WHAT IS SILAGE?
 Silage is defined as a material
produced by controlled fermantation
of crops under anaerobic condition.
 Green fodder can be conserved
assilage after fermantation.

3. 3
 Fodder crop rich in carbohydrate are incubated
for 45-50 days under anerobic condition .
 Sugar present in fodder gets cnverted to lactic
acid that acts as preservative.
 In anerobic condition is not mantained well
during silage production then butyric acid is
produced and the quality of silage is affected
negatively.
 Properly produced silage can be stored for two
years.

SELECTION OF CROPS
 Pasture grass ,Elephant grass
Gauingrass ,Sudangrass,
Fodder grass ,Leucaene.
 Rice straw,Wheat straw,
Soyabean chaff , Corn ,Sorghum.

PROCEDURE
1-Harvesting of fodder at proper stage (before they fully
matured).
2-Moisture 65%-7% ideal.
3-Chopping (1-3cm).
4-Spread chopped fodder to make a bed of 2 feet height in
silo-pit.
5-Compact fodder as tightly as possible by using tractor
/hand roller.
6- Sprinkle mollases solution over it.
7-Add bran and other silage additive (microbial culture).

8-Repeat the step 4-7at least 6-10 times till the silo pit is
completly filled up.
9-Seal the pit airtight plastic cover or clay plate.
10-Press plastic cover.
11-Maintain sealing For 45 days.
12-In the process,lactic acid upto a conc. of 1% is formed
,butyric,acetic and propionic acids are formed trace
amount of alcohal may be formed .
13-After 45 days highly palatable cattle food is formed
inside the pit.

MICROBE USED IN SILAGE
PRODUCTION
 Lactobacillus is the main heterofermentative lactic
bacteria used in silage inoculants.
 These bacteria can convert lactic acid to acetic acid and
other products.
 Acetic acid is a good inhibitor of the yeasts and molds
that cause heating and spoilage of silage.

SIGNIFICANCE OF SILAGE
 A Cheap subtitute for fodder at the time of fodder
shortage
 Silage makes the fodder more digestible
 Animals get nutritious feed the whole year
 Improves animal performance
 Highly palatable
 lowers harvest losses
 increase forage quality
 prevent spoilage of fodder
