Theory:

Storage of the harvested grains is an important task in agriculture.
 
The harvested grains may some times need to be kept for longer duration of time. In such cases, the food grains should be protected from moisture, insects, rats and microorganisms.
 
Drying:
Freshly harvested grains (seeds) have more moisture. So they need to be are stored after drying in sun light, if not they may get spoilt or attacked by micro organisms like fungi, making them unfit for use or for germination. Drying prevents the attack by insect pests, bacteria and fungi.

Packing for storage:
Before packing the grains to store they need a treatment of preservative.
Dried neem leaves are used as a preservative for storing food grains at home. For storing large quantities of grains in big godowns, specific chemical treatments with preservatives are done to protect them from pests and microorganisms.
After this treatment farmers use jute bags or metallic bins to store grains. Large scale storage of grains is done in silos and granaries to protect them from pests like rats and insects.

Animal husbandry:
Similarly, animals reared  on a large scale for instance, cows and buffalos for milk and milk products, is called animal husbandry. These animals need to be feed, sheltered and taken care properly.
