Abstract: A system for housing animals in animal husbandry, particularly for raising pigs comprises a separately transportable container (15) manufactured from metal walls (20-24) which is individually supplied with a fan ventilation system (37), a bottom manure container and a feed supply (60). The animals can be transported in the container (15) and maintained in the container (15). The container can be located in rows of the container along a central alleyway (10) through which the animals can be moved and which supplies the necessary facilities. In one use of the system, the animals can be transported to a position adjacent to but spaced from a new location and maintained in quarantine until the possibility of disease is passed. In a further process for the Isowean system of raising pigs, the nursery stage between the farrowing stage and the finisher stage is carried out in the containment vessel thus avoiding additional movement of the animals which is stressful for the animals.

Abstract: A method of treating waste materials such as city or animal sewage which may contain toxic chemicals includes supplying the waste materials in slurry form using a dispensing machine in the field to a fibrous crop material so that the waste materials, water and toxic chemicals are taken up by the fibrous materials in the plant to avoid toxic materials collecting in the soil. The amount of nutrients in the waste material including phosphorous and nitrogen are measured. The volume of materials supplied to the plant is controlled upon the phosphorous level. The amount of nitrogen can be supplemented on the go from a separate tank on the dispensing machine.
