Space requirements of finishing pigs fed to a heavier weight (removed individually)

Fitzner, G.E.; Nichols, David A.; Hancock, Joe D.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2010-04-02)

Space allowances of 6, 8, 10, and 12 ft2 were evaluated for pigs fed from 120 to 250 lb. The management system used was to remove pigs individually as they reached 250 lb, which provided increasing space per pig. Using ...
