Two examples of application of ecological modeling to agricultural production: Extensive livestock farming and overyielding in grassland mixtures

摘要

Livestock production plays an important role in guaranteeing food security worldwide and has an important contribution to the economy of many countries. Precision livestock production (PLP), or the manipulation of livestock activity taking into account the different components of agroecosystems pastures, cattle and pasture-cattle interactions-, has acquired growing importance in recent years to optimize productivity. Regarding the pasture component, multi-species pasture mixtures are commonly used worldwide to increase primary productivity and thereby secondary productivity.
