Evolution with pig BW of standardized ileal digestible (SID) lysine content in A and B feeds and in the daily feed ration according to the feeding program and in the case of females for France. 2P, 2-phase; 4P, 4-phase; DMP, 10-phase; av. req. and pop. req., curve of average pig and population requirements.

Relative contribution of the different processes (%) to impacts on climate change (CC), acidification potential (AP), eutrophication potential (EP), cumulative energy demand (CED), terrestrial ecotoxicity (TE), and land occupation (LO) in Brazilian (BR) and French (FR) scenarios of pig production. Mean results for soybean meal from South Brazil.

Interactions between effects of the feeding program, the use of AA, and the soybean origin on the environmental impact of climate change (A), acidification potential (B), and eutrophication potential (C) for the Brazilian (BR) and French (FR) contexts of pig production. 2P, 2-phase; 4P, 4-phase; DMP, multiphase; IDF, individual daily feeding; noAA, no AA; withAA, with AA; lowCP, without constraints in the CP content; SO, soybean from South region; CW, soybean from Center West Brazil; SOY, soybean meal as sole protein source; MIX, diversified protein sources.
