Even if a pet food is formulated to provide all of the essential nutrients required by a dog, it is of little value if the animal will not eat it. Quality pet foods are carefully formulated not only to be highly nutritious but also to be highly palatable.
Palatability is a term used to describe how well a dog likes the taste, smell, and texture of a food. A premium dog-food manufacturer spends a considerable amount of time conducting controlled feeding studies to determine the right combination of ingredients and processing techniques to produce a nutritious, palatable food.
There are two ways to test and measure the palatability of a dog food:
First Bite: The first palatability test is called the “first bite” preference. This measures the dog's first impression of a food's aroma and appearance.
Total Volume: Because the novelty of a new diet can cause highs and lows in first-bite tests, a second test is conducted called “total volume” measurement. Total volume determines the staying power or ability of a diet to maintain the animal's interest over time. This is the dog’s overall choice of a food based on taste, texture, and nutrition for the entire test period.
In order to obtain and interpret accurate results, palatability studies must be performed by experienced animal technicians and the data analyzed by research nutritionists. Feeding studies are conducted by offering an animal two bowls of food at the same time. Each bowl contains a different diet that has been carefully weighed and recorded.
The technician observes which food the dog chooses to eat first, and then records that as the first-bite preference. After a specific time period, bowls are removed and any remaining food is weighed and recorded. Diets also are switched from left to right each day of the study to ensure that dogs are not eating one diet simply out of habit.
The total-volume measurement is determined by calculating the difference between the beginning and ending weights of each food. This procedure is repeated using the same two diets with the same group of dogs for five days. At the end of the five-day study, all observations and data are compiled and analyzed to determine the overall palatability of each diet.
Dogs are attracted by not only the taste of a food, but also to its sight, aroma, and texture. Dogs are particularly interested in the smell of food.
Liquid digest is simply protein that is enzymatically broken down into amino acids, which are the building blocks of protein. The enzymatic process reduces large protein pieces to smaller protein pieces and free amino acids. By adding small amounts of acid, the enzymatic or digestive reaction is stopped and a stable liquid ingredient is produced. After a dry-food formula is cooked, formed into kibbles, and dried, the liquid digest is sprayed evenly on the outside of the dry kibbles. This is called “enrobing.” Not only does the liquid digest make the food highly palatable, but it also adds to the overall digestibility of the food.
Yes. We use liquid digest made from chicken to enhance the palatability of dry foods and to contribute to the nutritional value of the diet. Some pet foods include flavor enhancers, such as onion powder, which simply mask the aroma and taste of the ingredients and provide no nutritional benefits to the animal.
Beet pulp is an important source of fiber that is good for helping your dog maintain intestinal health and can enhance his ability to absorb ingredients. Beet pulp is the material that remains after sugar is extracted from sugar beets.
There are two types of fiber: Nonfermentable and fermentable. Nonfermentable fiber remains undigested as it passes through a dog's intestines, providing bulk to move wastes out. Cellulose is an example of a nonfermentable fiber.
In contrast, fermentable fiber is broken down in the intestines into short-chain fatty acids that provide energy for cells that line the intestine.
Moderately fermentable fiber does both: It provides bulk to move waste and supplies energy to cells lining the intestine. Beet pulp is a moderately fermentable fiber. IAMS™ products contain a patented, moderately fermentable fiber, beet pulp, to keep your dog's digestive system healthy.
Beet pulp contains no toxins and is not harmful. It is a very safe fiber source. Beet pulp does not affect coat color. There is nothing in beet pulp that can affect coat pigment—the inside is light in color, and the dark outside peel is not used in our foods.
By definition, beet pulp is the material left over after the sugar is removed from sugar beets. Therefore, beet pulp contains no sugar.
There is no evidence that beet pulp causes bloat. Bloat (gastric dilatation-volvulus or GDV) is related to a stomach defect that delays the stomach’s emptying. It is believed that bloat is not related to diet or ingredients, such as beet pulp. However, the cause of bloat remains unknown.
IAMS has conducted extensive research on many types of fiber. The results of this research point to the fact that beet pulp maintains intestinal health and works with other nutrients to provide optimal nutrition in all of our products, including IAMS™ ProActive Health™ Adult MiniChunks. No other food manufacturer can match our formulas. Only IAMS holds a patent for moderately fermentable beet pulp.
