Calculating Protein Percentages of Eggs and Peas

[EggSighted4Life]

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

This was based on powdered egg and 176 was the calories from protein not the total of 505. It came from the link that I re-quoted here...

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

I think what is confusing me is that on say a bag of chicken feed there is not a calorie number. I don't count the calories in the amount of feed I feed out I count it by weight.
So this whole calorie things is screwing me up.



I still haven't figured it out so I can't explain yet.

I will get there.

I agree, they don't put calorie content on our feeds... but I can tell you that flock raiser and layer do not have the same caloric count by weight.... SO??? I did see one person who posted the different calorie counts. Curiosity how the calorie count changes if you ferment since everyone claims they save bank when they do FF.

What do you mean by flock raiser and layers not having the same caloric count by weight? Are you meaning that one pound of flock raiser is not the same as one pound of layer?
If both of these type feeds were both say 18% protein levels (depending on the other vitamins/mineral levels) in my eyes they are pretty much the same thing...right?

I ferment and I do NOT save bank.

I randomly choose two feeds from the same name brand.
One is a layer and the other is an all flock. Are these not very close to the same thing? (other than the calcium levels)

(This has nothing to do with this thread but let it be known that I just read for the first time on this particular all flock feed back that it is NOT recommended for birds under 6 weeks of age. I had assumed that all flock was for all birds and all ages. Must read each feed bag. All name brands are very different. )

I am somewhat confused by this thread since this is well known and can be googled.

There are multiple ways to compute percentage of protein/fat/carbohydrates but only a few are used by any feed manufacturer:
1) As a percentage of DRY matter
2) As a percentage of "As Fed" by weight
2) As a percentage of calories

For 1) this is done by weight of dry matter. To do this, you must know the moisture content of the item. Once you know the percentage of moisture you can calculate the total dry matter and use this to determine percentages of protein/fat/carbohydrate by weight. This is what is meant when people say that you need X grams of protein per day or on food labels that indicate values on a dry matter basis.

For 2) this is done by providing percentages of total weight including moisture. This is typically what is seen on food labels that read "As fed". Because this includes water weight you cannot use this value to compare disparate types of foods (think dry dog kibble vs. raw meat or raw egg vs dry grains) without converting to method 1 or method 2.

For 3) this is done via total calories vs calories generated by protein/fat/carbohydrate. Calculating this way will always show fat as much higher than carbohydrates & protein (4 calories per g) as fat (9 calories per g) has more than 2x the number of calories for the same weight. This is what you see when food labels tell you that an item is X% of a 2000 calorie daily diet.

You can only compare values computed via the same method and sometimes you need to do some sleuthing to determine what method is used on a feed label. It does not matter which method you use as long as you are consistent and don't compare values computed by different methods or use method 2 to compare foods with different moisture content.

Here are a couple of links that have some background on computing protein levels in dog food (similar concept - you can ignore the raw vs kibble debate and focus on the math):

YEs! Thanks.
There is a lot of talk like this in the book but I haven't deciphered it all to elementary level English...yet.

I am stuck on this book because in all my research for my feed comparison chart I noticed this book sited on several feed manufacturers sites.

Are you suggesting that what is confusing some of us is that we are trying to compare dry foods with say a wet egg?

Google knows everything but the user of Google must decipher what is good info and what is not.
It is not always easy to trust bloggers...IMO.

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.

Not all protein is necessarily absorbed 100 percent of the time.
What REALLY is bothering you?
