1. Importance of fodder conservation
The importance of fodder conservation is to capture the nutrients in grass in a storable form to make them available as a forage feed in the dry season. Feed can be conserved as hay or silage.

4 Silage making – sweetpotato vines
To make an improved plastic tube silo you will need:
4 cm PVC drainage pipe
2.5 m of 1000 gauge silage tubing
2.3 m of flexible rubber tubing
One 4 cm plastic tap
7 m of sisal twine
3 wooden poles (can be cut locally), at least 1.2 m in length and 5 cm in diameter
Fabricated drum
10 kg of molasses
30 liters of water
375 kg of fresh vines and 175 kg of fresh storage roots or Napier grass or similar to make 500 kg silage
2. Hay making
Timing: harvest hay at early flowering
Mowing
Tedding
Drying : let the grass dry for 3 days
Raking: rake after 2 days to allow for even drying.
Baling: you can use a manual hay bailer
Storing: should be store in a cool dry place away from rodent and termites as well as leaking roofs
Stages
Proper wilting needs to be done for sweetpotato vines
Compaction of the vines is necessary to expel as much air as possible. Compact as you add molasses every 30 cm.
Store the silage under a shade and place some weight on top of it.
3. Determining good silage quality
Well-prepared silage is bright or light yellow-green in colour, has a strong smell similar to that of fermented milk and a firm texture.
Poor quality silage tends to smell similar to rancid butter or ammonia. 1 2

Silage can also be made from maize stalks at ‘milk stage’ and Napier grass
(1 m tall and chopped to 2 cm)
