Extremities of pigs often show swelling of various size and consistency. The aim of the present investigation was to determine the cause of the swelling with special emphasis on housing conditions. A total of 168 animals kept on slatted and/or partly slatted floors and 55 pigs kept on straw were examined. The swelling was partially caused by connective tissue proliferation only, but more often consisted of non inflamed subcutaneous bursae. Skeletal changes near the periost could never be seen. In pigs kept on straw weals and subcutaneous bursae practically never developed, whereas in animals kept on concrete, these changes did occur more frequently and were more pronounced with time.
猪的四肢常常出现大小和质地各异的肿胀。本研究的目的是确定肿胀的原因，特别关注饲养条件。总共检查了168头饲养在板条地板和/或部分板条地板上的猪以及55头饲养在稻草上的猪。肿胀部分仅由结缔组织增生引起，但更常见的是由非炎症性皮下黏液囊组成。从未见过骨膜附近的骨骼变化。饲养在稻草上的猪几乎不会出现风疹块和皮下黏液囊，而饲养在水泥地上的猪，这些变化更频繁地出现，并且随着时间的推移更为明显。
