Out-wintering pads (OWPs) are a cattle-housing system in which a layer of timber residue (often ~50 mm woodchips is placed over an artificially drained surface to control solid and liquid excreta from animal confinement.Smith, K. 2005. Final Report: Survey of Woodchip Corrals and Stand-off Pads in England and Wales: Construction, Operation and Management Practices, and Potential. Wolverhampton, UK: Environmental Protection Agency, ADAS In some climates such as the United Kingdom and Ireland, OWPs allow livestock to be housed outdoors over winter.
“Spent” timber residues (STRs, timber residues soiled with animal excreta) can be applied to land as a source of organic matter and nutrients.Augustenborg, C.A.; O.T. Carton; R.P.O. Schulte; and I.H. Suffet(2007) "Response of silage yield to land application of out-wintering pad effluent in Ireland", Agricultural Water Management, 95(4)367-374.)Augustenborg, C.A.; O.T. Carton; R.P.O.
