Critical evaluation of soybean role in animal production chains based on the valorization of locally produced feedstuff.

Aim of the present article is to critically evaluate the effects of the large diffusion of soybean on the international market concerning aspects related to the evolution of soybean trade, the effects on agricultural systems where soybean cannot be cultivated, the present dependence from soybean of intensive animal farming systems and the consequences on small or medium farms applying not-intensive animal production chains. An experience under way in the Marche Region (Central Italy) will also be illustrated as an attempt to make agricultural activity both profitable and integrated within local soil and climatic characteristics.
