|Estimated Nutrient Content|
|Dry Matter Basis||29%||18%||45%|
|Calorie Weighted Basis||25%||37%||38%|
The first ingredient in this dog food is chicken. Although it is a quality item, raw chicken contains up to 73% water. After cooking, most of that moisture is lost, reducing the meat content to just a fraction of its original weight.
After processing, this item would probably account for a smaller part of the total content of the finished product.
The second ingredient is chicken meal. Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.
The third ingredient is oatmeal, a whole-grain product made from coarsely ground oats. Oatmeal is naturally rich in B-vitamins, dietary fiber and can be (depending upon its level of purity) gluten-free.
The next ingredient is barley, a starchy carbohydrate supplying fiber and other healthy nutrients. However, aside from its energy content, this cereal grain is of only modest nutritional value to a dog.
The fifth ingredient includes chickpeas, also known as garbanzo beans. Like peas, bean and lentils, the chickpea is a nutritious member of the fiber-rich legume (or pulse) family of vegetables.
However, chickpeas contain about 22% protein, a factor that must be considered when judging the actual meat content of this dog food.
The sixth ingredient lists peas. Peas are a quality source of carbohydrates. And like all legumes, they’re rich in natural fiber.
However, peas contain about 25% protein, a factor that must be considered when judging the meat content of this dog food.
The next ingredient is pea protein, what remains of a pea after removing the starchy part of the vegetable.
Even though it contains over 80% protein, this ingredient would be expected to have a lower biological value than meat.
And less costly plant-based products like this can notably boost the total protein reported on the label — a factor that must be considered when judging the meat content of this dog food.
The eighth ingredient is coconut oil, a natural oil rich in medium-chain fatty acids.
Medium-chain triglycerides have been shown to improve cognitive function in older dogs.1
Because of its proven safety2 as well as its potential to help in the treatment of canine cognitive dysfunction syndrome (CDS) and chronic skin disorders, MCT can be considered a positive addition to this recipe.
The ninth ingredient is chicken fat. This item is obtained from rendering chicken, a process similar to making soup in which the fat itself is skimmed from the surface of the liquid.
Chicken fat is high in linoleic acid, an omega-6 fatty acid essential for life. Although it doesn’t sound very appetizing, chicken fat is actually a quality ingredient.
The tenth ingredient is sunflower seed meal, a by-product of the oil extraction process – and an item more typically found in feed for livestock.
Although sunflower meal contains about 34% protein, it would be expected to have a lower biological value than meat.
And less costly plant-based products like this can notably boost the total protein reported on the label — a factor that must be considered when judging the actual meat content of this dog food.
From here, the list goes on to include a number of other items.
But to be realistic, ingredients located this far down the list (other than nutritional supplements) are not likely to affect the overall rating of this Castor and Pollux product.
With 5 notable exceptions…
First, we find flaxseed, one of the best plant sources of healthy omega-3 fatty acids. Provided they’ve first been ground into a meal, flax seeds are also rich in soluble fiber.
However, flaxseed contains about 19% protein, a factor that must be considered when judging the actual meat content of this dog food.
Next, although alfalfa meal is high in plant protein (about 18%) and fiber (25%), this hay-family item is more commonly associated with horse feeds.
In addition, we note the use of sunflower oil. Sunflower oil is nutritionally similar to safflower oil. Since these oils are high in omega-6 fatty acids and contain no omega-3’s, they’re considered less nutritious than canola or flaxseed oils.
Sunflower oil is notable for its resistance to heat damage during cooking.
There are several different types of sunflower oil, some better than others. Without knowing more, it’s impossible to judge the quality of this ingredient.
Next, we note the inclusion of dried fermentation products in this recipe. Fermentation products are typically added to provide enzymes to aid the animal with digestion.
And lastly, this food contains chelated minerals, minerals that have been chemically attached to protein. This makes them easier to absorb. Chelated minerals are usually found in better dog foods.
Since this recipe contains a number of organic ingredients, we feel compelled to grant this line a more favorable status as we consider its final rating.
That’s because organic ingredients must comply with notably more stringent government standards — standards which significantly restrict the use of any synthetic pesticides, herbicides, insecticides, hormones or antibiotics.
With that in mind…
Based on its ingredients alone, Castor and Pollux Organix Dog Food looks like an above-average dry product.
As a group, the brand features an average protein content of 29% and a mean fat level of 18%. Together, these figures suggest a carbohydrate content of 45% for the overall product line.
And a fat-to-protein ratio of about 60%.
Which means this Castor and Pollux product line contains…
Above-average protein. Above-average fat. And below-average carbs when compared to a typical dry dog food.
When you consider the protein-boosting effect of the chickpeas, peas, pea protein, sunflower seed meal, flaxseed and alfalfa meal, this looks like the profile of a kibble containing a notable amount of meat.
