Is the study that deals with the nutrients and their utilisation by the animal
NUTRITION
8%= PPM
80,000
It is used when the concentration of the nutrient is very small
Parts Per Million (ppm)
Find the % of DM given the Moisture content is 19%.
81
a chemical element or compound that is essential for the normal body metabolism
NUTRIENT
98700 ppm = %
9.87 %
MILLIGRAM PER POUND (mg/lb)
A fresh forage contains:
Convert the crude protein to a Dry Matter Basis.
20%
refers to feed in its NATURAL STATE, including all moisture content.
AS-FED BASIS (WET OR FRESH BASIS)
Kg = lbs
2.45 kgs = lbs
5.3998 lbs
It is the most basic and widely used form of nutrient expression
PERCENTAGE (%)
A feed sample contains:
Convert both nutrients to an Air-Dry Basis.
CP = 18.00%
EE = 6.75%
Most commercial feeds and forages are considered to be
AIR-DRY BASIS
pmm = mg/lb
3.5 ppm = mg/lb
1.5876
the overall composition or mix of feeds an animal eats.
DIET-
A hay sample contains:
Express both nutrients on an As-fed Basis.
CF = 28.16%
EE = 4.40%
represents everything contained in a feed sample except water; this includes protein, fiber, fat, minerals, etc.

the daily food allowance
RATION
A commercial poultry feed has the following proximate composition:
Question:
Compute the total carbohydrate content of the feed.
Carbohydrates = NFE + CF
= 45 + 8
