Startvac (1Dose) 2Ml X 20 Vials

Startvac is used to strengthen the immunity of whole herds of otherwise healthy dairy cows in herds that are known to have problems due to mastitis (inflammation of the udder due to infection). The strengthened immunity reduces the number of cows affected and the severity of clinical signs. Startvac is given to all healthy cows in a herd, during and after pregnancy. It is given as three injections into the neck muscle: the first is given 45 days before the cow is expected to give birth, the second 35 days later, and the third after another 62 days. The full course of injections should be repeated for every pregnancy.
