2. 2 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.

4. 4 SELECTION OF CROPS Pasture grass ,Elephant grass Gauingrass ,Sudangrass, Fodder grass ,Leucaene. Rice straw,Wheat straw, Soyabean chaff , Corn ,Sorghum.

5. 5 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).

6. 6 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.

8. 8 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.

9. 9 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
