Before you assume that by-products in kitten food are bad thing, here are some facts. In common usage, a by-product is something that is just that—a side product from the making of another product. By-products are not by definition poor quality. For instance, gingerbread cookies wouldn’t be the same without molasses, which is a by-product of sugar manufacture.
In relation to IAMS™ kitten foods, such as IAMS ProActive Health™ Kitten, by-products are generally parts of the animals that are not the muscle meat preferred by most American consumers. The term refers only to the anatomic parts included, not to the nutritional quality of the parts.
While many Americans may not be used to eating these animal parts themselves, it is important to realize that many of the items included in by-products (e.g., organ meats) may be higher in essential nutrients—amino acids, minerals, and vitamins—as well as more palatable to pets than the skeletal muscle meat.
In addition to nutritional benefits, inclusion of these ingredients in pet foods reduces waste and likely has environmental benefits as the livestock industry does not have to produce additional animals just to satisfy the needs for muscle meats to feed pets as well as people. Feeding these nutrient-rich, tasty parts to pets may prevent them from being wasted and allows the entire animal to be put to good use.
Much of the consumer confusion and discomfort surrounding by-products most likely stems from the marketing strategies of some pet food brands and perhaps from the ingredient name “by-product” itself.
It is important to keep in mind that most ingredients in pet foods can vary greatly in quality. In addition, quality cannot be assessed purely on the basis of the ingredient list. All by-products are not the same quality. Neither is all muscle meat. There are very high-quality by-products as well as poor-quality chicken and chicken meal (or beef or pork).
Purchasing food only from reputable manufacturers who are very selective about their suppliers, have full-time, qualified nutritionists, and perform analytical testing to ensure that every ingredient, as well as the finished product, meets their exact nutrient specifications, will help avoid problems due to poor-quality ingredients.
High fibre cat food has become a mainstay for many cats with gastrointestinal problems. But why is fibre so crucial for cats?
Fibre is a type of carbohydrate that isn't digested by a cat's gastrointestinal tract. It is important for cat health because it provides bulk to move food through. Some types of fibre can be fermented (broken down by bacteria) in the system. This process creates short-chain fatty acids (SCFA), which are an important energy source for the cells lining the intestinal tract.
Thus, understanding the various types of fibre and when to include fibre in a cat's nutrition plan is crucial. High-fibre cat food often contains a combination of soluble and insoluble fibres that aid gastrointestinal health and improve stool quality. Some of these fibre elements are also known as prebiotics, which are nutrients (mostly fermentable fibres) that help the good bacteria in the intestines grow.
Soluble fibre for cats, such as gums and pectins, are the best at absorbing water. These fibres are typically highly fermentable and provide the required energy source. Adding such soluble fibres to your cat’s diet can help it maintain a healthy colonic mucosa and boost immune function in the lower intestine.
Insoluble fibres, such as lignin or cellulose, have a variety of therapeutic properties and can be utilised in your cat’s meal to promote its gastrointestinal health.
Today, people are more aware of fibre and its role in their diet. Studies showing the beneficial effects of higher fibre levels in humans influence the way many people think about their own food and that of their pets. Some manufacturers now apply the recommendations of human nutritionists and make high-fibre diets for cats, but cats have a much shorter digestive tract than we do. And unlike humans, cats are carnivorous, so their nutritional needs are better satisfied with meat rather than plant matter. Therefore, cats have different dietary needs than humans. For more than 60 years, companion animal nutritionists at IAMS™ have been studying diets to meet the special nutritional needs of cats.
Furthermore, fibre-rich cat food benefit cats suffering from GI illnesses of the large intestine. Fibrous food can assist in preserving their GI motility and water balance. This is turn helps prevent constipation and diarrhea in cats.
IAMS Company research shows the optimal crude fibre level for healthy cat’s ranges from 1.4% to 3.5%. At these levels, nutrient breakdown is maximised. In unique situations, such as hairballs, higher fibre levels may be beneficial.
An important characteristic of fibre is its fermentability, or how well it can be broken down by bacteria in the intestine. This breakdown produces short-chain fatty acids, which provide energy to the intestines. Fibre varies in fermentability. Fibre sources used in pet foods include cellulose, which is poorly fermentable; beet pulp, which is moderately fermentable; and gums and pectin, which can be highly fermentable. Research has shown that moderate levels of moderately fermentable fibre, such as beet pulp, provide the benefits of energy for the intestinal lining and bulk, without the negative effects of excessive stool or gas and, therefore, are beneficial in cat diets.
High moisture, protein, and minimum carbohydrate matter are all key ingredients in high-fibre cat diets. Here are some benefits of high-fibrous food for your cat:
Cats with medical issues can also greatly benefit from high-fibre foods. For instance, high-fibre wet cat food might help overweight cats in reducing overeating and lowering their risk of obesity. What’s more is, adding fibrous food to your cat’s meal will also help your pet eliminate more nitrogen through their stool, thus sparing the kidneys. In fact, many dietary fibres inhibit nutrient absorption qualities, which help to lessen the rate at which the GI tract assimilates glucose, thereby keeping the blood sugar levels stable.
High levels of poorly fermentable fibre are used in some weight-reduction pet foods to dilute the calories in a serving. IAMS Company research shows that high fibre in cat food can make it harder to digest other nutrients in the meal and, in turn, reduce the nutritional quality of a feline’s diet. Your cat making more trips to the litter box can be a result.
Low-fibrous food contains nutrients such as electrolytes and B-vitamins that aid recuperation in cats. This type of food is usually recommended by veterinarians for cats who are prone to having a quick onset of GI disturbance. Therefore, when choosing a meal for your cat, always visit a veterinarian. If your cat is on a high-fibre diet, their veterinarian should keep an eye on them to ensure that their fibre-responsive symptoms are under control.
When choosing a pet food, fibre is an important consideration, but remember that the needs of cats are not the same as those of humans. A moderate level of moderately fermentable fibre, such as beet pulp, provides proven nutritional benefits for cats. Cat diets containing high levels of poorly fermentable fibre dilute calories and deprive cats of the nutrients they need.
All IAMS products are made with levels of moderately fermentable fibre needed to promote intestinal health. And all IAMS foods, such as IAMS ProActive Health™ Adult Original with Chicken, contain the moderately fermentable fibre system, which is the exclusive property of IAMS Company and is protected by U.S. Patent No. 5,616,569 for Pet Food Products Containing Fermentable Fibres and Process for Treating Gastrointestinal Disorders.
