can be an effective dietary fiber source in dog diets and cause a negative linear effect on calculated ME, in addition to lowering ME when compared with the 0% fiber control diet.
