"Establishing A Cow/Calf Herd
Health and Preconditioning Program"
------------------------- Dan Bergerud DVM Cass Veterinary Services Virginia, Illinois -------------------------
Reasons for having a herd
health program:
Control health problems and improve
production on your farm.
Insurance policies against diseases
establishing themselves on your farm
Control health problems after the
calves leave your farm.
To have your calves ready to gain
weight when they enter the feedlot.
Required as part of participation
in alliances. (Green Tag Program, Pfizer Weanvac Program, retained ownership
programs, etc.)
Improve communication with the buyer
about the health status and production potential for your calves.
Points to Ponder:
Nutrition: Keep in mind the role
nutrition has on the animals' ability to fight off disease and respond
properly to vaccines.
Communication with feedlot operator:
If a health problem, nutritional deficiency or production problem occurs
after your calves leave the farm you need to know if there was something
you could have done to prevent it. Seek out advice as to how to solve the
problem. Alliances will help improve this communication barrier.
Beef Quality Assurance: Give all
injections SQ in the neck region. Injection lesions contributed $7.05 of
the loss per fed steer/heifer.
Compared to nonvaccinated calves,
calves vaccinated at the farm for the bovine respiratory disease complex
had 20 percent to 30 percent less sickness, 40 percent less death loss
and similar or improved feedyard performance.
