Question 52

Silage Production for Livestock Feed

Procedure for preparing grass silage:

  1. Harvest the grass crop at 60–70% moisture content.
  2. Chop the grass into short lengths (approx. 3 cm) to allow tight compaction.
  3. Pack the chopped grass into a silage clamp or wrap it tightly in multiple layers of plastic film.
  4. Add a bacterial inoculant containing lactic acid bacteria.
  5. Ensure the clamp or wrap is completely sealed to maintain a strictly anaerobic environment.

State one reason why maintaining a strictly anaerobic (oxygen-free) environment is necessary to successfully preserve the grass.
