Ingredients Analysis
The first ingredient is turkey necks, raw turkey neck consists of muscle meat and bone and is a source of chondroitin which supports joint health.
The second ingredient is turkey. Turkey is considered “the clean combination of flesh and skin… derived from the parts or whole carcasses of turkey”.1
Turkey is naturally rich in the 10 essential amino acids required by a dog to sustain life.
The third ingredient is turkey liver. This is an organ meat sourced from a named animal and thus considered a beneficial component.
The fourth ingredient is turkey gizzard. The gizzard is a low-fat, meaty organ found in the digestive tract of birds and assists in grinding up a consumed food. This item is considered a canine dietary delicacy.
The fifth ingredient is carrots. Carrots are rich in beta-carotene, minerals and dietary fiber.
The sixth ingredient is squash. Squash is a nutritious addition high in complex carbohydrates, vitamins, minerals and dietary fiber.
The seventh ingredient is lettuce. This green leafy vegetable is naturally rich in vitamins and minerals. Different varieties of lettuce vary in their nutritional content but lettuce is low in calories, provides fiber, and supports hydration.
The eighth ingredient is sweet potato. Sweet potatoes are a gluten-free source of complex carbohydrates in a dog food. They are naturally rich in dietary fiber and beta carotene.
The ninth ingredient is celery, although raw celery can be very high in water, it can still contribute a notable amount of dietary fiber as well as other healthy nutrients.
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 the product.
This recipe has two notable exceptions.
First, flaxseed oil, one of the best non-fish sources of omega-3 fatty acids – essential to a dog’s health.
Next, cod liver oil, a fish oil known to be rich in both EPA and DHA omega-3 fatty acids as well as vitamins A and D.
Nutrient Analysis
Based on its ingredients alone, Darwin’s Biologics Turkey looks like an above-average raw product.
The dashboard displays a dry matter protein reading of 53.4%, a fat level of 24.1% and an estimated carbohydrate level of 6.9%.
As a group, the brand features a protein content of 50.9% and a mean fat level of 25.6%. Together these figures suggest a carbohydrate content of 10% for the overall product line, alongside a fat-to-protein ratio of 51%.
This means that Darwin’s BioLogics Raw product range contains above-average protein, below-average carbohydrate, below below-average fat when compared to typical raw dog food.
