Ovivac® P Plus
The economic impact of losses due to pasteurellosis and clostridial diseases can be devastating. Lamb deaths are only part of the loss. Even surviving lambs are liable to suffer long term losses in condition and weight. While they may look perfectly well, unseen damage to the lungs is common after pneumonia strikes and only becomes apparent when reduced performance leads to later or fewer finished lambs1.
Vaccinating ewes with Heptavac P Plus initially helps protect their lambs via the colostrum. However, this passive immunity wanes, leaving lambs unprotected. To immunise growing and store lambs after this period, two 2 ml doses of Ovivac P Plus, 4 to 6 weeks apart, are required. The course can be started from as early as three weeks of age.
Ovivac P Plus contains antigens from four clostridial species and antigens from the most important serotypes of Mannheimia haemolytica and Pasteurella trehalosi.
