How do you calculate dry matter basis for cat food?

How do you calculate dry matter basis for cat food?

Subtract the dog food’s moisture content percentage from 100%. Divide a nutrient’s as-fed basis percentage by the difference you got from the previous step. Multiply this quotient by 100% to obtain the dry matter percentage of that nutrient.

What is dry matter basis in cat food?

Dry matter basis is the nutrient profile of a food without accounting for the moisture in the food. As you can image, comparing the 40% protein kibble and the 10% protein wet food looks quite different when you remove moisture from the equation.

What does guaranteed analysis mean on cat food?

Guaranteed Analysis. At minimum, many state regulations require a pet food to guarantee the minimum percentages of crude protein and crude fat, and the maximum percentages of crude fiber and moisture. The “crude” term refers to the specific method of testing the product, not to the quality of the nutrient itself.

Is guaranteed analysis dry matter basis?

Even if the guaranteed analysis gave exact percentages, rather than just minimums and maximums, these numbers don’t help us to compare nutrients in pet foods because the guaranteed analysis numbers are on what’s called an “as-fed” basis, meaning they include all the water in the diet, which varies widely between dry.

How do you convert dry matter?

1) Figure the dry matter percentage. Subtract the moisture content from 100%. In this example 100% – 75.9% = 24.1% dry matter. 2) Convert individual nutrients from “as fed” to “dry matter”.

How do you calculate dry matter basis?

To calculate the protein on a dry matter basis, you remove the water, so 100 g powder – 5.3 g water = 94.7 grams of dry matter. You convert from “as is” to DMB by taking the percentage protein on a DMB basis and dividing by the new percentage of dry product: % protein DMB = as is protein / (1- % water).

What is true about dry matter basis?

What is Dry Matter Basis? Dry matter basis is a representation of nutrients (i.e. protein, fat, and fiber) which ignores the moisture content of the food. In other words, it’s the amount of protein, fat, and fiber which would be reported if the product’s moisture were completely removed.

What does dry matter basis mean?

So, when comparing the nutrient content of different products, it’s important to first remove 100 percent of the moisture content from every dog food being evaluated. This moisture-free approach to stating the true nutrient content of any food is known as dry matter basis.

Is guaranteed analysis per serving?

Pet food regulations require that all pet foods provide the petsumer with ‘guaranteed analysis’ information on the label. Interestingly, the Wellness website provides additional information to the Guaranteed Analysis. It is stated as “As Served Per Can”. The ‘as served’ analysis states…Protein 12%, Fat 11%.

How much does nutrition label cost?

The costs can quickly add up. A lab analysis for Nutrition Facts nutrients and proximates averages about $800-1,000 per sample, and analysis for any extra nutrients could run up to $100 each. Every time you modify an ingredient or recipe, you have to pay for a new analysis.

How do you calculate dry matter for feeds?

Why dry matter is important?

Dry matter is an indicator of the amount of nutrients that are available to the animal in a particular feed. Livestock need to consume a certain amount of dry matter per day (measured in lbs or kg/day) to maintain health and production.

How do you compare cat food on a dry matter basis?

Comparing cat food on a “dry matter basis,” often designated simply as “DMB,” takes into account the differences in water content so just the nutrients can be compared on a common basis. Take one tablespoon of protein powder that weighs half an ounce. Add 8 ounces of water to it.

What is the percentage of moisture in cat food?

For example, the GA for moisture on a can of cat food may be listed as 70 percent, which equals 30 percent dry matter (100 percent minus 70 percent). Next, for each product, divide the reported nutrient level you are interested in comparing by that product’s dry matter percentage.

What is a dry matter basis in nutrition?

Dry matter basis is a representation of nutrients (i.e. protein, fat, and fiber) which ignores the moisture content of the food.

How do you calculate 100% protein in cat food?

Food 2: 3% (protein listed on the guaranteed analysis) ÷ 3% (the amount of dry matter content in the food) = 100%. Each food is 100% protein on a dry matter basis. But there’s more than just protein in cat food. Here is an example of how to convert the guaranteed analysis provided on cat food labels to a dry matter basis.
