Calculating Protein Percentages of Eggs and Peas

[Akrnaf2]

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. )

Not at all, the main source for calories are carbohydrate and fats and less proteins. So if one pound of feed have 18% of protein and 60% carbohydrate and 22% fats it doesn't have the same calories as a pound of feed that have 18% protein and 75% carbohydrate 7%of fats. Because 1 gram fat is almost
9 kilocalorie vers 4-5 kcal for carbohydrate.

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

That as well as confusing percentage based on calories with percentage by dry weight or "as fed." People are finding information about nutrient contents on various sites but not paying attention to what method those sites are using when comparing them to information on other sites.

If we just stick with eggs, they are considered a high protein food for good reason. You cannot compare egg nutrient percentages by weight directly with dry chicken feed because moisture content is so different. You also can't compare them using sites that tell you how much protein an egg provides as a % of a human's daily caloric intake since a) that is a different species and b) the numbers on the labels of chicken feed are either given as % of dry matter or % of "As Fed" (i.e. including moisture). On a dry matter basis eggs are much higher in protein than chicken feed. I believe that they are something like 45-50% protein on a dry matter basis while chicken layer feed is typically something like 16-20% depending on how much moisture you estimate*.

*I am still not sure how most chicken feeds are actually labelled (as fed or by dry weight). Even Mazuri that seems to have the most complete nutrition information does not indicate which (dog foods often specify). Regardless, the moisture content is LOW so the numbers on the bag will be close to dry weight.

Yes they do look the same other than calcium.

The layer I usually see is 16% protein and 4% calcium and the flock raiser I use is 20% protein with about 1.5% (might have to pull the tag). When my birds eat less flock raiser by weight than someone who feeds layer... doesn't actually even out exactly because they are eating their oyster shell on the side verses the person feeding it mixed in.

Again I ask.. so many of your guys' links and the book kiki is using say that they eat to meet their "energy" needs... not to fill the volume of their stomach.

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!

Not at all what?

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??

Again I ask.. so many of your guys' links and the book kiki is using say that they eat to meet their "energy" needs... not to fill the volume of their stomach.

So...if there energy need is met by eating approx. .25 lbs of feed per day.
How would I count/figure out how many calories that .25 pound of feed equals?

 

[EggSighted4Life]

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

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%.

But offcorse! Do you grasps the meeting of percentage?
Water has 0 calories but it have whigt! Because of that it DOESN'T influence the calories yield but IT SURE INFLUENCE THE PERCENTAGE!

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

My guess would be by calling the company and asking for a complete analysis which most don't list on the bag tags.
