Evaluating carbohydrate sources for dogs
Brazilian scientist conducted a digestibility study to determine the nutritional value of broken rice, high oil maize, millet, sorghum, maize germ, rice bran and wheat bran as ingredients for dog foods.
Eight adult dogs were housed in metabolic cages, and distributed into 8 × 8 Latin square experimental design, with eight diets and eight replicates per diet.
The difference or substitution method was used to estimate ingredient digestibility.
A reference diet was formulated based on nutritional requirements of dogs. For each test diet, 300 g/kg of the reference diet was replaced with the ingredient evaluated. All the diets were extruded.
Results are shown in the table below.
