Abstract

Two technologies were evaluated for daily manure removal in shallow, sloped pits in swine finishing facilities. The criteria included cleaning ability, initial cost, and water usage. One system selected for the trial was mechanical and one was liquid-based. Preliminary results of the scraper system have shown clean pit floor and side walls. The frequency of scraping has been reduced to several times per day and twice after a weekend. Challenges of the system include cleaning the front 0.45 m (18”) along the wall and using water to assist the drainage of manure. Results of the tip tank have shown a 4 gallon per pig recycle water usage per day. Flushability of the solids and development of sufficient head were factors in this 3 design. Both systems were automated to lessen human intervention and designed to allow the recycle pumps to be shut down at night.
