Raw and Rendered Animal By-Products as Ingredients in dog diets.

Murray, S.M. et al.
This study examined digestion of animal by-products in dog diets, in the ileum and total GI tract. Diets used were extruded kibble containing rendered beef meat and bone meal (RMBM); fresh beef (FB); poultry by-product meal (PBPM); fresh poultry (FP); defatted soy flour (DS) and dehydrated whole egg (WE). Results showed: variations in nutrient intake levels in the ileum and for total tract digestion levels; consistently high amino acid digestibility in the ileum, increased for diets incorporating FP vs PBPM except for cystine with animal by-products greater than DS and lower than WE controls.

A look at how fozen chicken effect digestibility, bioavailability and body weight maintenance. The article illustrate the effects of the Purina proprietary technology on higher protein and fat digestibility, better absorption of essential fatty acid and higher bioavailability of some limiting amino acids such as lysine and arginine thanks to 14-25% of total protein content coming from chicken.

Talk about the importance of doing a complete nutritional evaluation of the patient before instituting a dietary change in any patient, especially an older dog or cat. The patient evaluation, the current diet, and feeding management should be included in this edvaluation. Many diseases in senior pets, as cognitive dysfunction, osteoarthritis, and obesity are “diet-sensitive”, meaning that diet can play a role in managing the effects of the disease.

Pretend to determine whether the chronic ingestion of fermentable dietary fiber regulates the expression and synthesis of proglucagon-derived peptides in the distal intestine. This expression can modulate glucose homeostasis, having positive effects in some special situations.
