Extensive livestock production and environment.Beef cattle extensive system-tradition and innovation.

The beef cattle extensive system is not a kind of innovative agricultural system, so we must taking in mind that the tradition has it place and will be the base for all kind of technical innovation. To understand the low productivity of the beef cattle extensive production, we have to show the irregularity of the mediterranic clime, the large amount of acid soils and by the way the seasonality of pasture growing. We put face at face the difficulties and risks of the weaned calves producers against the feed lots sector. At last the need of understanding by the people that are outside the extensive system for the consequences of PAC politics, what concern welfare and sustainable/durability of beef production.
