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 Adult Light With Liver 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 Adult Light With Liver with a detailed discussion of the ingredients.
The first ingredient is water. Of course, water only provides moisture, which is a necessary component in wet foods.
The second 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.
The third ingredient is pork by-products. By-products are defined by AAFCO as the "non-rendered, clean parts, other than meat, derived from slaughtered mammals." Thus, pork by-products contain nearly all parts of pork 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, pork 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 pork by-products, supply many important nutrients required by dogs.
The fourth ingredient is pork liver. Pork liver is an excellent organ meat which provides high quality protein and fat. In addition, pork liver provides many essential vitamins and minerals.
The fifth ingredient 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.
Because ingredients are listed in order of pre-cooked weight, the remaining ingredients in Hill's Science Diet Adult Light With Liver 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 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.
The next 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.
Then we have 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.
Moving on, 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 with this review, 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.
The next ingredient in this review is dicalcium phosphate. Dicalcium phosphate (misnomer for dibasic calcium phosphate) is commonly used in pet food and treats as a dietary calcium supplement. It can also be found in breakfast cereals, enriched flour, noodle products, pharmaceutical tablets, and toothpastes.
Our next ingredient 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.
iodized salt is the next ingredient in this recipe. 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.
Next on the list is choline chloride. Choline chloride is member of the B-vitamin complex (vitamin B4).
The next ingredient in this recipe is potassium chloride, which is a potassium supplement.
Next we have vitamin E supplement. Vitamin E is an essential vitamin required by dogs.
The remaining ingredients in this Hill's Science Diet Adult Light 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. 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 Adult Light With Liver is 2.0 out of 5.
