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.
Dairy Vietnam -There was an increase in the number of reports of bloat from NADIS vets this spring. Bloat is most commonly seen in spring and autumn, when grass growth is at its peak. It is one of the most common causes of death in adult cattle at grassp

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).
INDIA - The government today said the foot and mouth disease in livestock sector is resulting into direct economic loss to the tune of Rs 20,000 crore per annum.
US - Scientists at the ARS Center for Grain and Animal Health Research (CGAHR) in Manhattan, Kansas, and in Kenya are developing and evaluating control strategies for viruses like Rift Valley fever, which is transmitted by mosquitoes.
AFRICA - Cattle are extremely vulnerable to ticks, mites and flies which can transmit blood parasites, cause irritating wounds and then infections. In order to control them farmers must dip their cattle in a pesticide. This is impractical and expensive for poor farmers with just a small number of livestock.
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.
