Shoulder lesions (SL) were on average found in about 1/3 of loose-housed lactating sows in 78 Swedish herds (3). Main risk factors are poor body condition, parity number, lameness and MMA (1,2).
In addition, environmental factors such as floor type may contribute to the development of SL during lactation (1,2).
