Don't Let Their Size Fool You
Pigs may not have the imposing size of cattle, but they are responsible for a significant number of agricultural injuries each year. Swine are strong, fast, and have sharp teeth capable of severe bites. Boars can be genuinely dangerous, with tusks that cause devastating wounds. Whether you are raising a few pigs for meat, managing breeding stock, or working with a commercial operation, knowing pig behavior and proper handling techniques is the key to staying safe.
This guide covers the hazards of working with swine and protocols for safe handling.
Understanding Pig Behavior
Natural Instincts
Pigs are reactive and defensive when they feel threatened, with strong survival instincts that kick in quickly. They are group-oriented animals but establish clear hierarchies within the group. One trait that makes pigs both fascinating and challenging is how quickly they learn. They pick up good behaviors and bad ones alike, they remember handlers and past experiences, and they can become genuinely difficult to work if handled poorly early in life.
Social Behavior
Introducing new pigs to an established group always triggers challenges. Dominant pigs can be more aggressive during mixing, and the resulting stress leads to fighting. Sound plays a major role in pig behavior as well. Distress calls can trigger reactions across the whole group, and a screaming pig can cause panic in both the handler and the herd simultaneously.
Defensive Behavior
When threatened, pigs may bite (with serious injury potential), charge, knock handlers down, crush them against walls, or trample them. Never assume a pig will simply run away from you, because cornered pigs often choose to fight.
Hazards of Swine Handling
Physical Hazards
Pig bites are no minor matter. They can bite off fingers, and bite wounds are severe and prone to infection. Even "friendly" pigs may bite when stressed. Crushing injuries are equally dangerous, as pigs can pin handlers against walls or in corners, may lie on handlers who fall in pens, and are particularly hazardous in confined spaces.
Charging presents another serious risk. A charging sow or boar can knock an adult down and may continue the assault after the handler is on the ground. Protective mothers are especially dangerous in this regard. Boar tusks can slash, gore, and hook, creating wounds that can be life-threatening. Even trimmed tusks retain enough edge to cause real injury.
Infection Hazards
Pig-related wounds carry elevated infection risk. Common zoonotic concerns include leptospirosis, streptococcal infections, various skin conditions, and secondary wound infections from any bite or scratch. Treat every pig-inflicted wound seriously and seek medical attention promptly.
General Safety Principles
Facilities
Proper swine facilities make handling dramatically safer. Pens need non-slip flooring, adequate lighting, gates that swing both ways, and escape routes for handlers. Alleys should be the appropriate width so pigs will not turn around, and curves encourage forward movement. Loading chutes need proper slope to keep pigs moving without balking.
Boar pens deserve special attention with double fencing for added security, gates that allow handler protection, and designs that require no entry for routine care when possible.
Handler Positioning
Four rules apply every time you step into a pen with pigs. Always have an exit route, never underestimate any pig regardless of size, be especially cautious around sows and boars, and never turn your back to dangerous animals.
Handling Tools
The basic toolkit for moving pigs includes rattles or paddles for directing movement, hurdles for blocking and guiding, and snares for restraint when you have been trained in their proper use. Never strike pigs; instead use tools for blocking and guiding. Keep your tools between you and the pig at all times, and sorting boards allow you to retreat while protecting your legs.
Moving Pigs Safely
Understanding Movement
Pigs move away from pressure applied at the hindquarters and tend to follow other pigs. They move best in groups of five or six and will stop to investigate anything novel in their path. Working with these natural tendencies rather than against them produces far better results.
Moving Techniques
In group settings, use solid-sided alleys, apply gentle pressure from behind, let pigs move at their own pace, and avoid rushing since that only creates panic. When moving a single pig, keep it in front of you, direct movement with the angle of your sorting board, move slowly and deliberately, and try to anticipate where the pig will go next.
Avoid electric prods except as an absolute last resort for welfare purposes. Never strike pigs, avoid mixing unfamiliar pigs during moves, and do not overcrowd alleys and ramps.
Loading and Unloading
For loading, use non-slip ramps with appropriate lighting inside the trailer. Do not rush the process because pigs need time to investigate their surroundings. Position board handlers at the trailer entrance to guide movement. For unloading, let pigs come out on their own initially, watch for animals that want to turn back, and be aware that newly arrived pigs will be stressed and potentially reactive.
Working with Sows
General Sow Safety
Even smaller sows can be dangerous, and the risk increases significantly during farrowing. Sows become protective of their piglets and may be defensive about any perceived threat to the litter.
Farrowing Safety
Working around sows with piglets requires careful awareness. Piglet squealing triggers a strong defensive response in the sow, and the confined space of a farrowing crate can trap handlers in a bad position. Sows may bite or snap with little warning.
Move calmly and predictably around farrowing sows. Avoid making piglets squeal if at all possible, have your escape route planned before you start working, and consider the sow's confinement level as part of your safety assessment.
Processing Piglets
Common piglet processing tasks include tail docking, castration, iron injections, and ear notching or tagging. During these procedures, minimize piglet distress sounds as much as possible, have help available to remove piglets from the sow's line of sight, watch the sow's behavior constantly, and take a break if the sow becomes agitated. Pushing through when a sow is upset puts everyone at risk.
Working with Boars
Boar Danger Level
Boars represent the highest risk category in swine operations. They use tusks to slash and gore, may continue an attack on a downed handler, and can cause fatal injuries. Aggression increases during breeding season, making an already dangerous animal even more unpredictable.
Handling Boars
Use gates and barriers to manage boars whenever possible. Never enter a boar pen unnecessarily, and if entry is required, have an escape route planned and backup personnel standing by. For any procedure requiring direct contact, have a second person as backup, consider sedation, and never work alone with a boar. Be prepared for sudden aggression even from boars that have been calm in the past.
If a boar attacks, try to get a barrier between you and the animal. Climb over a fence if possible. If you cannot escape, fight back targeting the nose, which is the most sensitive area. Call for immediate help and seek medical attention for any wounds, no matter how minor they appear.
Restraint Methods
Physical Restraint
The snout snare works by using the pig's natural tendency to pull back, creating self-restraint. This technique requires training to perform safely and is not suitable for extended restraint. Holding small pigs in a cradle position also requires practice, and you should watch for signs of stress throughout.
Pen Restraint
Corner the pig using a sorting board, push it into the corner, and have a second person work from the other side of the board. This approach is efficient for quick procedures like vaccinations and does not require specialized equipment.
Mechanical Restraint
Head gates and restraint chutes are available for commercial operations and represent the safest option for many procedures. Mechanical restraint reduces stress on both the pig and the handler, making it a worthwhile investment for operations that process pigs regularly.
Zoonotic Concerns
Disease Transmission
Three zoonotic diseases deserve particular attention around swine. Leptospirosis is caused by bacteria in urine that enters the body through wounds or mucous membranes. Streptococcal infections can result from serious wound infections caused by bites. Swine influenza can infect humans, making respiratory precautions relevant during outbreaks.
Prevention
Protect yourself by washing hands thoroughly after handling, cleaning all wounds immediately, reporting unusual illness to your healthcare provider, keeping your tetanus vaccination current, and wearing boots that can be sanitized. These habits should be automatic every time you work with pigs.
Youth and Swine Projects
4-H and FFA Safety
Selecting the right animal is the first step in a safe youth swine project. Barrows (castrated males) are safer than gilts, and boars should never be used for youth projects. Select animals with calm temperaments above all other traits.
Supervised handling should be required at all times, with age-appropriate responsibilities and solid emergency response knowledge. At shows, youth should maintain control of their animal, watch for other show pigs in close proximity, and know the show facility layout before entering the ring.
Bottom Line
Pigs deserve genuine respect regardless of their size. A severe bite can happen from any pig, and the infection risk that follows makes even minor wounds a medical concern. Boars are outright dangerous, so minimize direct handling and use facilities designed to keep barriers between you and the animal.
Sorting boards should be your constant companion when working pigs. Always have one as a barrier and never allow yourself to be cornered in a pen without an escape route. Move pigs slowly because panic creates danger for everyone involved, and watch sows with piglets closely since maternal aggression is real and can escalate without warning.
Zoonotic disease is a genuine concern with swine, so wash your hands after every interaction and protect any open wounds before entering a pen. Youth projects require consistent adult supervision because pigs can injure children quickly and without the warning signs that larger livestock tend to give.
