Feed composition and requirement tables are reported on a $100\%$ dry matter basis. Reporting on a DM basis

provides a common reference point to compare feeds' nutrient content.

If a feed sample weighs $107$ g as$-$fed and weighs $91\mathrm{.}7$ g after drying $24$ h at $100$ C $,$ what is the dry matter

$(\%)$ of the as$-$fed feed sample?

The following information was determined from analysis of a feed sample:

Feed sample weight

Sample weight after drying $24$ h at $100$ C

Dried fat free residue following ether extraction $($of #$2)($dry weight$)$

Dry residue after boiled in acid then alkali

Residue after ignition $($of #$4)$ at $600$C

$0\mathrm{.}32$ g

Nitrogen content of $2\mathrm{.}0$ g of dry feed sample

Residue of $2\mathrm{.}00$ g dry feed sample after ignition at $600$ C

$0\mathrm{.}12g$

$0\mathrm{.}25$ g
