No smell pig pen is made in such a way that the floor/ bed mimics a natural forest which digests the pig excreta very first anaerobically to prevent the pen from smelling. The bed that helps prevent the pig pen from smelling is removed after about 7 months, used as a fertilizer and replaced with a new one.
IMO pig pen
To construct a no smell pig pen, determine the size and number of the pens that you want to construct.
After constructing the foundation, excavate the floor to about 3 feet deep and add a log of wood in the made ditch to about 1 foot and this where the IMO would sit.
Fill the hole with dry grass to a depth of 1 foot followed by 1 foot of saw dust and now the pigsty is ready for use.
IMO pigpen advantages
A no smell pig peen is less tedious to maintain and doesn’t require much labor.
It s easy to construct and it eliminates odor.
Makes the pigs take more water because of the heating of the floor and this in turn makes the pigs grow fat.
