Studies the adipose tissue in obese insulin-resistant dogs by researchers from France. Modulation of uncoupling protein 1 (UCP1) and peroxisome proliferator-activated receptor (PPAR) γ expression; Role of PPAR in inflammatory status; Plausibility for UCP1 to contribute to the adaptive change in energy expenditure.

Investigates the relationship between electrolyte apparent absorption and fecal quality in adult dogs differing in body size by researchers from France. Presentation of diversity on body weight and size of the domestic dog among other mammalian species; Evaluation on the potential physiological consequences in relation to the extreme variation; Indications that large-breed dogs have higher fecal water content and greater frequency of soft feces compared with small-breed dogs.

Postprandial hyperglycemia and insulin secretion depend on many factors, such as food composition, carbohydrate type and processing. The purpose of this study was to evaluate the effects of foods differing in composition in nonobese clinically normal dogs. These dogs were offered in a single meal one of the four foods. Blood samples were collected before feeding and during the 180 min after the meal. Plasma glucose and insulin concentrations were determined. The integrated areas under the postprandial glucose and insulin response curves were calculated. Times to response peaks, maximum plasma insulin elevation, area under the insulin response curve and the insulinemic index differed between dog foods. Crude fiber content had no significant effect. The time to glucose peak was higher and the time to insulin peak lower with the food highest in protein and ether extract content. The time to glucose peak was correlated to protein, fat and nitrogen-free extract content of foods, whereas the time to insulin peak and the area under the insulin curve were correlated to protein and nitrogen-free extract.

The article presents a comparative study on insulin sensitivity, insulin secretion, and plasma leptin and insulin-like growth factor-1 (IGF-1) in cats fed diets differing in protein and carbohydrate content. The study utilized normal-weight cats and were assessed with insulin sensitivity and insulin secretion, plasma leptin and IGF-1 level. Findings show that high protein diet do not affect insulin sensitivity or insulin secretion in reaction to glucose in normal-weight cats and present lower IGF-1 level in opposition to results from previous studies. Furthermore, plasma leptin is consistent with the normal weight of the cats. However, further analysis is needed to obtain specific results on the effects of diets on metabolic equilibrium of glucose in cats.

The article presents a study that determines the effect of the two dietary supplements, hydroxycitric acid and conjugated linoleic acid, on body composition, total energy expenditure, and least observed metabolism of adult neutered cats. Normal weight cats, who were fed 50 kilocalorie of a food of metabolizable energy was used in the study. The results show that cats were nonobese and their body weight was stable. It shows that dietary supplements could be more effective in young growing cats.

Examines the effects of high protein intake in nonobese neutered cats by researchers from France. Influence of dietary composition on lean body mass in the cat models; Induction of weight loss with the administration of high-protein diets; Determination on the effect of a limited energy intake of a high-protein diet on the body composition.

Studies on the gastric emptying rate of different dog breeds by researchers from France. Relationship between gastric emptying rate and body weight in different canine body sizes; Tendency for large and giant breeds of dog to defecate more frequently with poor quality of feces when fed with an identical diet to smaller breeds; Efforts of the researchers to gain insight as to the effect of body size on fecal variables in otherwise healthy dogs.
