Ovivac P For Lambs

All MSD Animal Health’s sheep pasteurella vaccines are produced using bacteria which express a high number of iron regulated proteins (IRPs), thus mimicking the situation that occurs when the bacteria infect an animal naturally. As part of the immune response to vaccination, antibodies against these IRPs are produced which then attach to any invading bacteria, causing them to be starved of iron and die. This occurs at an early stage before the bacteria are able to produce large amounts of damaging toxins. Since all strains of Mannheimia haemolytica and Bibersteinia trehalosi express similar IRPs, the vaccines also provide good cross protection against other strains of these bacteria.

Ovivac P Plus is an inactivated vaccine for immunisation against four key clostridial bacteria and Mannheimia haemolytica. 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 lambs. 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 2ml 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. 

Description

Combined 4 in 1 Clostridial plus Pasteurella vaccine.For the active immunisation of lambs as an aid in the control of pulpy kidney, tetanus, braxy and blackleg caused by the above listed organisms. The vaccine may be used as an aid in the control of pneumonic pasteurellosis in sheep of all ages from a minimum age of 3 weeks and in the control of systemic pasteurellosis in weaned fattening and breeding sheep. All lambs not previously vaccinated with Ovivac P Plus must receive two injections, each of 2.0 ml, separated by an interval of 4-6 weeks. Thereafter they must receive booster injections at intervals of not more than 12 months.
Ovivac P Plus should not be used in lambs less than 3 weeks of age.

Indications for use

For the active immunisation of lambs as an aid in the control of pulpy kidney, tetanus, braxy and blackleg caused by Cl.perfringens type D, Cl.septicum, Cl.tetani and Cl.chauvoei. The vaccine may be used as an aid in the control of pneumonic pasteurellosis in sheep of all ages from a minimum age of 3 weeks and in the control of systemic pasteurellosis in weaned fattening and breeding sheep.

Dosage & Administration

The vaccine should be administered by subcutaneous injection in the lateral side of the upper neck observing aseptic precautions.

All lambs not previously vaccinated with Ovivac P Plus must receive two injections, each of 2.0 ml, separated by an interval of 4-6 weeks. Thereafter they must receive booster injections at intervals of not more than 12 months. On farms where the incidence of pasteurellosis is high, a supplementary booster vaccination with Ovipast Plus (Pasteurella vaccine) may be required 2-3 weeks prior to expected seasonal outbreaks.

Ovivac P Plus should not be used in lambs less than 3 weeks of age due to the possible immunological incompetence of the very young lamb and competition from any maternally derived colostral antibodies.
