Environmental Impacts of Products of Animal Origin


Livestock production not only leads to high greenhouse gas emissions, but also to the pollution of ecosystems through the nutrients nitrogen and phosphorus, or to high land use with major implications for biodiversity. Consequently, the ongoing improvement of these systems is a major concern. In this context, both the emissions on the farm as well as those generated by purchased feed and livestock are of importance. Feed conversion, composition of the ration and the way in which feed is produced as well as the system’s design (e.g. combined dairy and meat production vs. suckler cow production) all greatly influence the environmental impacts of the animal production systems.
