Calculating Protein Percentages of Eggs and Peas

[X_and_Z]

Yes they do look the same other than calcium.
I agree that dry verses wet will give different numbers. Wet weight verses calories But when using the powdered egg factor... the numbers still added to about 33%... even according to a post by @Akrnaf2. Whether you you go dry or wet... using calories the numbers are the SAME. Using weight it is not... totally makes sense to me since water doesn't count.

You guys really are being good sports about this!

Dry egg is 35% protein by calories but 47.5% protein by weight. Since fat has more than 2X the number of calories per gram than carbohydrates the percentages will be skewed. Chicken feed labels are either per dry weight or "As Fed" (which on a low moisture food is close to dry weight) so you can't compare them with numbers for egg based on calories unless you do some math to convert.

For example, a dry food that has 1g carbohydrate and 1g protein and 1g fat will be:
On a dry matter basis:
33.33% carbohydrate
33.33% protein
33.33% fat
On a per calorie basis:
23.5% carbohydrate
23.5% protein
52.9% fat

You are correct I am focusing on caloric content because according to even a couple of the things you have posted... "chickens will eat to meet their ENERGY need"...

Though our stomach and crops may limit how much we can take in. I believe our metabolism (and chickens/other animals regardless of digestion process) regulates the ENERGY (caloric).

Couple things here (1) humans don't have crops, (2) we like a lot animals do not regulate our eating by a need for energy like poultry do.

Now more important than the total fat of a ingredient is the total caloric amount and how that breaks down in a birds system.

Metabolizable energy (AMEn)
True metabolizable energy (TMEn).
Energy of maintenance (NEm)
Growth and reproduction is called the net energy for production (NEg).

I don't care about absorption... I wanna know if I am feeding my animals 12% or 33% protein and the correlating % of fat when I feed a raw or even cooled egg (not powdered) back to my animals. And I don't want to spread it as a "high" protein supplement (regardless of other nutrients) if it's ONLY 12%.

It really doesn't matter !! 12% from 50 grams row egg are 6 grams of protein if you dry the egg and get 15 grams of powder it is still 6 grams of protein. The problem begins when you give them 50 grams of POWDERED eggs and thinking that 50 grams of POWDERED eggs is equivalent to ONE egg.

And egg has 6 grams of protein.
To figure out the percentage of this 6 grams of protein for a chicken's diet would be calculated how?
We would need to know the exact amounts of everything else the chicken ate that day right?

 

[Kiki]

Maybe a better question is...how many grams of protein does a chicken need per day?

 

[Kiki]

No, it depends on the composition of the other 82%!

Wow

I agree with you and understand what you are saying.

In a fresh egg... not comparing it to chicken feed or dried, not based on a daily recommended allowance for humans... What say you is the protein percent??

I would always compare by dry weight so it would be 45-50%. But I think dry weight comparisons give the most accurate picture of a food. Not everyone agrees

 

[Kiki]

I can't agree with myself right now.

Yes.
