Higher Digestibility
-
Apparent total tract nutrient digestibility and metabolizable energy estimation in commercial fresh and extruded dry kibble dog foods (
Shmalberg et al, Nom Nom) -
Apparent total-tract macronutrient digestibility, serum chemistry, urinalysis, and fecal characteristics, metabolites and microbiota of adult dogs fed extruded, mildly cooked, and raw diets (
Alygya et al, Freshpet) -
True nutrient and amino acid digestibility of dog foods made with human-grade ingredients using the precision-fed cecectomized rooster assay (Oba et al, rooster model, JFFD)
Preservation of essential and nonessential nutrients that confer health benefits vs extrusion
-
Effects of extrusion processing on nutrients in dry pet food (
Tran et al) - Roles of plant-based ingredients and phytonutrients in canine nutrition and health (Dr. Shmalberg article which showed that many of the ingredients used in fresh (berries, colorful vegetables, etc) have positive impacts on dog health)
Fresh food appears to create unique changes in the microbiome tied to positive health changes
- Heterogeneity of gut microbial responses in healthy household dogs transitioning from an extruded to a mildly cooked diet (Shmalberg, Nom Nom)
- Effects of a mildly cooked human-grade dog diet on gene expression, skin and coat health measures, and fecal microbiota of healthy adult dogs (Swanson, JFFD)
