CYCLICAL LIVESTOCK FARMING METHOD FOR NO-TILLAGE ORGANIC CULTIVATION BY PASTURING ANTIBIOTICS-FREE PIG

摘要

PROBLEM TO BE SOLVED: To provide a cyclical livestock farming method solving the following problems that conventional cultivation requires breaking up farmland with hands or a machine, but tillage-free cultivation results in having difficulty in sowing seeds in the soil of the farmland and being annoyed with weeds; also the conventional cultivation requires use of fertilizer and agricultural chemicals for weed control; and the fertilizer is produced by using substance containing antibiotics taken by the livestock and discharged as excrement.;SOLUTION: The cyclical livestock farming method includes pasturing pigs in a surrounded farmland to breed them so as to allow the pigs to bite weeds and their roots and thereby make the weeds run out. The pigs dig up the soil with their noses in order to bite the roots, so that the soil is cultivated without bothering human hands. Microbial material is given to the pigs without using any chemicals such as antibacterial substance as feed for the pigs to be pastured and bred, so that the discharged feces and urine serve as compost and further as an organic fertilizer for the farmland. After shipping the pigs from the farmland, the seeds of farm crops are sowed on the farmland to make organic cultivation without using any fertilizer. The harvested farm crops are shipped as commercial products having additional value because of being completely chemical free. The farm crops out of substandard in shipping can be used as chemical-free fertilizer for the pigs.;COPYRIGHT: (C)2010,JPO&INPIT
