Vaccinating cows and heifers prior to spring breeding has proven
to be a sound management practice that provides several benefits
for cows, calves and producers. Cows have better pregnancy and
conception rates. Calves are heavier, healthier and more
uniform. And producers end up with better weaning percentages, a
higher-value calf crop, less sickness and low medicine costs.
According to Dr. H. Nielsen, professional services veterinarian,
Novartis Animal Health, ensuring breeding females have
protection from respiratory, reproductive and clostridial
diseases at this critical juncture sets the stage for a
successful and efficient reproduction program. “Ultimately, the
goal is to ensure a healthy calf from every cow,” said Dr.
Nielsen. “Vaccinating cows before breeding elevates their
immunity levels, which protects them from diseases that
undermine reproduction. And increasing immunity levels in cows
right before breeding season can also help to achieve a shorter
breeding cycle and more uniform calf crop.” Niels
