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 dogs. In other words, this formula is AAFCO approved.
Unlike other AAFCO approved dog 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 Lamb provides complete and balanced nutrition for the maintenance of adult dogs.
We'll begin this review of Hill's Prescription Diet Kidney Care k/d With Lamb 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 brewers rice. Brewer's rice is the small fragments of rice kernel that are separated from the larger kernels of milled rice. The fragments do not contain the same nutrition profile of the whole kernel and therefore brewer's rice is a lower quality grain. Brewer's rice is typically regarded as an inexpensive and low quality filler.
The third 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 fourth ingredient is 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 fifth ingredient is whole grain sorghum. Whole grain sorghum is a gluten-free carbohydrate source. This cereal grain also provides a modest amount of B vitamins and minerals such as magnesium, iron, phosphorus, and manganese.
Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Prescription Diet Kidney Care k/d With Lamb 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 lamb. Although lamb is an excellent protein source, raw lamb contains more than 60% moisture. After cooking, the relative meat contribution of lamb is dramatically reduced. Therefore, it's important to ensure that other meat sources are included within the first few ingredients to ensure the product derives most of its protein from meat.
The next ingredient is dried beet pulp. Dried beet pulp is the by-product which remains once sugar has been extracted from sugar beets. The primary contribution of beet pulp is dietary fiber.
We'd also like to note that beet pulp is fairly controversial in pet food. Proponents claim that beet pulp can promote intestinal health and regulate blood sugar. However, opponents claim that beet pulp is an inexpensive filler.
Then 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.
Moving on, we have 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.
Moving on with this review, 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.
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 soybean oil. Soybean oil is an omega-6 fatty acid source. Unlike other oils (flax, canola, etc), soybean oil does not provide omega-3 fatty acids; However, the balancing omega-3 fatty acids are most likely supplied by another oil or fat source in the product.
lactic acid is the next ingredient in this recipe, which is an organic compound. Lactic acid is most likely used in this recipe as a preservative.
Next on the list is calcium carbonate. Calcium carbonate is a naturally occurring mineral supplement. Although it's often used as a dietary calcium supplement, it can also be used as a preservative or color retainer.
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.
