Calculating Protein Percentages of Eggs and Peas

[Kiki]

I have some of both, I did some basic livestock nutrition in school and have done some research on my own.
Why do you ask?

Also I think another thing one needs to think about on this subject is TDN or Total Digestible Nutrition.
How we digest the nutrition of a egg is quite different than how poultry digests the nutrition of a egg.

I was just wondering/curious.

Is there an easy way to explain why counting calories like for humans is completely different when it comes to chickens?

 

[Kiki]

I'm trying to understand/figure out the way Egg is counting the calories in her calculation.

Milk will be a good one since there should be lots of information available! Lets go there.

Is there any way to set a poll at the beginning of the thread?!

But for right now lets stick to powdered eggs for a moment.

This source says 1 cup has 176 calories out of 505 being from protein. That about 34%...http://nutritiondata.self.com/facts/dairy-and-egg-products/121/2

This source says dry eggs are about 48% protein by weight... https://www.aeb.org/food-manufacturers/research-resources/nutrient-composition-tables

But 48 g X 4 calories = 184 protein calories out of 592 total is about 32%.

So which is it peeps??? I vote an AVERAGE of 33% protein from fresh eggs.

and Egg.
I am not understanding why the calorie part of the calculations here.
Someone help me!

Im not sure, I dont see where she even got she numbers at.
I see 100g [1/2 cup] of whole egg = 147 kcal
so 1 cup would be 294 kcal not 176

You must understand that not All the protein is used in the
Cellular respiration (the main cell energy manufacturing mechanism) the food intake is used for 2 main uses: 1. energy manufacturing 2.cell Building
Because that the main role of protein is structural and functional and not as a substrate for energy manufacturing it can explain the Delta between the actual protein % (34%) to the percentage of it in calories (32%) AKA Cellular respiration.

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"...

I do agree that that by weight the lower 12% would be accurate.

When it was noted that chickens eat less during warm weather... yes, less weight of feed equals less calories (energy) and it takes less energy to maintain body temp during warm weather.

I am OK if I am completely wrong... I just NEED to know WHY. Y'all are a bunch of smart peeps. I appreciate the effort to get this sorted out... big difference between feeding my birds a 12% vs 33% protein supplement even though I know the other nutrients are key.

So if you are going with the 12% protein in an egg... please tell me what you are saying is the fat content %.

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).

Please note I am reading the links and digesting the information everyone is posting, not just trying to make my case.

I did NOT know that ash was minerals left behind. Great learning!

OK... I was wondering about that part... since their is so much variable reported on different sites (but right there close), but I still just don't understand how it could count as only 12% protein when fed back as voted by kiki and casport.

This says 9.5% fat in a raw eggs
