Black Quarter (BQ) in Cattle: Real Field Clinical Case Study Young cattle appear to be at greatest risk for C. chauvoei muscular infections, and most cases occur in well cared for animals 6 to 24 months of age. It may occur between 2 and 3 years of age. C. sordelli may have a similar pathogenesis because it has been associated with muscle bruising in rapidly growing beef cattle.

Lumpy Skin Disease LSD a Field Clinical Case Study Circumscribed, firm, round and raised cutaneous nodules on the head, neck, limbs, udder, genitalia and perineum Nodules may become necrotic and eventually fibrotic and persist for several months Vesicles, erosions and ulcers in the mucous membranes of the mouth and alimentary tract and in the trachea and lungs may be found Limbs and ventral parts of the body, such as the dewlap, brisket, scrotum and vulva, may be oedematous

Bovine Ephemeral Fever in Cattle | BEF | a Field Case Study A common disease of cattle in Bangladesh. Usually occurs at march to may in Bangladesh.

BEF

In dairy cattle, the condition is not thought to be inherited and seldom recurs in subsequent parturitions. Although the exact cause for an individual patient may be difficult to determine, predisposing causes include dystocia, tenesmus, and hypocalcemia. Primiparous cows can be affected, but pluriparous ones are probably at greater risk. Prolapse of the uterus also is fostered by confinement, lack of exercise, and gravitational effects when cattle are allowed to calve with their hindquarters lower than their forequarters, as happens when confined cows calve into the drop of conventional barns. Uterine atony is the common inciting cause and is frequently associated with hypocalcemia in multiparous dairy cattle. Prolapse usually occurs within hours of calving and almost always within 24 hours of calving. Instances of uterine prolapse occurring several days following calving are cited by many practitioners but are extremely rare.

There are other factors that contribute to the development of hypocalcemia in dairy cattle, specifically age, breed, and endocrinologic factors such estrogen levels. With increasing age there is a reduced pool of calcium available for absorption from bone as a result of diminishing numbers of bone cells, and this is a reason why heifers, in whom osteoblastic activity is high, do not suffer from clinical milk fever.
