A house is the most important consideration for new pig project. It is
unfortunate that many new pig farmers do not consult well on pig houses before embarking
on construction. It is not enough to copy a pig house you have come across. It’s good to understand that pig houses are constructed according to how pigs behave. The same reason that zero-grazing units are built in a particular way to make cleaning easier and have the cows comfortable.
So much as you and I , pigs need a dry bed and protection from extreme temperature and sunburn. Minimum requirements apply for space, fresh air, and hygiene, access to feed and water, and accommodation. These conditions should not predispose the pigs to illness or injury.
Given that pigs like to sleep in a dark area and prefer to dung in the lighter space put this into consideration when designing and constructing the pig house.Have the dimensions as 10ft by 15ft whereby 10ft by 10ft of this is roofed while 10ft by 5ft is not roofed.
To make cleaning easier position the door into the pen in the open dunging area. This makes removal of manure easier without having to pass through the sleeping area. Also, it’s good to have a veranda between pig pens such that you have pens on the right and left side. The veranda and the pig sleeping area will be roofed while the open dunging area at the back is not roofed. There should be no door leading into the pig pens from the veranda. In the pig pens the feed trough runs along the whole length of the pen next to the veranda.
Ensure that final height of the pen partitions is only 31/2ft and the workman should be able to put feeds in the trough without having to go into the pens.
The whole pig pens floor should slope towards the dunging area.
Your water trough should be at the dunging area. Any water spilling from the water trough should drain out together with any urine. There should be a cemented drainage outside the pig pen to drain away from the pig house. Make water troughs in such a way that pigs are not able to sleep in the trough and spill out the water. Automatic drinking nipples help avoid this as they ensure that pigs have access to clean drinking water adlib without any wastage.
Finally, furrowing pens need to be modified in such a way that there is a creep feed area where piglets are able to access starter meal away from the mother.
There is need to have guard rails in every farrowing house. This prevents the sow from crushing the piglets against the walls at sucking time.
NB-The minimum economical pig unit should comprise of 10 breeding sows and one boar.
For such 20 pens will be needed.
