Crop production is, with 72%, the biggest contributor to GWP in this production system. Transport of soya has a relatively small contribution, approximately 1%.K L STEPHENB J TOLKAMPC F E TOPPJ G M HOUDIJKI KYRIAZAKISConference on Integrated Agricultural Systems: Methodologies, Modelling and ...
Farming externalities are believed to co-vary negatively, yet trade-offs have rarely been quantified systematically. Here we present data from UK and Brazilian pig production systems representative of most commercial systems across the world ranging from

Outdoor pig production systems relying on local pig breeds may cope with environmental and socio-economic challenges. They produce high quality products with added economic value and rely mainly on local feed resources. Within the European TREASURE project, we conducted the Life Cycle Assessment (LCA...
The EAA system is peculiar both from a serological and genetic point of view and because of its similarity to certain blood group systems in other mammalian species, notably the J-Oc system in cattle and the R-O system in sheep (Sprague, 1958). Each of the three species has a substance...
Mast-feeding systems once formed the mainstay of pork production across Europe, but have now largely been forgotten. One of the earliest farming practices, it allowed people to fatten pigs on an otherwise wasted resource. Mast feeding was vital in the ancient world: Rome, Saxon England and the...
The economic impact of selection for semen traits on pig production systems and potential interaction with artificial insemination (AI) technique and semen dose remains partially understood. The objectives of this study were to compare the financial indicators (gross return, net profit, cost) in a ...
It is widely assumed that the development of antibiotics had a transformative effect on livestock production by making it possible to keep larger numbers of animals in smaller spaces without them succumbing to disease. Using the health and production of UK pigs, ca. 1925-65, as a case study,...
