Disorders of the Claw Capsule in Cattle

Sole Ulcer

(Pododermatitis circumscripta)

Sole ulcers commonly affect one or both lateral hind claws, predominantly in heavy, high-yielding dairy cattle kept under confined conditions. A sole ulcer is a circumscribed lesion located in the region of the sole/bulb junction, usually nearer the axial than abaxial margin. Damage to the dermis is associated with a circumscribed zone of localized hemorrhage and necrosis. The incidence is variable, but in some herds up to 50% of mature cows can be affected.

In all cows the uterus is contaminated with bacteria after giving birth, but this does not necessarily indicate an infection, or the development of a uterine disease (Azawi, 2008). Normally, cows manage to control this contamination and even the most severe infections during the involution of the uterus, but if the contamination results in an infection and is persistent, a uterine disease will develop (Lewis, 1997).

Milking Machine and Mastitis Control Handbook

Mastitis is the most costly disease in the dairy industry, with the biggest loss from subclinical mastitis, when bacteria are already in the udder. These organisms destroy milk-secreting tissue and thus lower milk production.

Subclinical mastitis cannot be detected on a strip plate, but it is found through a high somatic cell count. A count of 1 million cells/ml indicates that over 30% of a herd's quarters are infected with mastitis.
