BVD

CSI-Dairy: Nabbing the culprits behind calfhood pneumonia

Numerous ‘culprits’ exist on dairy farms, robbing herd performance and injuring the dairy’s bottom line. Identifying and arresting the offender isn’t always easy, and often requires a full investigation, gathering and analyzing evidence on the farm and in the lab. Uncovering the source of pneumonia in calves can be a difficult challenge.

Don’t forget about BVD

Scours, pneumonia, then a bout of coccidiosis at weaning; she is just a “poor doer” is often what I hear. Even the best calf-management programs have some challenging disease cases. Often, individual calves that are unthrifty and have multiple diseases are a result of colostrum feeding issues (passive transfer) or a difficult birth. But let’s not forget the calf persistently infected with bovine viral diarrhea (BVD).

BOVINE VIRAL DIARRHEA (BVD)

What is Bovine Viral Diarrhea?


Bovine Viral Diarrhea (BVD) is a disease of cattle caused by the Bovine Viral Diarrhea Virus (BVDV). The virus is widespread and most herds are at risk for infection. In the susceptible herd, BVD can be a serious, costly disease.

Respiratory Disease of the Bovine Neonate

Respiratory disease is a constant challenge for dairy replacement heifer rearing systems, and is responsible for 21.3% of mortality in preweaned calves and 50.4% of deaths in weaned heifers.1 There are many negative long-term consequences for survivors of subclinical, clinical, and chronic calf pneumonia including poor growth, reproductive performance, milk production, and longevity.2–4 These calves also become sources of infection for other calves, and can cause outbreaks after weaning in group pens.5 Contamination of the environment with bacterial and viral pathogens is the obvio

The Association Between Serological Titers in Infectious Bovine Rhinotracheitis Virus, Bovine Virus Diarrhea Virus, Parainfluenza-3 Virus, Respiratory Syncytial Virus and Treatment for Respiratory Disease in Ontario Feedlot Calves

A seroepidemiological study of the association between antibody titers to infectious bovine rhinotracheitis, parainfluenza-3, bovine virus diarrhea and bovine respiratory syncytial viruses, and treatment for bovine respiratory disease was conducted. A total of 322 calves from five different groups were bled on arrival, then one month later all cases (cattle treated for bovine respiratory disease) were rebled together with an equal number of controls (cattle not treated for any disease).

Herd Health Programs For A Beef Cattle Enterprise

Often, we tend to think of a health program as simply a vaccination schedule. The reality is that vaccinations are important but other management factors will play a larger role in the health status of our herd and the financial success of your beef cattle enterprise. Reproductive management, nutrition, parasite control, and implant protocols are an integral part of our success and have a large impact on the health status of the herd. If we look at total production, we see that integrating management and health increase our financial success.
