One less vaccination next spring
Wouldn’t it be great to have one less vaccination to carry out during the spring?
There is more than enough work on farms around Ireland at the moment and there is barely enough help to get all the jobs done.
Disease prevention is therefore more important than ever, as the system is at break point even when everything is working, so a few sick animals is more than many can cope with. Dropping a vaccine for the sake of it would be fool hardy, but planning ahead and moving elective work to a quieter time of year might be a smart move.
Traditionally, heifers are vaccinated against Lepto in mid-February and they receive their second vaccination in mid-March when all the cows receive their annual booster; a lot of work and handling at a busy time of year.
It is now possible to booster cows against Leptospirosis at any time of year; it doesn’t have to be done in the spring.
Spirovac can be used to protect cows and heifers against Lepto infections and this vaccine provides 12 months duration of protection.
But, most important, the vaccine can be given ANY TIME OF YEAR thus at a more convenient time than spring, perhaps at drying off.
If cows were vaccinated last March, they will need a booster this March and then next spring’s vaccine could be brought forward to drying off this autumn; and simply repeated every November/December thereafter.
Traditionally heifers receive their first course of Lepto vaccinations as yearlings, just before they go to the bull.
