Parvovirus Vaccine For Pigs

Porcine parvovirus infection (PPV) is a common and important cause of infectious infertility. PPV is a robust virus that multiplies normally in the intestine of the pig without causing clinical signs and is ubiquitous in pig populations world-wide. PPV is one of the organisms listed as responsible within the Stillbirths Mummification Embryonic Death and Infertility (SMEDI) syndrome. In larger herds it is almost certain to be present and is an infection you have to live with and manage, rather than try to eliminate. In smaller herds with a previously PPV positive pig, it may or may not have died out.

Most viruses do not survive outside the host for any great length of time, PPV is unusual in that it can persist in the environment for many months and it is resistant to most disinfectants, and the most likely reason as to why is widespread and difficult to eliminate. PPV is harmless to humans and other farm animals and is not a food safety risk.

Features of Parvovirus Vaccine For Pigs

In acute outbreaks of the disease the infection itself causes no clinical signs other than the presence of mummified piglets, 3 to 16cm in length, at farrowing. Once inside the womb PPV spreads slowly from one foetus to another and as a result the sizes of mummified pigs will vary within the litter, and depending upon the gestation age when the sow became infected, some may live.

Other indicative observations are:

  1. An increased numbers of stillbirths. These are associated with the delay in the farrowing mechanism which occurs because of the presence of mummified piglets.
  2. Small litters associated with embryo loss before 35 days gestation.
  3. An increase in low birth weight piglets but neonatal deaths are not affected.
  4. Small mummified piglets in the afterbirth present.
  5. Abortions associated with PPV are uncommon.
  6. Increased returns to oestrus increase due to total embryo absorption before 35 days.
  7. Sporadic cases of individuals within a herd are usually confined to newly purchased naïve gilts or sows.
  8. Reduced efficacy of the vaccine in gilts as the maternal immunity may persist up to 7 months of age in the live piglets but only in a few gilts – which can interfere with the vaccine response.
  9. In larger sero-positive (antibodies present to PPV) herds up to 50% of gilts may be sero-negative at the point of mating.
  10. No other signs of ill health in the breeding females.
  11. No vaccination programme in place.

Benefits of Parvovirus Vaccine For Pigs

Approved for use in healthy breeding swine as an aid in preventing reproductive failure caused by porcine parvovirus.

Help protect against some of the leading causes of reproductive failure in swine.

Safely administered to pre-breeding gilts and that a dose can be safely given to pregnant sows as late as two to four weeks prior to farrowing.

It’s important to contact your veterinarian to determine the best vaccination program for your site.

Indication: 

Vaccination of sows and gilts in order to protect their embryos and fetuses against porcine parvovirus infection.

Dosage: 

2 mL/pig by deep intramuscular injections behind the ear.

  • –Initial vaccination:
    • Gilts: 1 vaccination, preferably at 6-7 mos of age but at least 2 wks before first mating.
    • Sows: 1 vaccination, at least 2 wks before mating. Revaccination: 1 vaccination per year at least 2 wks before mating.

Precaution: 

Vaccinate healthy animals only.

Packaging:

 Vial 20 (10 doses), 50 mL (25 doses).
