Method of administration:
• Vaccination dose - 2 ml
• Immunity inducing: The pregnant heifers (or still unvaccinated cows) are vaccinated twice at the interval of 21 days, namely, 7 - 5 weeks and 4 - 2 weeks before the first expected calving.
• The next vaccinations are performed once, namely, before each next calving.
• The vaccine is administered intramuscularly - preferably at gluteal region.
In order to ensure the effective prevention of calves against infection, the gastrointestinal tract of calves shall be saturated with colostrum obtained from the vaccinated cows for the first 2 - 3 weeks of their life. A calf shall drink the adequate colostrum volume obtained from the vaccinated cows within 6 hours after its birth.
Taking into account that a calf is not fed with its mother, colostrum (and later milk) should be collected from the vaccinated cows during the first 6 - 8 milking; the colostrum and milk obtained as above should be stored either frozen or (for not later than 14 days) chilled to the temperature between 2 °C and 8 °C. The daily dose of colostrum (and, later, milk) for a calf is 2.5 - 3.5 l daily for at least the first two weeks of life. The optimum protection of calves against the infection can be reached using the method as mentioned above if all cows in the herd are vaccinated.
Advice on correct administration:
- The vaccine is administered intramuscularly - preferably at gluteal region.
All breeding animals in the stock should be vaccinated, and the adequate colostrum volume shall be administered to calves not later than 6 hours after their calving.
Warm the vaccine to the temperature between 15 °C - 25 °C and shake the content of the vial before use.
