Best Vaccines For Pigs To Ensure Healthy Growth

Raising healthy pigs is crucial for both small-scale farmers and large commercial operations. Disease outbreaks can lead to significant economic losses due to mortality, reduced growth rates, and increased veterinary costs. Vaccination plays a vital role in preventing infectious diseases, ensuring optimal growth, and improving overall herd productivity.

The best vaccines for pigs, focusing on their importance, recommended vaccination schedules, and best practices for administration. By implementing a proper vaccination program, pig farmers can safeguard their herds against common pathogens and promote healthy growth.


Why Vaccinate Pigs?

Vaccination is a cost-effective method to:

  • Prevent deadly diseases (e.g., swine fever, PRRS)
  • Reduce antibiotic use by preventing infections
  • Improve feed conversion efficiency (healthy pigs grow faster)
  • Enhance immunity in piglets (via maternal antibodies)
  • Minimize economic losses from disease outbreaks

Without vaccination, pigs are vulnerable to viral, bacterial, and parasitic infections that stunt growth and increase mortality rates.


Core Vaccines for Pigs

1. Porcine Circovirus Type 2 (PCV2) Vaccine

Disease: PCV2 causes Porcine Circovirus Associated Disease (PCVAD), leading to:

  • Post-weaning multisystemic wasting syndrome (PMWS)
  • Respiratory and reproductive issues
  • Poor growth rates

Vaccine Type: Inactivated or subunit vaccines.
Recommended Schedule:

  • Piglets: Single dose at 3-4 weeks of age
  • Sows: Pre-farrowing vaccination to boost maternal immunity

Benefits:

  • Reduces mortality and improves weight gain
  • Prevents secondary infections

2. Porcine Reproductive and Respiratory Syndrome (PRRS) Vaccine

Disease: PRRS virus causes:

  • Reproductive failure in sows (abortions, stillbirths)
  • Respiratory disease in piglets and growing pigs

Vaccine Type: Modified live virus (MLV) or killed virus.
Recommended Schedule:

  • Piglets: Vaccinate at 2-3 weeks (MLV) or as recommended
  • Gilts/Sows: Pre-breeding and pre-farrowing boosters

Benefits:

  • Reduces viral shedding
  • Improves reproductive performance

3. Mycoplasma hyopneumoniae Vaccine (Swine Pneumonia Vaccine)

Disease: Causes enzootic pneumonia, leading to:

  • Chronic coughing
  • Reduced growth rates
  • Secondary bacterial infections (e.g., Pasteurella)

Vaccine Type: Bacterin (killed bacteria).
Recommended Schedule:

  • Piglets: Single dose at 1-3 weeks, booster at 3-4 weeks
  • Sows: Pre-farrowing vaccination

Benefits:

  • Reduces lung lesions
  • Improves feed efficiency

4. E. coli Vaccine (Neonatal Diarrhea Prevention)

Disease: Enterotoxigenic E. coli (ETEC) causes severe diarrhea in piglets.
Vaccine Type: Bacterin or subunit vaccine.
Recommended Schedule:

  • Sows/Gilts: Vaccinate 2-3 weeks before farrowing
  • Piglets: May receive oral antibodies via colostrum

Benefits:

  • Prevents fatal scours in newborn piglets
  • Reduces pre-weaning mortality

5. Swine Erysipelas Vaccine

Disease: Caused by Erysipelothrix rhusiopathiae, leading to:

  • Diamond-shaped skin lesions
  • Arthritis, fever, and sudden death

Vaccine Type: Killed or live attenuated.
Recommended Schedule:

  • Piglets: First dose at 8 weeks, booster at 12 weeks
  • Breeding stock: Every 6 months

Benefits:

  • Prevents acute and chronic infections
  • Reduces joint damage

6. Parvovirus Vaccine (Reproductive Protection)

Disease: Porcine parvovirus (PPV) causes:

  • Stillbirths, mummified fetuses
  • Infertility in sows

Vaccine Type: Inactivated virus.
Recommended Schedule:

  • Gilts/Sows: Vaccinate before first breeding and boost before farrowing

Benefits:

  • Protects against reproductive losses
  • Essential for breeding herds

7. Foot-and-Mouth Disease (FMD) Vaccine (Where Endemic)

Disease: Highly contagious viral disease causing:

  • Blisters on feet and mouth
  • Lameness, fever, death in piglets

Vaccine Type: Inactivated virus.
Recommended Schedule:

  • Piglets: First dose at 8-12 weeks, boost every 6 months

Benefits:

  • Mandatory in FMD-prone regions
  • Prevents trade restrictions

8. Actinobacillus pleuropneumoniae (APP) Vaccine

Disease: Causes severe pleuropneumonia, leading to:

  • Sudden death
  • Bloody nasal discharge

Vaccine Type: Bacterin.
Recommended Schedule:

  • Piglets: Vaccinate at 6-8 weeks, booster at 10-12 weeks

Benefits:

  • Reduces mortality in growing pigs
  • Improves respiratory health

Optional Vaccines (Based on Farm Risk Assessment)

  • Rotavirus (for neonatal diarrhea)
  • Salmonella (for food safety in pork production)
  • Atrophic Rhinitis (caused by Bordetella bronchiseptica & Pasteurella multocida)
  • Swine Influenza (SIV) (for herds with respiratory challenges)

Best Practices for Pig Vaccination

  1. Follow Manufacturer Guidelines – Each vaccine has specific storage, dosage, and timing requirements.
  2. Proper Needle Size – Use 16-18 gauge needles (½ to ¾ inch for piglets, 1 inch for adults).
  3. Correct Injection Site – Intramuscular (neck) or subcutaneous (behind the ear).
  4. Avoid Stress During Vaccination – Handle pigs gently to prevent immune suppression.
  5. Keep Records – Track vaccine batches, dates, and pig responses.
  6. Combine with Good Management – Vaccines work best with proper nutrition, biosecurity, and hygiene.

Here are ten frequently asked questions (FAQs) about pigs:

1. Are pigs intelligent?

Yes! Pigs are among the most intelligent animals, often compared to dogs and even primates. They can solve puzzles, learn tricks, and have excellent long-term memory.

2. Do pigs sweat?

No, pigs have very few sweat glands, which is why they roll in mud to cool down. The mud also protects their skin from sunburn and insects.

3. How long do pigs live?

Domestic pigs typically live 12–15 years, but some can reach 20 years with proper care. Wild boars usually live shorter lives due to predators and environmental factors.

4. Are pigs clean animals?

Despite their reputation, pigs are naturally clean animals. They designate separate areas for eating, sleeping, and waste—if given enough space.

5. What do pigs eat?

Pigs are omnivores and eat a varied diet, including vegetables, fruits, grains, and occasionally small animals or insects. Domestic pigs are often fed commercial feed.

6. Why do pigs root (dig with their snouts)?

Rooting is natural behavior for pigs—they do it to search for food, explore their environment, and keep their snouts strong.

7. Can pigs swim?

Surprisingly, yes! Pigs are capable swimmers, and some wild pigs (like the Babirusa) are known to swim between islands.

8. How many piglets can a sow have?

A sow (female pig) can give birth to 8–12 piglets per litter, and some breeds may have even more.

9. Do pigs make good pets?

Miniature pig breeds (like potbellied pigs) can be good pets if given proper care, training, and space. However, they require long-term commitment due to their lifespan.

10. Why are pigs important to humans?

Pigs are a major source of meat (pork, bacon, ham), provide leather and medical products (like insulin), and are used in scientific research due to their biological similarities to humans.
