2. Ration- A ration is the feeds offered for a
given animal during a day of 24 hours.
The feed may given at a time or in
proportion at intervals.
Balanced Ration- A balanced ration is one
that furnishes nutrients in such proportions
and amounts that it will properly nourish a
given animal for 24 hours(Morrison ,1956)

3. The ration should have highly digestible feed ingredients.
The ration should be balanced.
The ration must be palatable.
Variety of feeds included in the ration.
The ration should contain enough of mineral matter.
The ration should be fairly laxative.
The ration should be fairly bulky to satisfy the hunger.
The ration should include green fodder.
It is economical in labour and cost.

4. 4
Ration formulation depends on
The nutrient requirement of the animal.
Dry matter intake capacity of the animal.
Availability and Chemical composition of
feeds ingredients.
6. Calculate the probable DM intake .
Calculate the nutrient requirements of the
animal.
Determine the amounts of available
ingredient that must be fed to fulfill the
animal’s nutrient requirements.

Steps in Formulating a Ration
7. Total dry matter
7
Partitioning of Dry Matter(given by
Haecker )
2/3 roughage
1/3 concentrate
2/3 dry roughage or 3/4if
sufficient legume is
available
1/3 green
roughage(if green
fodder is legume it
may be restricted
to 1/4 of total
roughage ration

Concentrate and roughage Ratio(C:R ratio)
10. Some information requires for formulation of
concentrate mixture
Nutrients requirements of various
categories of livestock
Nutrient value of feed ingredients.
Availability of feed ingredients
Cost of feed ingredients.
Bio-availability of nutrient from the feed
ingredients
Non-nutrient characteristics of feeds.

Least Cost Ration- If a ration is balanced using a
combination of ingredients with the lowest
possible total cost, the resulting mixture is called
a least cost ration.
Linear programming- The technique employed to
calculate least-cost and profits maximizing rations
is called linear programming.
