Answer 2

The mineral is the component that is not included in TDN estimation.

Option (c)

Explanation:

• TDN is an estimation of not all the nutrients rather the energy content in a given feed.  It is an evaluating method in the ruminant world. This is used for horses or swine.
• It includes nitrogen-free extract, crude protein, ether extract and crude fiber. The mineral is not included as a component of TDN estimation because they are less digestible. However, in order to rich the energy value provided by carbohydrates and ether extract is multiplied by 2.25.
