Description: In Canada, dairy herds are generally housed over the winter months and in many instances on a year-round basis. Faeces and urine are therefore deposited within a confined area over an extended period of time. The management of this manure, from collection to storage and later spreading on the land, represents both an unpleasant chore and a considerable investment in labor, equipment and structures on the part of a dairy farmer. Major emphasis is generally placed on the single criterion of net annual cost in providing farmers with information on which to select a dairy waste management system. In particular, many studies have been confined to the use of optimization techniques which determine only the least cost complete system. However, such economic information is just a portion of the full set of information required to make a rational decision at the farm management level. Rapidly rising energy costs and potential shortages of fossil fuels, availability of labor, and capital for initial investment present important additional concerns. Again, most farm level questions relate to the upgrading of portions of an existing system. Information is therefore required not only for complete systems but, more importantly, for alternate subsystems within an otherwise fixed system.
