Abstract:
Conservation is a process by which a material is prepared so that it can keep for future use. Man has for long been conserving 100d to use in times of great scarcity Excess 100d which cannot be consumed immediately when fresh like beans, millet, maize etc are sun dried and stored. Cassava and sweet potato are cut into slices and sundried. In animal production when crop herbage is in excess of what can be fed to the animals, the excess feed is made into silage or hay to conserve it.
