I did all the analysis about the animal feed, fish feed to be exact. One of the analysis was NFE. Is NFE and carbohydrates is the same thing but only different term?

Nitrogen-free extract (NFE): Consisting of carbohydrates, sugars, starches, and a major portion of materials classed as hemicellulose in feeds. When crude protein, fat, water, ash, and fiber are added and the sum is subtracted from 100, the difference is NFE.
Nitrogen Free Extract (NFE)
NFE is determined by mathematical calculation. It is obtained by subtracting the sum of
percentages of all the nutrients already determined from 100.
%NFE = 100-(%moisture + %CF + %CP + %EE + %Ash)
NFE represents soluble carbohydrates and other digestible and easily utilizable non-nitrogenous substances in feed.Total carbohydrate component was crud fiber and soluble carbohydrate (NFE), NFE was the source of energy since most fishes can not digest fiber.

Dear Mohd,
I agree with Dr. Adel Al-Dubakel. In addition, you can refer to the links below.

I believe no, because crude fiber solubilizes part of lignin, which is not a carbohydrate. Besides, the NFE cannot be considered an ideal, uniform nutritional entity according to the Late Henry Lucas' statistical criteria. The important fractions is NDS (neutral detergent solubles) which include protein, ash, fat and carbohydrates soluble in neutral detergent. I recommend you the following research:
I recommend to you Mohd Khalid Khalil the paper I had recently published in Animal Feed Science and Technology, which is now available online (Apr 2018):
Silva R.S.T., Fernandes A.M., Gomes R.S., Bendia L.C.R., Silva L.C. & R.A.M. Vieira, 2018. On the specificity of different methods for neutral detergent fiber and related problems. Animal Feed Science and Technolgy, in press,https://doi.org/10.1016/j.anifeedsci.2018.04.003
There you will see an interesting discussion about specificity of fiber method and the most important difference from CF.
I also recommend to you the following conference paper:
Vieira RAM & LS Glória, 2015. Modeling Fiber Digestion Kinetics. In: Conference: 52nd Annual Metting of the Brazilian Society of Animal Science, Belo Horizonte, DOI 10.13140/RG.2.1.4678.5764.
Which contains a thorough discussion about the Lucas test and NDF.
Dear Demtew,
Practically it is not possible to get a negative value of NFE in diet.
You can use this formula for calculation or refer to this link Article Dietary protein requirement of white shrimp, Penaeus vanname...
Nitrogen free extract (NFE, g/kg) = 1000 - (g CP/kg + g EE/kg + g CF/kg + g TA/kg)
Not in its entirety as there are other nutrients like lipids and others in it in other words NFE can represent other nutrients except protein.
