For BRSV, and a host of other cattle diseases, plan on the
Proper Vaccine at the Proper Time
And don’t forget the booster shots By Gary DiGiuseppe N
OT ALL ANTIBODIES ARE CREATED EQUAL. THAT MEANS when it comes to supplementing the protection calves receive from their mothers’ fi rst milk
with vaccines and boosters, timing is critical. Dr. Mark Spire, DVM, technical services manager
for Merck Animal Health, says a set of calves needs to be treated as a population and not individuals. “You don’t think about how you’re going to vac-
cinate a calf, but how you’re going to vaccinate the entire group,” he says, and it all starts with the fi rst milk — the colostrum — that sets the stage for further protections the calf will receive from disease through- out its lifetime. The colostrum contains the antibodies developed
by the cow from the vaccines or disease agents she’s already received or been exposed to during her lifetime. These maternal antibodies will protect the calf for the fi rst several weeks of life, but the antibody protection eventually wears off, though not all at once. “We’ve found that certain organisms that made
antibodies in the mother will disappear at different times from the calf’s protection umbrella,” says Spire. “For example, both blackleg and lepto species tend to be gone pretty much by 8 weeks of age. When we get to things like PI3, BRSV and Histophilus, those will last about 10 to 12 weeks before we see them gone out of the vast majority of the population. Then we see the IBR or ‘red-nose’ antibodies disappear at about 4 months of age, and then we’ll see BVD typically disappear at about 5 to 7 months of age.” The importance of the colostrum in setting the stage for the calf’s future disease protection regimen
How long could you expect a vaccine to provide excellent protection?
