Review of Hill's Prescription Diet Kidney Care k/d
This product is manufactured by Hill's Pet Nutrition, Inc..
According to our data, this Hill's Prescription Diet recipe provides complete & balanced nutrition for the maintenance of adult cats. In other words, this formula is AAFCO approved.
Unlike other AAFCO approved cat foods which rely in laboratory testing to substantiate nutritional adequacy, this recipe has undergone feeding trials. In the pet food industry, feeding trials are often considered to be the superior testing method.
Animal feeding tests using AAFCO procedures substantiate that Hill's Prescription Diet Kidney Care k/d With Chicken provides complete and balanced nutrition for the maintenance of adult cats.
We'll begin this review of Hill's Prescription Diet Kidney Care k/d With Chicken with a detailed discussion of the ingredients.
The first ingredient is brown rice. Brown rice is naturally rich in fiber and various minerals including manganese, phosphorus, and magnesium. Relative to other grains, brown rice is easy to digest.
The second ingredient is corn gluten meal. Corn gluten meal is a by-product from the production of various corn products (corn starch, corn syrup, etc). It's very high in protein (nearly 60% protein) and therefore can significant boost the protein content of the product. Because plant based proteins such as corn gluten meal are inferior to meat based proteins (lack many essential amino acids), they are not suitable substitutes.
The third ingredient is chicken. Chicken is the most common meat ingredient used in cat food. It provides high-quality protein and fat. However, more than 60% of chicken is water.
The fourth ingredient is pork fat. Pork fat is typically collected while cooking pork using a process called rendering. Pork fat is a relatively high quality source of essential fatty acids. In particular, pork fat is high in linoleic acid, an important omega-6 fatty acid.
The fifth ingredient is whole grain wheat. Whole grain wheat contains the entire grain of wheat (the germ, bran, and endosperm). Wheat is the second most-produced cereal grain in the world (corn is the first). Although wheat is a controversial ingredient, it is not necessarily undesirable because it provides dietary fiber and many other nutrients. However, wheat contains a notable amount of plant based protein, which is inferior to meat based protein and therefore an undesirable substitution.
Wheat is also one of the most common ingredients to cause food allergies or intolerance. However, grains such as wheat are typically low offenders in comparison to certain protein sources (such as beef).
Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Prescription Diet Kidney Care k/d With Chicken are not as important as the first five ingredients.
However, collectively they still have a significant impact on the overall quality of the product. Therefore, we'll continue discussing the remaining ingredients in this Hill's Prescription Diet recipe.
Next we have cracked pearled barley. Cracked pearled barley is barley with the outer husk and bran layers removed. Similar to regular barley, cracked pearled barley provides carbohydrates and dietary fiber. Cracked pearled barley is however not as nutritious as regular whole grain barley.
The next ingredient is wheat gluten. Wheat gluten is the main protein of wheat. Although wheat gluten is mostly protein, wheat gluten is considered controversial because it significantly boosts the protein content of the product. This is undesirable because plant based protein does not provide the same amino acid profile as meat based protein.
Then we have natural chicken liver flavor. As the name implies, natural chicken liver flavor provides chicken liver flavor to the product. This particular flavor is derived from natural sources which may or may not include real chicken liver.
Moving on, we have pea protein. Pea protein is produced by removing the starchy parts of peas. Pea protein is considered controversial because it provides a substantial plant based protein boost. This boost is undesirable because plant based protein is typically lower in biological value when compared to meat based proteins.
Moving on with this review, we have egg product. Egg product consists of shell-free eggs which are easy to digest and contain high quality protein. Egg protein is often given the highest biological value (BV). The BV metric measures the usability of the ingredient's protein.
The next ingredient in this review is fish oil. Fish oil is defined by AAFCO as "the oil from rendering whole fish or cannery waste." It is typically rich in omega-3 fatty acids and therefore a good fat source. However, the specific fish used to obtain the oil is not specified and therefore we cannot make any specific claims.
Our next ingredient is lactic acid, which is an organic compound. Lactic acid is most likely used in this recipe as a preservative.
The remaining ingredients in this Hill's Prescription Diet Kidney Care k/d recipe are unlikely to affect the overall rating of the product.
Our analysis of the ingredients show that this product derives a substantial amount of protein from non-meat ingredients. Since this product is a prescription diet, this property may be required and therefore we cannot make any further statements.
In summary, we recognize that this product does not contain any artificial colors, artificial preservatives, or anonymous meat ingredients.
