Even if a cat food is formulated to provide all of the essential nutrients, it is of little value if the cat won’t eat it. Quality cat foods are carefully formulated not only to be highly nutritious, but to be highly palatable as well.
Palatability is a term used to describe how well a cat likes the taste, smell, and texture of a food. A premium pet 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 cat food:
First bite: The first palatability test is called the first bite preference, and measures the cat'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, the total volume measurement, is conducted. Total volume determines the staying power, or ability of a diet to maintain the animal's interest over time. This is the cat's overall choice of 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, with 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 animal chooses to eat first, 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 are also switched from left to right each day of the study to ensure that animals 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 or cats 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.
Cats are attracted by not only the taste of a food, but also by the sight, aroma, and texture. Cats can be very particular about the shape and size of dry food kibbles and also prefer a food with an acidic taste.
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.
Every kitten food has protein, but here are some important facts about the different types of protein to help you choose the right food for your kitten. It is important to remember that the source of protein is vitally important to kittens because one of the principle nutritional philosophies is that kittens are best fed as carnivores.
Some pertinent facts when listening to the claims and advertising of various manufacturers:
1. Recommended kitten food protein levels are established by nutrition experts from around the world and published as NRCs (Nutrient Reference Charts). These protein requirement levels are determined by meeting the animal’s need for essential amino acids, the building blocks of protein; and by monitoring/calculating the nitrogen balance (a comparison between the intake of nitrogen in the diet and the losses through urine, feces, and evaporation from the skin and mouth). Nitrogen balance has been the recognized method of determining protein requirements for many decades. Variations in levels from what has been established for many years should be validated by convincing research. If the change in level isn’t backed by supporting evidence of a tangible benefit, then there may be hazards. Studies in several species have found a link between diets with high protein levels (greater than 40% protein), bone loss, and urinary tract stones.
2. Protein from plant sources may elevate the amount of protein, but may not be as beneficial as animal-based sources of protein in kitten food because of lower digestibility, effects on muscle-to-fat body composition ratio, and the range of amino acids they provide.
3. There are only three sources of energy in any kitten food diet–fat, protein, and carbohydrate (starch). If the amount of one element is raised, the amount of one or two of the others must be lowered to maintain a proper energy level in the food for your kitten’s life stage and lifestyle. A balance of nutrients is important to your kitten because each of the nutrient groups supplies something very specific for the kitten’s body. Excess protein above your kitten’s actual needs cannot be stored for future use and will be converted into fat.
