Best Vaccination Schedule
The Guardian® vaccination protocol is simple and convenient.
| Dosage & Route | 2 mL SQ |
| Primary Dose | 12 weeks precalving |
| Booster Dose (Beef) Booster Dose (Dairy) | 3-6 weeks after primary dose* 3-6 weeks after primary dose* |
| Annual Revaccination | 5-7 weeks precalving |
| Bottle Sizes | 20 mL (10 doses) & 100 mL (50 doses) |
| Preslaughter Withdrawal | 60 days |
*Needed only for first-time vaccination with Guardian.
Finishing the vaccination protocol before the beginning of colostrum formation ensures high levels of antibody are available to concentrate in colostrum. Vaccinating cows less than 5 weeks before calving may be too late to allow for optimal antibody levels in colostrum.
