Calculating Protein Percentages of Eggs and Peas

[Kiki]

So when Mazuri says 20% protein I would read it as if I fed 100 grams of this feed I would be feeding ~20 grams protein. But is this correct? Would the 20% really mean 20 grams?

The issue with humans is that many human food labels now contain information about % of daily needs (and there are a few posts in this thread that refer to these numbers in regards to eggs). This was meant to make it easier for people to make informed decisions* but is not relevant to any discussion about chicken feeds.
I get this. But is this were some of the confusion is coming from the percentages?

(I don't really expect an answer on the second part of this because how in the world are you going to know where/why I am confused.)


So no matter what an egg has 6 grams of protein.
We can't know the percentage of the protein amount when feeding an egg to a chicken because we first must know the total of everything else the chicken needs per day?

This I can grasp... but don't get's relevance to the protein inside a fresh egg.... which is listed as both a caloric and weight. 6 grams equals 24 calories. which is 33% of the total caloric intake regardless of volume...

They have added the correct amount of protein to the mix to make it equal 20% whether you feed 1 pound or 10 pounds. It will be 20% protein.... I get that about FEED.

I think BYC needs to start a campaign to have all feed manufacturers follow Mazuri's nutritional information documentation procedures. I did ask Scratch & Peck for more info (back during your fantastic feed data spreadsheet creation) but while I did receive a polite a prompt response I didn't get any info. It would be so much easier to make decisions (and have these conversations) if there was more info available.

Mazuri is one of the leading feed producers in the world. I use a lot of there feed/s. You can't go wrong with there feed.

Well, I'm never gonna powder an egg. So for me weight doesn't matter. It will always be fed scrambled or boiled, which will lose some of it water content I'm sure. But it's protein and fat content will remain the same.

What we have established is that a chicken need about 15-22% depending on age, breed and other factors.... NEVER does the feed say your birds need X grams of protein.... everything is based on a %. What they don't tell us is that % caloric or by weight. Now the weight will equal more or less calories accordingly. But ANY animal needs to meet a certain energy (CALORIE) load.

I had so much fun yesterday! Today I just wanna get it figured out.


298 calories (rounded) at 20% protein would be.. 60 calories from protein. Which would equal about 15 grams per day of protein.

No because the mazuri one is based off of calories. And not a recommended daily allowance. Regardless of anyone's "need", I just wanna know the total % fat and protein content of a raw egg.

I would never feed something that provided only 20% of daily recommended allowance of protein regardless of how much I fed them of it. Our formulated feeds do MEET the daily recommendations of our birds, they just aren't listed in the same way as humans.

One serious issue I have is the high fat content. People will be feeding out eggs thinking they are doing their birds a favor... when in fact they may be overdoing it and those who ARE predisposed to certain conditions like fatty liver or kidney failure may just be accentuating their issue. Most our poultry feed are only about 2-5% fat that I have seen. If we get it figured out the correct protein verses fat content I can move forward a lot more comfortable with any recommendation that I make.

I get that the volume of protein in a wet egg is about 12% but that is NOT where the nutritional value (as far as I can tell) comes from.

Start on page 11.
Fat/s are a whole other ball game.

Note that the charts expand if you hit the X made of arrows in the lower right corner of the chart. You can get info about different ages and even about the requirements of white vs brown egg layers (they are different!!!!!!!! - I had no idea )

You lost me.
33% of total caloric intake of what/who?

Thanks.
I have those charts.

Yes...it depends on the breed of chicken too.

It's very complicated.

Kiki what you don't understand ? Please tell and I will try to help.

Dry egg is 35% protein by calories but 47.5% protein by weight.

Is a chicken going to eat their caloric (energy) need OR a volume/weight?

Seems like a simple thing to me... If they eat to meet their energy, the calculation are based on calorie... and then wrapped into a tidy package that gives us a "weight" guideline for feeding... the must keep it as simple as possible for consumers. My dog feed always has kcal content listed.... and yes they do list their MAX moisture content also as a % of weight in the "dry" feed (since I presume moisture cannot be listed as a % of calories), in addition to fiber usually.

If I pack all fat calories which will be really dense... will my chickens then eat the same volume making for a much higher calorie content or would they simply stop once their ENERGY need is met?

Is the protein in our eggs meeting an energy need or a volume need?

Of the total calorie needed by the chicken!
Let say that a chicken needs 300 kcal/day then 33%=1/3=100 kcal.
