Farrowing Preparation

The work you put in before your sow farrows determines how smoothly the birth goes and how many piglets survive those critical first days. Farrowing preparation is not glamorous work, but skipping it or rushing through it costs you in dead piglets, sick sows, and the kind of middle-of-the-night emergencies that nobody enjoys. A well-prepared farrowing area and a properly conditioned sow transform birthing from a stressful event into a manageable routine.

Preparation matters because newborn piglets are remarkably fragile. They arrive wet, with almost no body fat, and with limited energy reserves. A piglet that gets chilled, cannot find a teat, or gets crushed in the first hours of life may not recover no matter what you do afterward. The farrowing environment you create either supports these vulnerable newborns or works against them. Temperature, bedding, space, and cleanliness are not minor details but rather fundamental requirements that directly affect survival rates.

The sow herself needs preparation too. Her nutrition in the weeks before farrowing affects her milk production and her strength during labor. Her familiarity with the farrowing area affects her stress level, and stressed sows have more difficult births and are more likely to savage or crush their piglets. Moving a sow to unfamiliar surroundings the day she is due to farrow is a recipe for problems. Moving her a week or more before her due date and letting her settle in produces a calmer mother and a smoother farrowing.

This guide walks through everything you need to have ready before your sow enters the farrowing area, from facility setup to supplies to sow conditioning. Whether you are farrowing in a simple straw-bedded hut or a purpose-built farrowing house, the principles remain the same. Think through the process now, gather what you need, and prepare your sow so that when labor begins, your only job is watching and occasionally helping rather than scrambling to catch up.

Your farrowing area needs to accomplish three things. First, it must keep the sow comfortable enough to lie quietly while nursing without constantly getting up and repositioning. Second, it must protect piglets from being crushed when the sow lies down, either through careful design or through your attentive management. Third, it must provide warmth for the piglets while allowing the sow to stay cool enough to be comfortable. These requirements sometimes conflict, and your setup represents a balance among them.

Farrowing crates, the metal enclosures used in commercial operations, prevent the sow from turning around and limit crushing by creating spaces around the edges where piglets can escape when she lies down. Many small-scale producers avoid crates because they restrict the sow's movement severely and prevent normal maternal behavior. If you choose not to use crates, you need alternative strategies for preventing crushing. Sloped walls or rails around the perimeter of the farrowing pen give piglets escape routes. Ample bedding cushions the impact when the sow lies down. Close monitoring during the first several days, when crushing risk is highest, catches dangerous situations before piglets die.

Temperature management is where most people underestimate what is needed. Newborn piglets need environmental temperatures around 90 to 95 degrees Fahrenheit in their first week of life, dropping gradually as they grow. The sow, meanwhile, is most comfortable at 60 to 70 degrees and will become stressed and go off feed if overheated. The solution is zone heating, where you create a warm microenvironment for the piglets while keeping the overall area cooler for the sow. Heat lamps, heat mats, or heated creep areas give piglets a warm zone to retreat to between nursing sessions. Position heat sources so piglets can move toward or away from the warmth as needed, and so the sow is not directly under the heat.

Bedding serves multiple functions during farrowing. It insulates piglets from cold floors, absorbs moisture from birth fluids and urine, provides cushioning that reduces crushing injuries, and gives the sow material for nesting behavior that helps her settle before labor. Straw is the traditional choice and works well, though it should be clean and free of mold. Some producers prefer wood shavings or chopped straw, which stay drier but provide less nesting material. Whatever bedding you choose, plan on using a lot of it. A deep bed of clean straw costs a few dollars and significantly improves piglet survival.

Cleanliness before farrowing reduces infection risk for both the sow and her piglets. Scrub the farrowing area with soap and water, allow it to dry completely, and then bed it fresh before the sow moves in. Walls, floors, feeders, and waterers should all be cleaned. If you have had disease problems in previous farrowings, disinfection between litters is worth the effort. The sow herself benefits from a bath or at least a thorough brushing before entering the farrowing area, which removes dirt and manure that could contaminate piglets during birth.

Move your sow to the farrowing area at least a week before her expected due date, earlier if possible. Gestation in pigs averages 114 days, often stated as three months, three weeks, and three days, though individual sows vary by several days in either direction. Moving the sow early gives her time to become familiar with the new space, establish where she wants to nest, and settle into a routine before the stress of labor begins. A sow moved to an unfamiliar pen the day she starts labor is anxious, and anxious sows have more complications.

During this pre-farrowing week, watch the sow for signs that labor is approaching. Her udder fills and becomes firm as milk production begins, typically becoming noticeably enlarged three to five days before farrowing. In the final day or two, you may notice milk dripping from her teats. She becomes restless, getting up and lying down frequently, and may begin arranging her bedding into a nest. Her vulva swells and relaxes. These signs help you narrow down when active labor will begin so you can be available to monitor.

Feeding during the final weeks of gestation requires balance. The sow needs adequate nutrition to support both her piglets' final growth and her upcoming milk production, but overfeeding creates fat sows who have more farrowing difficulties. Reduce feed slightly in the final few days before farrowing, as a full digestive tract makes labor more difficult and increases constipation risk afterward. Some producers withhold feed entirely on the day of farrowing, while others offer small meals. Make sure fresh water is always available, as dehydration causes problems during labor.

Assemble your farrowing supplies before the sow is due rather than scrambling when labor begins. You need clean towels, iodine solution for dipping navels, a bulb syringe for clearing airways, obstetrical lubricant, long disposable gloves, a notebook for recording birth times and details, and a working flashlight for nighttime checks. Have colostrum replacer on hand in case the sow has poor milk production or too many piglets for her teats. Keep your veterinarian's emergency number somewhere you can find it quickly.

The sow's condition going into farrowing affects everything that follows. A sow in good body condition with adequate muscle and moderate fat reserves has the strength for labor and the energy to produce milk. A thin sow lacks resources to draw on and may have weak labor, poor milk production, and difficulty recovering. An overly fat sow faces increased risk of farrowing difficulties, may crush more piglets because of her bulk, and often has reduced milk production because fat deposits interfere with udder development.

Vaccinations should be up to date well before farrowing, not administered at the last minute. Vaccinating a sow close to farrowing can cause stress that interferes with milk production or triggers early labor. Work with your veterinarian to develop a vaccination schedule that protects against diseases common in your area. Common vaccines for breeding sows include protection against erysipelas, parvovirus, and leptospirosis. In herds with specific disease challenges, additional vaccines may be appropriate.

Parasite control matters more than many small-scale producers realize. Internal parasites compete with the sow for nutrients during a time when her nutritional needs are highest, and some parasites can infect piglets through the milk. Deworm your sow according to your veterinarian's recommendations, timing treatments so they are effective but not administered too close to farrowing. External parasites like mange mites cause skin irritation that stresses the sow and can spread to piglets.

Watch for signs of illness in the pre-farrowing period. A sow that goes off feed, appears lethargic, or shows discharge from her vulva before labor begins may have a health problem that needs attention. Infections, injuries, or metabolic problems are easier to address before farrowing than during or after. Any sow that seems unwell in the week before her due date warrants a closer look and possibly a veterinary consultation.

Heritage breeds generally require less intensive preparation than commercial breeds because they have been selected over generations for maternal ability and ease of farrowing. A Gloucestershire Old Spots or Large Black sow on pasture often farrows without any assistance, finding a sheltered spot and handling everything herself. This does not mean you should neglect preparation for heritage breeds, but it does mean that simple facilities and minimal intervention often work well. Heritage sows tend to be more careful with their piglets and crush fewer than commercial breeds.

Commercial breeds and their crosses benefit from more intensive preparation because they have been selected primarily for rapid growth and large litter size rather than maternal characteristics. These sows often carry twelve to sixteen piglets, which increases the physical demands of farrowing and the challenges of keeping that many newborns warm and fed. Farrowing crates or very close supervision help prevent the crushing losses that are common with large, heavy commercial sows. The piglets themselves may be less vigorous at birth than heritage piglets, requiring more attention in those critical first hours.

Gilts farrowing for the first time need extra attention regardless of breed. They have never been through this before and may be confused, anxious, or reactive when piglets start arriving. Provide a calm, familiar environment and monitor more closely than you would an experienced sow. Some breeders house gilts where they can see and hear an experienced sow farrowing first, which seems to help them understand what is happening when their turn comes. Expect more variability in behavior from gilts, including a higher chance of savaging or inadequate mothering that requires intervention.

Moving the sow to the farrowing area at the last minute is one of the most common mistakes and one of the easiest to avoid. A sow needs time to settle into new surroundings before she goes into labor. Moving her the day she is due, or worse, after labor has started, creates stress that prolongs labor, increases aggression, and leads to more crushing. Plan ahead and move her at least a week before her expected due date.

Inadequate heat for piglets kills more newborns than almost any other single factor. People see the sow panting and think the area is too warm, not realizing that piglets need temperatures far higher than what is comfortable for the sow. Zone heating solves this problem, but only if you actually set it up and use it. A heat lamp sitting in the corner of the barn waiting to be installed does not help piglets that are chilling right now.

Skipping the cleaning and preparation of the farrowing area sets up problems. Farrowing in a dirty pen exposes piglets to pathogens at their most vulnerable moment. Manure, old bedding, and contaminated equipment harbor bacteria and parasites that cause scours, respiratory infections, and other problems in young piglets. The hour spent cleaning and bedding the farrowing area saves many hours of treating sick piglets later.

Not having supplies ready leads to panicked improvisation during emergencies. When you need lubricant for an internal examination, you need it now, not after a trip to the feed store. When a piglet is not breathing, you need the bulb syringe immediately, not after you find it buried in a drawer somewhere. Assemble your farrowing kit in advance, check that everything is present and functional, and keep it where you can grab it in the dark.

Overfeeding the sow in late gestation creates fat sows who have more farrowing difficulties, crush more piglets, and produce less milk than sows in moderate condition. The impulse to feed heavily before the demands of lactation is understandable but counterproductive. A sow does not need extra fat going into farrowing; she needs adequate condition and good muscle tone. Save the increased feeding for after farrowing when milk production creates enormous nutritional demands.
