The first ingredient in this dog food is organic 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 turkey meal, another protein-rich meat concentrate.
The fourth ingredient is potato protein, the dry residue remaining after removing the starchy part of a potato.
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 actual meat content of this dog food.
The fifth ingredient is meat protein isolate, a product made by “separating meat protein from fresh, clean, unadulterated bones by heat processing followed by low temperature drying to preserve function and nutrition. This product is characterized by a fresh meaty aroma, a 90% minimum protein level, 1% maximum fat and 2% maximum ash”.1
Contrary to what the name would normally imply, this item is not generic. According to Wysong (on its website), this ingredient is derived exclusively from pork meat.
This is a quality source of meat-based protein.
The sixth ingredient is chicken fat. Chicken fat 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 seventh ingredient is gelatin, a colorless, flavorless, translucent, brittle substance that’s irreversibly derived from the collagen found in the skin and bones of animals.
Although it consists mostly of protein (98-99% non-essential amino acids), gelatin is of only limited nutritional value to a dog.
The eighth ingredient is beet fiber. Beet fiber is the refined by-product derived from sugar beet production. This item is most likely included here for the usual benefits of dietary fiber.
After the natural flavor we find coconut oil, a natural oil rich in medium-chain fatty acids.
Medium-chain triglycerides have been shown to improve cognitive function in older dogs.2
Because of its proven safety3 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.
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 product.
With five notable exceptions…
First, chia seed is an edible seed nutritionally similar to flax or sesame. Provided they’re first ground into a meal, chia seeds are rich in both omega-3 fatty acids as well as dietary fiber.
However, chia seeds contain about 17% protein, a factor that must be considered when judging the meat content of this dog food.
Next, tomato pomace is a controversial ingredient, a by-product remaining after processing tomatoes into juice, soup and ketchup.
Many praise tomato pomace for its high fiber and nutrient content, while others scorn it as an inexpensive pet food filler.
Just the same, there’s probably not enough tomato pomace here to make much of a difference.
In addition, yeast extract is the common name for a broad group of products made by removing the cell wall from the yeast organism.
A significant number of these ingredients are added as specialized nutritional supplements while others are used as flavor enhancers.
However, the glutamic acid (and its chemical cousin, monosodium glutamate, or MSG) found in a minority of yeast extracts can be controversial.
That’s because even though the Food and Drug Administration designated these food additives to be safe decades ago4, the agency continues to receive reports of adverse effects.
So, detractors still object to the use of yeast extract and other glutamic acid derivatives and blame them for everything from Alzheimer’s (in humans) to obesity.
In any case, since the label reveals little about the the actual type of yeast extract included in any recipe, it’s impossible for us to judge the quality of this ingredient.
Next, chicory root is rich in inulin, a starch-like compound made up of repeating units of carbohydrates and found in certain roots and tubers.
Not only is inulin a natural source of soluble dietary fiber, it’s also a prebiotic used to promote the growth of healthy bacteria in a dog’s digestive tract.
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.
Wysong Epigen Dog Food Review
Judging by its ingredients alone, Wysong Epigen dog food looks like an above-average dry product.
But ingredient quality by itself cannot tell the whole story. We still need to estimate the product’s meat content before determining a final rating.
And a fat-to-protein ratio of about 25%.
Above-average protein. Near-average fat. And below-average carbs when compared to a typical dry dog food.
Even when you consider the protein-boosting effect of the potato protein and chia seed, this looks like the profile of a kibble containing an abundance of meat.
By the way, what impresses us most here isn’t the extraordinary protein content of these products. It’s actually the unique process Wysong uses to avoid the starchy binders normally required for making any kibble.
A process which can cap the meat content of most dry dog food recipes at well under 40%.
But Wysong claims its Epigen product contains 60% meat. What’s more, our computations project a a carb content here of an exceptionally low 9%.
In addition, those looking to mimic a dog’s natural ancestral diet should find Wysong Epigen an appropriate choice.
Wysong Epigen is a meat-based dry dog food using an abundance of named meat meals as its main sources of animal protein, thus earning the brand 5 stars.
Please note certain recipes are sometimes given a higher or lower rating based upon our estimate of their total meat content and (when appropriate) their fat-to-protein ratios.
