Great Ideas on Pneumonia

In a brief article published in the August 7 issue of Progressive Dairyman, " Defend dairy cows from respiratory disease" (pp 55-56) Dr. Amelia Woolums from the Department of Large Animal Medicaine, University of Georgia, captures the essentials about:
  • Pneumonia in adult cows: How often does it occur and what are the signs?
  • What is pneumonia, and why does it matter?
  • How can pneumonia  be treated or prevented?
She prepared a great summary on vaccinating for pneumonia that was published as a sidebar. 

She says:
"The common respiratory viruses for which vaccine exist in the U.S. include:
1. infectious bovine rhinotracheitis virus (IBR), also known as bovine herpesvirus-1 (BHV-1)
2. bovine respiratory syncytial virus (BRSV)
3. bovine viral diarrhea virus (BVDV)
4. parainfluenza type 3 virus (PI-3V)"

Of special interest to those of us working with calves she notes:
1. Evaluate the proven efficacy of a vaccination.
2. Give vaccines time to protect the animal. The strongest response occurs at least two weeks after the vaccination is given. 
3. For the most reliable protection the calf should receive two doses of the vaccine, separated by approximately four weeks, before they are exposed to infection.

If you missed this article see if you can find the August 7 issue - it's the one showing field work chopping corn on the cover.
