Environmental role in the epidemiology, transmission and diagnosis of Johne's disease (Proceedings)

November 1, 2010

Mycobacterium avium subspecies paratuberculosis (MAP), the causative agent of Johne's Disease (JD), is prevalent worldwide. The NAHMS Dairy 1996 study, estimated 21.6% of the dairy herds in the US were infected with MAP, resulting in annual economic losses for the dairy industry of $200-250 million.

Common neurological diseases in food animal (Proceedings)

November 1, 2010

Maybe this doesn't really fit "common" but it is always interesting to hear about cases. The main thing about rabies in cattle (and other species) is that signs are quite variable and inconsistent. Certain signs should be "red flags" for bovine rabies. Oftentimes cattle with rabies will have some history of hindlimb ataxia, weakness, or paralysis (this in itself is typical of many bovine diseases but for cattle exhibiting these signs, rabies should be considered).

Dealing with a sick cria and an anxious client can be quite daunting at times. This task becomes less daunting when one understands the main problems and how to manage them. Neonatal crias are typically admitted to the UT College of veterinary medicine due to prematurity/weakness/inability to stand, suspected or real failure of passive transfer (FPT), and septicemia.

Role of bovine viral diarrhea virus in feedlots (Proceedings)

November 1, 2010

Bovine viral diarrhea virus (BVDV) is one of the most important infectious agents of cattle. The annual economic loss caused by BVDV is difficult to quantify but certainly is significant. The insidious nature of BVDV combined with the biology of the virus and complex disease pathogenesis has made control and prevention of this virus challenging.

Case study: monensin (Rumensin) toxicity in dairy replacement heifers (Proceedings)

November 1, 2010

Many dairy producers use Rumensin? (Elanco Animal Health) in dairy heifers as an aid to controlling coccidiosis and for improved feed efficiency. Rumensin? also is approved for use in lactating cows as a tool for improving milk production efficiency. Monensin, the active compound in Rumensin?, has a very wide safety margin for humans and cattle. But, it can be toxic if not fed according to the FDA-approved label. In other species, such as horses, monensin can be extremely toxic.
