No-wash-pigs-technology is a very easy and economical way to manage small-scale piggeries. This technology is simple, not laborious, and can be adopted by household who want to raise pigs in small-scale. There’s no need to wash pigpens more often to keep the neighbor from complaining petid odor.
In this technology, pigpen is made of bamboo and nipa and its concrete flooring is slightly inclined to force water and waste to flow down the drainage. The floor is also stocked with 6-inch bedding which contained equal amount of river or beach sand, fresh rice hulls, and carbonized rice hulls or rice hull charcoal.
To prevent the inhibition of mange and mites in the rice hulls, a handful of salt is added per square meter, but this is optional. A better option is to regularly add dried kakawate (Gliricidia sepium), neem (Azadirachta indica), and ipil-ipil (Leucaena leucocephala) leaves for these help fasten the processing of the bedding mix into organic fertilizer when it is removed from the pen at the end of the cycle.
Since the bedding mix absorbs foul odor, hog raisers don’t need to wash their pigs everyday. All they need to do is feed the pigs and spray the bedding with a probiotic solution weekly. The probiotic solution is made of dissolving two cups of concentrated indigenous microorganisms (IMO), which contains beneficial microorganisms like yeast, lactobacilli and mold, per 15 liters of water.
The bedding is remove immediately after each cycle and allowed to age for two to three weeks before using it as an organic fertilizer. During the aging period, microorganisms in the bedding speed up the decomposition process, but the bedding will degrade faster if it is feed to earthworms.
