Piggery Management Practices for Reducing Mortality
Introduction
High mortality is one of the fastest ways to turn a profitable piggery into a money-losing headache. Whether you’re managing a smallholder unit or a commercial farm, many deaths are preventable.
1. Start with strong biosecurity
Biosecurity is the first line of defense. Pathogens spread fast in pig populations — and one infected animal can infect many. Key actions:
Controlled access: Limit visitors and non-essential traffic. Use a farm gate log and require clean clothing/boots for anyone entering pig houses.
Quarantine new arrivals: Quarantine new pigs for at least 21 days; monitor, record temperatures, and treat any illnesses before mixing with the herd.
Sanitation protocols: Clean and disinfect vehicles, equipment, feeders, and boots. Rotate disinfectants to avoid resistance and follow label contact times.
Rodent & pest control: Implement an integrated pest management plan — rodents carry Leptospira, salmonella and other pathogens that increase mortality.
Water quality control: Test and, if needed, treat water sources. Contaminated water spreads disease and lowers immunity.
Good biosecurity reduces disease outbreaks — the single biggest driver of large-scale mortality.
2. Optimize housing and environment
Stress from poor housing increases susceptibility to disease and death. Aim for comfort, safety, and hygiene:
Proper ventilation: Avoid drafts on piglets but ensure fresh air to reduce respiratory disease and ammonia buildup. Natural or mechanical ventilation should keep temperature and humidity in ideal ranges.
Temperature control for piglets: Newborns need 30–34°C in the creep area during the first week. Use heat lamps or heated floors and monitor regularly. Hypothermia is a major cause of early piglet deaths.
Clean, dry bedding: Replace soiled bedding frequently. Moist, dirty floors lead to skin infections and secondary illnesses.
Safe pen design: Prevent crushing by sows using anti-crush rails and well-designed farrowing crates while balancing sow welfare. Ensure feeders and waterers are accessible, not overcrowded.
Stocking density: Avoid overcrowding at all stages; it raises stress, aggression, and disease transmission.
3. Farrowing & piglet care
Reducing piglet mortality requires attention in the first 72 hours — the most critical window.
Supervised farrowing: Where possible, monitor sows during farrowing to assist with difficult births and reduce stillbirths. Timely intervention reduces trauma and infections.
Colostrum management: Ensure piglets receive colostrum within the first 2 hours — it’s essential for passive immunity and survival. If the sow’s colostrum is inadequate, use high-quality colostrum replacers.
Cross-fostering strategy: Use cross-fostering carefully in the first 24 hours to match piglet numbers to the sow’s teats and ensure even access to milk. Avoid frequent moves which increase disease spread.
Iron and tail-tooth care: Administer iron injections typically within 2–3 days to prevent anemia; clip needle teeth only if necessary and handle with hygiene.
Monitor for crushing and starvation: Keep weak piglets in a warm area and tube-feed if necessary. Use temporary nurse sows for surplus litters.
Small investments in early piglet care yield outsized reductions in pre-weaning mortality.
4. Nutrition & feeding protocols
Good nutrition builds immunity and resilience.
Quality feed: Use balanced diets formulated for each production stage (sow gestation/lactation, starter, grower, finisher). Poor nutrition lowers disease resistance.
Consistent feeding schedule: Sudden feed changes upset gut flora. Introduce diet transitions gradually over 7–10 days.
Water availability: Always provide clean, palatable water — dehydration increases mortality quickly, especially in hot weather or during disease.
Feed hygiene: Keep feed dry and free from molds. Mycotoxins suppress immunity and cause unexplained deaths. Use proper storage and consider mycotoxin binders where risk is high.
Supplementation: Work with your vet to add vitamins, minerals, or electrolytes during stress periods (weaning, heat stress, transport).
5. Health programs: vaccination, parasite control and rapid response.
Prevention and early treatment save lives.
Vaccination schedule: Follow a herd-specific vaccination plan targeting common local pathogens (e.g., porcine parvovirus, erysipelas, PRRS where applicable). Coordinate timing with breeding and farrowing cycles.
Parasite control: Regular deworming reduces intestinal parasite loads that stunt growth and increase susceptibility to disease. Tailor programs to local parasite pressures.
Routine herd checks: Daily observation to spot coughing, lameness, diarrhoea, or off-feed animals. Early detection allows targeted treatment and isolation.
Rapid isolation & diagnostics: Isolate sick pigs immediately. If an unusual pattern or high mortality occurs, collect samples and consult your veterinarian for diagnostics — waiting increases losses.
Antimicrobial stewardship: Use antibiotics under veterinary guidance only and maintain records. Responsible use protects drug efficacy and public health.
6. Record-keeping, training and continuous improvement
Good data drives better decisions.
Record deaths & causes: Track mortalities by age, cause (if known), and location. Look for patterns — e.g., seasonal spikes or pen-specific problems.
Performance KPIs: Monitor mortality rate, pre-weaning mortality, weaning weight, feed conversion, and treatment costs. Set realistic targets and review monthly.
Staff training: Train staff in animal handling, identifying early illness signs, and hygiene protocols. Empower experienced workers to act quickly.
Review & adapt: After any disease event, run a post-mortem review and update protocols. Small process changes often yield big mortality reductions.
Conclusion & call to action
Reducing mortality on your piggery combines prevention, good environment, careful farrowing care, nutrition, and a strong vet partnership. Start with biosecurity and piglet care — those moves give the fastest returns.
