Muscle Tearing

(276) This is a common condition in sows and first litter gilts whereby the muscle fibres are torn away from their attachment to the bone and periosteum. This occurs where muscles are attached to the inner surfaces of the elbow and knee joints, and the points of attachment to the pelvis. Affected sows show considerable pain and often adopt a dog sitting position. Inflammation of bone and periosteum result (periostitis). Torn muscles arise as a sequel to OCD, trauma and fighting, slippery surfaces and weak bones. Affected sows as soon as they are identified should be moved to a solid floor area that is deep bedded where the grip for the foot is firm. Soiled or grass areas are ideal. If this is done most will recover.
