Startvac Vaccine – 5 Dose or 25 Dose
What is Startvac?
Startvac is a polyvalent inactivated vaccine for cattle (cows and heifers) used as part of a herd plan to reduce the incidence of subclinical mastitis and the incidence and severity of clinical mastitis caused by Staphylococcus aureus, coliforms and coagulase-negative staphylococci. Immunity develops across the programme from around day 13 after the first injection until roughly day 78 after the third injection.
When and how to vaccinate
Route & dose: 2 mL by deep intramuscular injection in the neck; alternate sides between doses.
Primary course per lactation:
45 days before the expected calving date
35 days later (≈10 days before calving)
62 days after the second dose (≈52 days post-calving)
Repeat the full programme for each gestation.
Allow the vial to warm to +15 to +25 °C and shake before use. Use aseptic technique.
Where Startvac fits in a mastitis plan
Vaccination should sit alongside milking routine discipline, dry-off management, housing & bedding hygiene, nutrition, cow comfort and monitoring. Whole-herd immunisation is recommended in herds with recurring mastitis pressure to improve udder-health outcomes and milk quality.
Safety, use in breeding animals & expected reactions
Can be used during pregnancy and lactation.
Transient injection-site swelling or a short-lived temperature rise may occur.
Contains mineral oil adjuvant; accidental self-injection requires urgent medical attention. Keep out of reach of children and follow safe handling protocols.
Storage, broach life & withdrawal
Refrigerate 2–8 °C, protect from light, do not freeze.
After first opening, use within 10 hours (store during use at 15–25 °C).
Meat/milk withdrawal: Zero days.
Pack sizes offered
5 Dose (10 mL) and 25 Dose (50 mL) multi-dose vials.
Good practice tips
Use clean automatic vaccinators with a vented draw-off spike for accurate 2 mL dosing. Keep a cold-chain to farm and during sessions. Record batch/expiry against animal groups to support pharmacovigilance.
