What happens to the total amount of a sample when you convert from DM to AF?

100

When converting from DM to AF, what happens to nutrient percentage?

100

When converting from AF to DM, what happens to nutrient percentage?

Increases (Removing water=concentrated)

100

What happens to the total weight of a sample when converting from AF to DM?

Decreases (Removing water=removing weight)

2. A gang

3. A rave

An unkindness

200

If a feed is 40% DM, how much moisture does it have?

100-40= 60% moisture

200

How do you remove water from a feed sample?

Dry at 60 C for 72 hours

200

Organic matter (OM)= DM - _____

Ash (ash is inorganic, can not be burned)

200

How do you remove organic matter from a feed sample?

Burn at 500 C (you are left with ash which is inorganic)

200

What is a dot over the letter i and j called?

1. a title

2. a tittle

3. a tattle

a tittle

300

If a feed weighs 100 grams on an AF basis and is 60% moisture. How much does it weigh on a DM basis?

100-60= 40% DM

100 x .4= 40 grams DM

300

What happens to the individual nutrient amounts when converting from DM to AF?

STAY THE SAME (No matter which way you flip it)

300
If a feed sample contains 100 grams of DM and 15 grams of ash. How much organic matter does the sample contain?

100- 15= 85 grams of OM

300

100 grams of DM was burned at 500 C. The weight of the remaining materials was 10 grams. What percentage of the DM was ash?

(10/100) x 100= 10%

300

Sugars

Starches

Proteins

Fats

500

The dry matter (70 grams) was dissolved in a neutral detergent extraction solution. 15 grams of dry matter was NOT dissolved in the solution. Calculate NDF content as a % of DM?

(15/70) x 100= 21.4% NDF DM

500

What is the approximate measure of true proteins in the diet?

crude protein

(remember NPN are all nitrogenous components in feed that are NOT true proteins)

500

How do you calculate crude protein?

Solve: 55 grams of DM contained 4.0 grams of nitrogen. Calculate the amount of CP in that feed sample.

CP= Total N in feed x 6.25

(Why 6.25? 16% of CP is nitrogen)

4.0g x 6.25= 25 grams CP

500

A feed sample contains 100 grams of DM. The ether extracted 4.0 grams. What is the crude fat % DM?

(4.0/100) x 100= 4% DM
500

1. Donkeys

2. Lions

3. Camels
