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

• Assembling the internal drainage system for the silage tube
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.
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.
