The calorie content of a food is dependent on the amounts of crude protein, crude fat, and carbohydrate in the product. Carbohydrates are not measured directly, but can be estimated by calculating the “nitrogen-free extract” (or NFE) in the product.
What is NFE in dog food?
The term carbohydrate, in this sheet, refers to Nitrogen Free Extract (NFE) which mainly consists of starches and sugars. Some brands of pet food have lower feeding amounts due to the formulation of their diets and different levels of digestibility.
What is NFE in animal nutrition?
Nitrogen-Free Extract (NFE) – Nitrogen-Free Extract represents the non-structural carbohydrates such as starches and sugars, and is found by difference. A newer method for evaluating the fiber fraction of feeds was developed in the 1960s by P.J. Van Soest.
What is considered high fat in dog food?
Generally a diet with less than 10% fat or less than 17% of calories from fat is considered to be low-fat. Meanwhile diets with 10-15% fat, or 17-23% of calories from fat are considered to contain a moderate amount of fat. Diets with more than 20% fat are considered high-fat.
What percentage of dog food should be carbs?
Growing animals and dogs that have high-energy needs should be fed a diet with at least 20% carbohydrates.
What is TDN?
Energy. Total Digestible Nutrients (TDN): The sum of the digestible fiber, protein, lipid, and carbohydrate components of a feedstuff or diet. TDN is directly related to digestible energy and is often calculated based on ADF.
How is NFE calculated?
Carbohydrates are not measured directly, but can be estimated by calculating the “nitrogen-free extract” (or NFE) in the product. This is determined simply by subtracting the average of each of the other components (percent crude protein, crude fat, crude fiber, moisture AND ash) from 100 [see the following example].
What are the 6 nutrients animals need?
The six essential nutrients are vitamins, minerals, protein, fats, water, and carbohydrates.
What does NFE stand for?
NFE. Not for Everyone. NFE. Non-Financial Entity (taxes)
Why are they called carbohydrates?
Etymology: Carbohydrates are called carbohydrates because the carbon, hydrogen and oxygen they contain are usually in the proportion to form water with the general formula Cn(H2O)n.
