Document Summary
Divide the nutrient content by the fractional percent dry matter: example: an all purpose complete feed contains 16% crude protein on an as fed basis. After drying over night in an oven, you find that it also contains 92% dm: 16 / . 92 = 17. 39% cp when expressed on a dm basis. General rules of thumb: when going from as fed to dry matter basis, the number will always become larger, this is because you"re removing its water content from the equation which concentrates the dry nutrient content. General rule of thumb: when going from a dry matter to an as fed basis the number will always become smaller, this is because you"re now including its water content, which dilutes the dry nutrient content. 20 lbs feed a x . 12 = 2. 40 lbs water. 20 lbs feed a x . 88 = 17. 60 lbs dm.
