Review of Hill's Prescription Diet Aging Care g/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 Aging Care g/d Chicken Flavor provides complete and balanced nutrition for the maintenance of adult cats.
We'll begin this review of Hill's Prescription Diet Aging Care g/d Chicken Flavor with a detailed discussion of the ingredients.
The first 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 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 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 chicken by-product meal. Chicken by-product meal is produced by cooking chicken by-products using a process called rendering. By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, chicken by-products contain nearly all parts of chickens which are typically not consumed by humans. These parts include the liver, lung, spleen, kidney, stomach, blood, intestine, bone, etc.
Like other meat by-products, chicken by-products are considered controversial, mainly because they are inexpensive ingredients which consumers have equated with slaughterhouse waste. However, manufactures and many experts claim that animal by-products are unjustly criticized. Proponents state that "named" by-products, such as chicken by-products, supply many important nutrients required by cats.
The fifth ingredient is pork protein isolate. According to AAFCO, "Meat Protein Isolate is produced by separating meat protein from fresh, clean, unadulterated bones by heat processing followed by low temperature drying to preserve function and nutrition." Pork protein isolate ingredient contains a minimum of 90% protein, maximum of 1% fat and 2% ash.
Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Prescription Diet Aging Care g/d Chicken Flavor 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 soybean mill run. Soybean mill run is the by-product of dehulled soybean meal production. This ingredient is for the most part made up of soybean hulls, which are nutritionally empty. Many pet owners and experts believe soybean mill run is an inexpensive low quality filler and therefore we've marked soybean mill run a controversial ingredient.
The next ingredient is lactic acid, which is an organic compound. Lactic acid is most likely used in this recipe as a preservative.
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 calcium sulfate. Calcium sulfate is a food additive that helps control acidity levels and functions as a firming agent. It's not a desirable ingredient, but it is considered safe by the FDA in small quantities.
Moving on with this review, we have fish meal. Fish meal is defined by AAFCO as "the clean, dried, ground tissue of undecomposed whole fish or fish cutting, either or both, with or without the extraction of part of the oil." Since the specific type of fish is not mentioned, we cannot discuss any specific qualities of this ingredient. In general, anonymous ingredients are low quality inclusions when compared to ingredients such as tuna meal, salmon meal, catfish meal, etc.
The next ingredient in this review is choline chloride. Choline chloride is member of the B-vitamin complex (vitamin B4).
Our next ingredient is potassium chloride. Potassium chloride is a potassium supplement.
The remaining ingredients in this Hill's Prescription Diet Aging Care g/d recipe are unlikely to affect the overall rating of the product.
Our analysis of the ingredients show that this product derives a considerable 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 contains anonymous meat ingredients. These are not necessarily always negative; however, they are typically low quality and inexpensive additions. If the particular anonymous meat ingredient is controversial or low quality, it should have been discussed earlier in this review. Otherwise, it is safe to assume the anonymous meat ingredient is an acceptable addition.
