Calculating Protein Percentages of Eggs and Peas

[EggSighted4Life]

It is easy
Let say that the %of protein is:
Feed 20%
Egg 18%
Peas 15%
In the first example
Take the % of each and make an average it is because you have taken 100 gr of each.
But if you take different amounts let say
100 grams of feed 50 grams of egg and 180 gr of peas then you should do this:
20%=0.2
100 gr of feed x 0.2= 20 gr of protein
18%=0.18
50 gr of egg x0.18=9 gr of protein
15%=0.15
180 gr of peas x0.15= 27 gr protein
Then
(Total whigt of protein in grams/ total whigt )x100= the % of protein in the mix
(20+9+27/100+50+180=56/330=0.169
0.169x100=16.9% protein in the mix.

Yes, you figured it out by weight... Now if you multiply by how many calories you would get the feed conversion factor or its' protein % of calories.... again I contend that chickens do not eat by weight but by ENERGY (caloric) value.

Good link!
So that eggs are 13% protein.

No they are 13% of the recommended protein daily allowance of a 2000 calorie diet...

Uhhh... but how the body processes the food should be taken into account too. I mean every food is processed by the body differently. Some are easier some are more difficult. I would think that the nutrients would be more easily processed by the body in a less human processed form. egg vs. Dry feed.

The sugar in fruit is not as bad for you as processed cane sugar. Because your body processes it differently.

No they are 13% of the recommended protein daily allowance of a 2000 calorie diet...

If a 50 gram egg contains 6.5 grams of protein that is 13%, right?

6.5 / 50 x 100 = 13%

My diabetes begs to differ.

But that did get me wondering last night... if we use a banana for example that has say 100 calories. Does the nutritional value change with ripeness? It sure taste sweeter when ripe... but the caloric value doesn't change (does it) so something inside must be... I can't help but wonder how that effects so many food products and their nutrients.

But the daily value percent is based on it's value inside a specified caloric content NOT the amount that is in the product.

I'm not understanding what you are saying.
Here are peas
This is amounts for one cup of

raw peas:

1 cup of raw peas has 8 grams of protein.

1 cup of raw peas has 8 grams of protein.

How much does one cup weigh?

 

[EggSighted4Life]

If a 50 gram egg contains 6.5 grams of protein that is 13%, right?

6.5 / 50 x 100 = 13%

By weight yes.

By calories... 6.5 grams x 4 calories (for protein)= 26 calories/50 x 100= 52% by caloric content.

So is it weight or energy that our birds are eating to meet? Can we agree on that so we can decide which IS the more relevant matter when it comes to feeding eggs to our birds... at 12% protein, that wouldn't be worth it to me.

@Percheron chick does seem to grasp what I am saying.

Hmmm... so then the glycemic load thing is not accurate? Ive never been able to fully figure it out. I just figured there must be something to it.
