Question

Wheat middlings has a dry matter concentration of 90% and a TDN concentration of 18% on an as-fed basis. What is the TDN concentration of wheat midds run feed on a dry matter basis?

Answer 1

To calculate the TDN concentration of wheat middlings on a dry matter basis, divide the as-fed TDN concentration (18%) by the dry matter concentration (90%) and multiply by 100. The result is a TDN concentration of 20% on a dry matter basis.

Step-by-step explanation:

The question is asking how to convert the Total Digestible Nutrients (TDN) concentration of wheat middlings from an as-fed basis to a dry matter basis. To do this, we use the given values: a dry matter concentration of 90% and a TDN concentration on an as-fed basis of 18%. To find the TDN concentration on a dry matter basis, we divide the TDN as-fed percentage by the dry matter percentage and then multiply by 100 to convert it to a percentage:

TDN on dry matter basis = (TDN as-fed / Dry matter concentration) * 100

TDN on dry matter basis = (18% / 90%) * 100

TDN on dry matter basis = 20%

Therefore, the TDN concentration of wheat midds when converted to a dry matter basis is 20%.
