Calculating Protein Percentages of Eggs and Peas

[casportpony]

@EggSighted4Life, you're a great sport!

Question... so if you mix 100 grams of 20% poultry feed, 100 grams of frozen peas, and 100 grams of boiled egg, what is the percentage of protein of the 300 grams of stuff?

Eggs have 13% Protein. That's less than Grower-Finisher feed 15%, by weight.
That's why restaurants offer Sausage and Bacon with eggs. .
Field pea grain is 25% Crude Protein vs 46% Crude Protein for Soybean meal, by weight.
Of course grains and meal are mostly dry. Eggs are not. GC

What is field pea grain? Is that a dried pea?

Field peas are sometimes used in Soy free poultry feeds.
Scratch and Peck use whole field peas in some or most of their feeds. GC

So I can see that in the field peas you mentioned that the protein is quite high. Thanks for telling us about them.

Thank you!

Let me start up the conversation since I was part of the hijacking crew.

I say % is based on caloric value and NOT weight when we are talking in regards to feeding and energy usage.

Based on this, an egg has 70 calories of which 45 will belong to fat and 24 will belong to protein... Making 45/70= 64% fat and 24/70=34% protein. For a total of 97% seems to make sense to me since eggs are essentially fat and protein with some vitamins and minerals.

My first go around in my overthinking brain tried to go with total GRAMS and do weight... but the numbers SIMPLY do NOT add up... and I believe our chooks eat to meet their energy need and not a certain volume. By weight... 6/50 grams would be 12% protein and 5/50 grams would be 10% fat... That's ONLY 22% of the total egg value and I JUST don't buy it.

The first time I tried by weight, yes... I though 12% protein is WAY too low for someone to suggest it as a "good source". Now I believe I have finally worked out the truth. But I'm not at all cocky and here to learn! I have thought about starting this VERY thread last year.

Can't wait to see the answers!

It is by weight .

My feed is Non GMO and doesn't have soy or corn in it does have field peas.

Ask and you shall receive.
Raw egg (no shell)
52.1 percent protein
41.1 percent fat
5919 caloric energy (kcal/kg)

Looking at these numbers and seeing the high amount of kcal I would say it would make a better treat rather than a feedstuff. High amount of kcal meens your bird eats less feed and unless you copusate for that your going to experience nutritional deficiencies.

What link is that from?
