Now I know how to figure out the DM of protien and the usual stuff. Which all come out to percentages. But I am having a hard time figuring out DM for vitamins and minerals

This is from http://www.serve.com/BatonRouge/nrc1.htm

" 100 gr raw turkey liver contain ("as fed"):

70.5 gr water

2.48 mg Zinc

0.502 mg Copper

72.4 mcg Selenium

What would these values look like on a "dry matter" basis? The "dry matter" content of the raw turkey liver is obviously 29,5% (100 - 70,5). Results:

100 gr raw turkey liver contain (on a "dry matter" basis):

Zinc = 8.4 mg (2,48 divided by 29,5 multiplied by

Copper = 1.70 mg (0,502 divided by 29,5 multiplied by

Selenium = 245.42 mcg (72,4 divided by 29,5 multiplied by

Is the 100 in bold the total amount of liver we started with (100g) or is the 100 pertaining to a percentage?
