Chicken, Rice & Barley Recipe
This product is manufactured by Hill's Pet Nutrition, Inc..
According to our data, this Hill's Science Diet recipe provides complete & balanced nutrition for the maintenance of adult dogs. In other words, this formula is AAFCO approved.
Hill's Science Diet Oral Care Adult Chicken, Rice and Barley Recipe is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for the maintenance of adult dogs.
We'll begin this review of Hill's Science Diet Oral Care Adult Chicken, Rice and Barley Recipe with a detailed discussion of the ingredients.
The first ingredient is chicken. Although chicken is an excellent protein source, raw chicken contains more than 60% moisture. After cooking, the relative meat contribution of chicken 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 second 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).
The third ingredient is powdered cellulose. Powdered cellulose is produced from minuscule pieces of wood pulp and plant fibers. Other than its fiber content, powdered cellulose lacks any nutritional contribution.
The fourth 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 fifth ingredient is chicken fat. Chicken fat is typically collected while cooking chicken using a process called rendering. Chicken fat is a relatively high quality source of essential fatty acids. In particular, chicken fat is high in linoleic acid, an important omega-6 fatty acid.
Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Science Diet Oral Care Adult Chicken, Rice and Barley Recipe 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 Science Diet recipe.
Next we have chicken meal. Chicken meal is produced by cooking chicken using a process called rendering. The rendering process dramatically reduces the natural moisture of chicken and thereby results in a highly condensed protein source.
The next ingredient is whole grain corn. Whole grain corn is the entire corn kernel (the germ, bran, and endosperm). Corn is a cereal grain which provides a modest amount of vitamins, minerals, and plant based protein. It also happens to be one of the most controversial ingredients in dog food.
Proponents of corn claim that corn is highly digestible and an excellent source of protein, energy, vitamins, minerals, and essential fatty acids.
Opponents however believe that positive claims in regards to corn are either half-truths or completely false, we'll discuss a few of the opposing arguments.
In regards to digestibility, the claims of "highly digestible" are only true if corn is processed into a meal or flour and subsequently cooked. In regards to the protein contribution, we must note that corn is a plant based protein which does not contain all of the necessary amino acids required by dogs to sustain life. Therefore substituting corn for meat is an unsuitable substitution and actually degrades the overall protein quality of the product.
Finally, we'll discuss the claims about vitamins and minerals in corn. Although corn does provide many vitamins and minerals, it not necessarily an exceptional ingredient in this regards. There are many other ingredients which are more complete and biologically appropriate. Therefore the usage of corn as the primary ingredient in dog food should certainly warrant further questioning.
Then 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, 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.
Moving on with this review, we have 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.
The next ingredient in this review is 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.
Our next ingredient is whole grain oats. Whole grain oats provide a notable amount of dietary fiber, B vitamins, and various minerals. Whats more, non-contaminated oats are gluten free; however, oats are typically processed and grown near ingredients which contain gluten and therefore contamination is not unusual. Always check the packaging to ensure the product is gluten free if your pet has allergies to gluten.
wheat gluten is the next ingredient in this recipe. 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.
Next on the list is 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 in this recipe is natural pork flavor. As the name implies, natural pork flavor provides pork flavor to the product. This particular flavor is derived from natural sources which may or may not include real pork.
Next 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.
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 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.
Moving on, we have 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.
Moving on with this review, we have potassium chloride. Potassium chloride is a potassium supplement.
The next ingredient in this review 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.
Our next ingredient is iodized salt. Iodized salt is simply table salt mixed with very small amounts of iodine-containing salt. Iodine is an important natural element required by dogs to maintain good health.
calcium carbonate is the next ingredient in this recipe. 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.
Next on the list is choline chloride. Choline chloride is member of the B-vitamin complex (vitamin B4).
The remaining ingredients in this Hill's Science Diet Oral Care Adult 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. This is an undesirable property because plant based protein often lacks many of the necessary amino acids required by dogs. This property is typically found in lower quality products.
In summary, we recognize that this product does not contain any artificial colors, artificial preservatives, or anonymous meat ingredients.
The official PawDiet rating for Hill's Science Diet Oral Care Adult Chicken, Rice and Barley Recipe is 2.0 out of 5.
