Why a Vaccination Schedule Matters
A consistent vaccination program is one of the cheapest forms of insurance you can buy for your cattle herd, protecting against diseases that can cause abortion, death, or long-term production losses. Working with a veterinarian to build a schedule tailored to your region and herd type ensures you’re covering the risks that actually matter locally.
Calfhood Vaccinations
Calves typically receive their first round of vaccinations at branding or turnout, covering clostridial diseases like blackleg along with respiratory viruses such as IBR and BVD. A booster is usually given three to four weeks later to build full immunity before the stress of weaning.
Pre-Weaning Boosters
Giving respiratory and clostridial boosters two to three weeks before weaning, rather than on weaning day itself, allows calves to build immunity before facing the stress of separation. This timing has been shown to significantly reduce sickness rates during the weaning period.
Breeding Herd Vaccinations
Cows and heifers typically need annual boosters for reproductive diseases including BVD, IBR, leptospirosis, and vibriosis, ideally given several weeks before the start of the breeding season. Reproductive vaccines are especially important since diseases like BVD can cause abortion and persistently infected calves.
Bull Vaccinations
Herd bulls should follow a similar annual vaccination schedule as cows, with particular attention to vibriosis and trichomoniasis protection since bulls can transmit reproductive diseases throughout the herd during breeding season.
Building Your Herd Calendar
Mark key dates for calving, weaning, and breeding on a calendar, then work backward to schedule vaccines at the appropriate intervals before each event. Keeping simple records of what was given and when helps you stay consistent year after year and gives buyers confidence when you sell cattle.
