Imported defatted soybean meal is the most common supplemental protein source used for feeding pigs. It is available as a commodity world-wide. Most soybean meal used in Europe is imported from South America. Partially replacing imported soybean meal with extruded full-fat soybeans in pigs’ diet could be an attractive and financially beneficial alternative in a country like Bulgaria where the facilities for production of soybean meal is not widely available. It is especially attractive in mixed-farming systems where soybean production and use (in feed) are closely connected.
