Dry Matter Basis (DMB) expresses the nutrient content of pet food or any other substance by removing the moisture content, allowing fair and direct comparisons across various dry food products.

By eliminating moisture levels, the DMB calculator guarantees consistent critical nutrient analysis, whether formulating homemade dog food recipes, adjusting portions, or detecting nutrient profiles.

Also, the dry matter basis calculator unveils the true contributions of ingredients listed by weight on labels.

This tool facilitates pet parents to make good choices about their pets’ dry kibble diets while aiding professionals in making perfect dietary recommendations.

Examples of Dry Matter Basis

Here are a few illustrations of the concept of Dry Matter Basis:

Canned Pet Food Products Comparison

Imagine you’re comparing two canned dog food brands. Brand A has 80% moisture, while B has 70%. Brand A’s label shows 25% protein and brand B has 30%.

To fairly compare, convert both to dry matter using a dry matter calculator.

After conversion, Brand A’s protein becomes 125% (25%/ 0.8), and Brand B’s is around 100% (30%/ 0.7); the analysis percentage reveals that Brand A has more protein on a dry matter basis.

Homemade Dog Meal Recipe

You’re creating a home-prepared meal for your puppy that consists of chicken, vegetables, and grains.

When calculating the total protein content, you must convert each fresh food ingredient to a dry food matter basis to accurately assess the nutrients your dog will receive.

For example, the chicken has 70% moisture, the vegetables boasts 90%, and the grains deliver 12%. So, the dry matter protein percentage will rank up to 144,69%.

In all these scenarios, dry matter basis guarantees proper and fair comparisons of nutrient content, assisting you in making a perfect selection for your puppy’s every diet.

So how do you calculate dry matter basis in dog food? The following is the answer.

How To Process The Dry Matter Dog Food Calculator?

Start by gathering your dog’s information, converting percentages to dry matter, calculating and summing nutrient content, estimating calories, and interpreting results for recommended portions.

Gather Information

The initial step in effectively utilizing the dog food guaranteed analysis calculator involves gathering essential data about your canine companion.

Begin by noting down key details such as the dog’s size, age, activity level, and any special dietary requirements or restrictions they may have.

Understanding your dog’s characteristics is vital, as different breeds’ nutritional needs can vary significantly.

Therefore, by meticulously gathering this information, you establish a solid framework for accurate and customized calculations with the DMB.

Convert Percentages

How do you calculate on a dry matter basis? To convert percentages, divide each nutrient’s “as-fed” percentage by the moisture content percentage expressed as a decimal.

This calculation adjusts the nutrient values to reflect what they would be without moisture.

For example, if a dog food brand specifies 25% of protein with 80% moisture, the protein percentage on a dry matter basis would be 31.25% (25% divided by 0.8).

The conversion process is a fundamental step in properly evaluating and understanding different diets’ healthy composition.

Calculate Nutrient Content

How do you calculate dry matter protein percentage? Take this formulation as an example: 

If a dog food’s dry matter basis protein percentage is 25% and the food weighs 100 grams, the protein content calculation involves multiplying 0.25 (25%) by 100 grams, resulting in 25 grams of protein.

Add Up Nutrients

You need to sum up the quantities of fat, carbohydrates, vitamins, minerals, and other key components in dog food based on their calculated dry matter content.

By consolidating these values, you can attain a snapshot of the dog food’s overall nutritional profile, ensuring that the selected food meets the desired criteria and contributes to the pet’s long-term health.

Determine Calories

Accurate calorie determination is crucial in meeting a pet’s energy needs, preventing undernutrition or overfeeding.

Calories are derived from macronutrients, each contributing a specific amount of energy per gram.

By multiplying the dry matter weight of these components by their respective calorie values, an approximation of the total calories in the canine food can be achieved.

Use the Calculator

By feeding the calculator with the aggregated information and the estimated calorie content, you allow the converter tool to analyze the data and generate a recommendation based on your puppy’s specific characteristics.

As a result, it will provide an output that suggests an appropriate portion size for your dog.

Interpret Results

Upon receiving the calculator’s output, the final step is interpreting the results to make final decisions.

The ideal portion size provided by the calculator is optimized to offer your pet the balance of nutrients and energy.

It serves as a guideline to help you determine how much food you should feed your dog each meal. Also, this assists me in calculating the required dog food by weight.

What are Ideal Dry Matter Calculator Results?

How much dry matter does a dog need? Figuring out the right DMB isn’t one-size-fits-all for dogs. It hinges on factors like age, health, activity, and whether they’re spayed/neutered.

For an active pup into sports, 40% protein might be spot-on. But a dog with kidney trouble can’t handle that.

Also, active dogs hold more fat without gaining weight than couch potatoes.

For tailored advice, your go-to option is to consult a vet or a nutritionist. They’ll help you make the best call for your furry friend.

Benefits of Using a Dry Matter Calculator
