Calculating Protein Percentages of Eggs and Peas

[R2elk]

feeding eggs to our birds... at 12% protein, that wouldn't be worth it to me.

Feeding hard boiled eggs is not about increasing the protein level being fed, it is about increasing the quality of protein being fed.

I don't have any problem believing that hard boiled eggs are 12% protein simply based on the fact that the albumen is all protein but it is also 88% water. When you subtract out the water, that leaves 12% protein.

Late to the thread... I have been wondering this for a while seeing the protein values in eggs from the sites I've looked at...lol. While I agree that protein content is important; from my experience feeding raw eggs, I feel eggs help cover more than just protein content but essential amino acids from an animal source and in the ratios that are being used from the hen given back to them. The originals did eat feathers and they would peck a bit at the very beginning. However, now there are zero issues with feather eating, aggression towards birds with visible blood and they won't peck or eat a carcass, even with exceeding stocking limits and being under stress with the guineas.

Eggs
One large whole egg contains 6.28 grams of protein, containing all nine essential amino acids: histidine, isoleucine, leucine, lycine, methionine, phenylalanine, threonine, tryptophan and valine. Of the four nonessential amino acids, eggs have alanine, aspartic acid and glutamic acid. The semi-essential amino acids arginine, cysteine, glycine, proline, serine and tyrosine are also present in eggs. In all, eggs have 18 amino acids. The yolk and white each contain the same 18 amino acids; to avoid the cholesterol in yolks, use only the whites, according to the U.S. Department of Agriculture Nutrient Database.

Peas, like any grain, have average values and weights when it comes to stats. However, feed companies get samples in and test them for protein and use those values to base their mixes on in addition to what's been said previously on this thread.

http://www.rayglen.com/crop-bushel-weights/
For example, wheat's base weight per bushel is 60. The wheat I'm currently using for the chickens is heavy with a 69 lbs/bushel weight and it has a high protein value over 13.5...very nice with low/no mycotoxins.

Each field and even each load of grain can have a different protein value. Protein values tend to increase when the grain gets stressed; hot weather, lack of rain etc. It can be influenced by the timing of fertilizers etc as well. Processed feed will have the values listed...but if sourcing from a farmer, just know the protein values can differ. They should be able to provide you with it's protein value if they've gotten it tested at a grain company. Here, testing is done free to determine the quality and thus the price point offered by the grain company.

Not every field pea is equal. I requested to grow field peas this year and we've put in 70 acres for the chickens and the sheep. Our very helpful crop specialist called their animal nutritionist to locate appropriate varieties. I wanted a variety with low trypsin-inhibitor values that averages a higher protein value and is resistant to lodging. Low trypsin inhibitor values are important when looking at peas. In general, peas are one of the safer feeds. Grains high in trypsin inhibitors like soybeans is why these feeds can't be fed raw to livestock and must be heat treated for livestock. I can get complex...lol.

We've used feed peas in a blend for our breeding ewes and lambs. Peas work very well for finishing hogs and lambs. They give a great flavour to the meat. However, this is the first time we'll be incorporating peas for feed for the chickens. We used peas specifically as a smaller percentage of my feed ration for keeping good weight on the ewes but not high enough to reduce milk production. We consider it a fairly rich animal feed. I'm hoping our peas turn out.

Since all the feedstuff analysis charts Ive seen and used has the protein percentage of feedstuff (not the grams of proteins) it make sense to me to use percentage of protein for calculating the total feed analysis.

And those feed stuffs are dry... are they not?

No I slept through ALL the science, history, and English classes.

Being raised by addicts who lied through their teeth made me search for the CORE truth in everything. Though I will be real, sometimes the mind spinning a thousand times a minute trying to process all these thoughts and not miss a SINGLE detail... can be VERY debilitating. But then there is chicken therapy! I love math... It's very black and white. But word problems were never easy.

I spread a lot of so called advice on this forum and don't wish to be it to be inaccurate. And my brain has seriously done this exact problem hundreds of time since last year. Nutrition happens to be one of those things that I think is seriously key. I was shocked to see people saying feed eggs for protein when my brain looked at the grams of egg and protein verses fat and said HUH?!

But I do believe we have hit the nail on the head...

In WET calculations... using calories to get your ration will give you the correct percentage.

If DRY, it can be done by weight... accurately! But I bet the caloric value is still the same?

That 50g egg is not it's dry weight, so calculations based on dry weight don't apply.
Likewise, those green peas; were they dried peas, or fresh?
Must be consistant!

Did you see Benny's post about drying it out?

Lol you crack me up.

I'm not laughing at you.
I too am spinning the wheels trying to get a better grasp here.

But the Albumin is not 100% of the egg and the yolk still contain protein according to the link you provided.

It also agrees that an average egg contain 6 to 7 grams of protein which would still be 24- 28 calories of the total egg value.

Your link does show that protein digestibility in eggs goes up if they are cooked. That's fantastic to know! But cooking does not remove 100% of the water content that is left for the body to do (maybe the colon or intestine?).

Thank you so much for a lively and valid conversation!

I also agree with @Wickedchicken6 that when feeding eggs back to birds it is not just about the protein levels/percentages.
Wick...can you stop working so much so you can post helpful info more often?

I'm sensing a topic of the week brewing here!

No not all are dry, example molasses, potato, milk, distillers grain have both a wet and dry analysis. The protein percentage of a dry egg with all water extracted (powdered egg) would be closer to 52.1% protein.

Will definitely agree with this and recently think I notice it heavily impact my hatch rate when I recently fed eggs will often see 100% hatch rate... Maybe part of my new routine... in which I will calculate fresh eggs to have a 34% protein value.
