Effects of dietary phosphorus and protein in dogs with chronic renal failure.

Finco, D.R. et al.
This study investigates the impact of varying levels of dietary protein (16%, 32%) and phosphorus (P) (0.4%, 1.4%) on 48 dogs with surgically reduced renal mass. After 3 months with a common diet (16% protein, 0.4% P), dogs were distributed in 4 groups with the same mean glomerular filtration rate and received and one of the 4 diets for 24 months. 24 dogs suffered uraemia during the study. 0.4% P diets enhanced dog survival, but protein level had no significant influence on this. The lower amount of P increased the period that glomerular filtration rate remained stable.

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.
