Busting BVDV Myths

The effects of bovine viral diarrhea virus (BVDV) are wide-ranging in terms of reproductive issues, adult and calf health, and production. Much as been written about BVDV over the years and much has been and is still being discovered, but in spite of that misinformation “myths” about BVDV still remain. Dan Givens, DVM, PhD, Auburn University, discusses the plausibility of the most persistent myths about BVDV. FULL STORY »

How bad could it be?

An outbreak of foot and mouth disease in the United States could shut down beef and pork exports and profoundly disrupt our markets for years. Fortunately, we have not had FMD in this country since 1929, and experts around the country are working to keep it that way. But today, with more international movement of people and animals and greater dependence on export markets, the risk and consequence of an outbreak are far greater. FULL STORY »

Is Schmallenberg virus a U.S. concern?

Even firemen are not crypto-proof

Last week’s CDC Morbidity and Mortality Weekly Report detailed a case of firefighters in Indiana and Michigan contracting cryptosporidiosis after saving baby calves from a barn fire. Out of the 34 responding firefighters, 20 reported gastrointestinal illness about a couple of weeks after responding to the fire. Cryptosporidium parvum was identified in human stool specimens, calf fecal samples, and a swimming pond from which water was used to help extinguish the fire. FULL STORY »

The many faces of E. coli

Humans have a love-hate relationship with the species of bacteria known as Escherichia coli. We hear about outbreaks of food-borne illness associated with E. coli, (and those are becoming less frequent) but many are unaware of the other roles E. coli plays. Those roles are outlined in a new report titled "E. coli: Good, Bad & Deadly,” produced by the American Academy of Microbiology. FULL STORY »

FMD outbreak simulation study

In a worst-case scenario simulation of a foot-and-mouth disease (FMD) outbreak in Mexico, researchers found that establishing a good surveillance system and raising a more resilient breed of cattle could lessen the blow to the Mexican cattle industry should an outbreak of FMD or other infectious disease occur.

Economics of trich

Beside being a herd health and biosecurity nightmare, trichomoniasis is costing producers missed dollars across the country. In states like Arkansas, emergency bull testing requirements were passed this summer due to outbreaks. In Colorado, the Board of Animal Health is reminding producers of the importance of testing because of seven trich-positive areas in that state. The list of affected states could go on. FULL STORY »

Preventing BRDC

Decreasing bovine respiratory disease complex (BRDC) in feedlot cattle can decrease mortality and morbidity as well as reduce treatment and subclinical costs of the disease. Cattle free from respiratory disease have improved performance including better average daily and gain and feed conversion. Chris Chase, DVM, PhD, South Dakota State University, says management factors that go along with preventing BRDC include eliminating stress factors where possible. Recognize the “critical period” for disease detection – the three weeks that follow weaning, placing on feed and shipping of cattle. FULL STORY »
