Calculating Protein Percentages of Eggs and Peas

[Akrnaf2]

Maybe a better question is...how many grams of protein does a chicken need per day?

Yes!
And the answer depends on age, breed, molting or not etc etc etc....

AND weather/temperature!
I know this for fact!

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?

Oh Mazuri, how many ways do I love you?

Mazuri does provide the calories content of their gamebird feed so we have someplace to start to get a ballpark number.

2625 calories/kg which is 1190.68 calories/pound which is ~297.67 calories per day.

Metabolizable energy (AMEn)
True metabolizable energy (TMEn).
Energy of maintenance (NEm)
Growth and reproduction is called the net energy for production (NEg).

Am I going to have to find a college course to take to learn this?

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.

So this 20%

is based on the 2625 c/kg which is not the same nor would it calculate the same way this percentage is calculated...because this egg is based on human needs not birds. Right?

This is partly why I made the sheet...to help me learn.
I agree this is another chicken related thing that should be the same across the board.

I doubt that this information is based on percentage of calories. Most feed labels (I am basing this on cat/dog foods) list nutrient percentages as a percentage of dry weight or a percentage of "As fed" weight. They typically provide the total calorie content but do not provide nutrient percentages based on it. 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. Calories would not enter my mind at all.

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.

*Since most people don't know how many grams of protein (or mg of iron, etc., etc.) they need per day, telling them that the product contains 3 grams of protein isn't always useful.

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.

1190.68 calories/pound which is ~297.67 calories per day.

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.
