Wysong Epigen 90 Dog Food receives the Advisor’s top rating of 5 stars.

The Wysong Epigen 90 product line includes one dry dog food, a recipe claimed to meet AAFCO nutrient profiles for adult maintenance.

The first ingredient in this dog food is chicken meal. Chicken meal is considered a meat concentrate and contains nearly 300% more protein than fresh chicken.

The second ingredient 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 third ingredient is , 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 fourth 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 fifth 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.

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.

The eighth ingredient includes chia seed, 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.

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, taurine is an important amino acid associated with the healthy function of heart muscle. Although taurine is not typically considered essential in canines, some dogs have been shown to be deficient in this critical nutrient.

Since taurine deficiency appears to be more common in pets consuming grain-free diets, we view its presence in this recipe as a positive addition.

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.

In addition, this recipe includes fish oil. Fish oil is naturally rich in the prized EPA and DHA type of omega-3 fatty acids. These two high quality fats boast the highest bio-availability to dogs and humans.

Depending on its level of freshness and purity, fish oil should be considered a commendable addition.

Next, we find yeast extract. 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 ago, 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 actual type of yeast extract included in any recipe, it’s impossible for us to judge the quality of this ingredient.

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 90 Dog Food Review

Judging by its ingredients alone, Wysong Epigen 90 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.

The dashboard displays a dry matter protein reading of 70%, a fat level of 18% and estimated carbohydrates of about 4%.

And a fat-to-protein ratio of about 25%.

Above-average protein. Above-average fat. And below-average carbs when compared to a typical dry dog food.

Even when you consider the protein-boosting effect of the chia seed, this looks like the profile of a kibble containing an abundance of meat.

Bottom line.

Wysong Epigen 90 is a grain-free dry dog food using a significant amount of named meat as its main source of animal protein, thus earning this recipe 5 stars.

Enthusiastically recommended.

As kibbles go, this one is unique. Not only is it grain free, it’s also potato free. And it possesses one of the most abundant meat contents of any dry dog food in our database.

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.
