自給飼料生産と土地利用型畜産

抄録

Total self sufficiency in coarse feed and an increase in self-supplied feed were set as an important policy goal of the basic plan of Japanese agricultural policy. In order to design the self-supplied feed policy system for it, it is necessary to clearly define the social meaning of enlargement of self-supplied feed production.
This dissertation is arranged from four different points of view, that is, the improvement of food self-sufficiency rate, the improvement of livestock self-sufficiency rate, management of the resource circulating system and effective land utilization. Accordingly, the shift of policy and current conditions were analyzed responding to these policy goals.
As a result, the self-supplied feed policy framework is not merely restricted to the livestock policy framework, but a regional and environmental policy to guarantee the multifunctionality of the grassland and livestock. Furthermore, this dissertation will discuss the creation of a new relationship that emphasizes the collaboration of nature and livestock; the cooperation of the field farmers and the livestock farmers is also necessary. The independence of the local government on agricultural policy will need to be seriously considered.
