- EXTENSIVE SYSTEM
- The condition of the environment closely resembles the natural habit of snails compared to other systems.
- Low labour and low general management input i.e. inexpensive to maintain
- The farmer needs not purchase feed because it is already available in the snailery.
- There is no restriction on the movement of the snails.
DISADVANTAGES OF EXTENSIVE SYSTEM
- Little control over the performance of snails
- It requires a lot of land compared to others of production.
- Record keeping is difficult.
- Poor disease management.
- The snails are exposed to predators’ attacked (e.g. soldier ants)
- Mortality rate could be higher than other systems.
- Semi-Intensive System
- The system is like the extensive system except that the snails are supplied
- with feeds besides what is grown in the snailery
- INTENSIVE SYSTEM
In the intensive System, the Snails are only fed with feeds brought to the snailery.
- It is good for backyard or commercials farming.
- Record on performance of the snails can be kept.
- There is proper control over disease and predators
- The management practices are simple.
- It can be practiced both in urban and rural area.
- The growth rate could be influenced by introducing formulated ration.
- The mortality rate is low.
The snails can be stolen at once because the confinement which is very difficult in extensive system because the snails are scattered
