Representative samples of incoming raw materials must be inspected to see that
these conform to the following specifications: (9)
- Color
- Odor
- Texture
- Moisture
- Uniformity
- Temperature
- Absence of dirt, mold, sticks, metal objects, gravel and other foreign materials.
- No evidence of bird, rodent or insect contamination.
- Dry and no evidence of previously being wet.
feed must be consistent in color and texture
uniformity
feed must be reasonable particle size for the product
texture
non-sticking, no wet spots, free flowing
moisture
clean, characteristic smell, no evidence of over-cooking and undercooking as in the case of beans
odor
no evidence of heating
temperature
a mixture of all starches and sugars plus some hemicellulose and much of the lignin
Nitrogen free extract
refers to the mineral matter of the substance that remains after burning off the dry matter
ash
composed of the fibrous portions of plants, relatively low in digestibility and in nutritive value
crude fiber
includes all the portions of a feed
soluble in ether
Ether Extract (EE) or Crude Fat
measure of energy content of the feed
crude fat value
the most unstable component of feeds
fat
first analysis given on the feed tag, it is a calculation resulting from determination of the percent nitrogen (N) in the feed
crude protein
crude protein is obtained by multiplying the N content of the feed by?
6.25
