How would you define "nutrition"?

Why is nutrition important in today's livestock production?

What are the six major classes of nutrients?

Crude protein (CP) is determined by the Kjeldahl method. It analyzes the content of ____________ in the diet. a. Nitrogen b. Minerals c. Protein d. Water

Ether extract is determined by extracting the dried sample in organic solvent (ether). It represents which component of the feed sample?

As the dry matter content of a feed increases, the moisture content a. Increases b. Decreases c. Remains the same

Among the different proximate analyses, this is a calculated value a. Dry matter b. Crude protein c. Crude fiber d. Nitrogen free extract

This test measures the inorganic component of feed in proximate analysis a. Ether extract b. Moisture c. Crude fiber d. Ash

A researcher conducted nitrogen (N) analysis on an unknown feed sample and was found to be \(7.0 \mathrm{~g}\). The crude protein (g) content of the feed sample is calculated as follows: a. \(\quad 7.0+6.25\) b. \(7.0-6.25\) c. \(7.0 / 6.25\) d. \(7.0 \times 6.25\)

Select the component of forage that is NOT a part of neutral detergent fiber (NDF) a. Starch b. Hemicellulose c. Lignin d. Cellulose

Differentiate between neutral detergent fiber (NDF) and acid detergent fiber (ADF).
