Cooked navy bean powder as novel protein source

Cooked navy bean powder can be safely included as a major food ingredient in canine diet formulations and provide a novel quality protein source
Dry beans (Phaseolus vulgaris L., Fabaceae) are a low-glycemic-index food containing protein, fiber, minerals and essential and bioactive compounds yet have not been evaluated for inclusion in canine commercial diets. The objective of this study was to establish the apparent total tract digestibility and safety of cooked navy bean powder when incorporated into a canine diet formulation at 25% (wt/wt) compared to a macro- and micro-nutrient matched control diet.

Effects of a urolith prevention diet in cats

Feeding a urolith prevention diet increased the urine concentration of glycosaminoglycans.
This study evaluated urine concentrations of glycosaminoglycans, Tamm-Horsfall glycoprotein and nephrocalcin in 10 cats fed a diet formulated to prevent calcium oxalate uroliths. In a previous study, the cats were sequentially fed two diets: the one each cat was consuming prior to urolith detection and a diet formulated to prevent calcium oxalate uroliths.

Home-prepared diets for pets with CKD

Many problems with nutritional adequacy were detected, and use of the recipes could result in highly variable and often inappropriate diets
This study evaluated recipes of 67 home-prepared diets recommended for animals with chronic kidney disease (CKD) to compare the diets’ nutritional profiles to requirements for adult dogs and cats and assess their appropriateness for managing CKD. We analyzed 39 dog food and 28 cat food recipes with computer software to determine calories, macronutrient calorie distribution and micronutrient concentrations.

Avoiding mineral excesses for optimal pet nutrition

Petfood formulations should aim for balanced diets without nutrient excesses, especially with the advancing age of pets in many markets
Many petfood companies stress the importance of meat-first formulations. The implication to consumers is that these diets are better for their pets. However, meat-first diets may result in overages for a number of nutrients, especially protein, fat, calcium and phosphorus.

The formulator’s dilemma: how processing affects pet nutrition

Better understanding of processing influences allows you to turn the art of nutrient fortification into more of a science
Thermal processing—also known as cooking—of petfoods provides a number of benefits, including convenience, enhanced flavor and texture, improved consistency, pathogen control and decreased spoilage. However, extensive processing can increase variability, destroy essential nutrients and create unwholesome by-products. From a formulator’s perspective, this creates a dilemma regarding how to assure the diet is sufficiently fortified while avoiding excess after accounting for processing effects.

Potential benefits of fiber ingredients

Fiber sources can induce different physiological responses in cats, reduce energy digestibility and favor glucose metabolism or improve gut health
The study compared the effects of three fiber sources on the energy and macronutrient digestibility, fermentation product formation, postprandial metabolite responses and colon histology of 24 overweight cats. The cats were fed one of four kibble diets: control (CO, 11.5% dietary fiber); beet pulp (BP, 26% dietary fiber); wheat bran (WB, 24% dietary fiber); or sugarcane fiber (SF, 28% dietary fiber).

Vet cautions pet owners about feeding petfoods with novel ingredients

PetMD vet's blog says pet owners should be careful of feeding petfoods with novel ingredients to pets without a special condition
A recent blog from a veterinarian on PetMD, a pet health website, cautions pet owners about following a new petfood trend of feeding petfoods that contain "novel" ingredients. Dr. Jennifer Coates says petfood manufacturers have started to include "whacky ingredients" in their over-the-counter petfoods, such as buffalo or kangaroo.

Australian plums may extend petfood shelf life

Scientists find two Australian plums with new anti-microbial substances
Australian scientists conducted tests that found new anti-microbial substances in two common native Australian plums that could help prolong the shelf life of petfood, according to a report. Testing done by scientists from Queensland Alliance for Agriculture and Food Innovation and Queensland government revealed that when small amounts of the kakadu and Queensland Davidson plums are combined with organic acids, the plums develop promising new anti-microbial properties.

Sodium selenite: Does this petfood ingredient warrant concern?

After decades of safe use, critics of the petfood industry have planted seeds of doubt and confusion about this essential ingredient
Selenium is an essential trace mineral for dogs and cats. Due to wide variation in selenium content among ingredients used to make petfoods, most manufacturers will include a supplemental source in their trace mineral premix. The predominant form used in petfood is sodium selenite, which has been used for decades without much issue.
