Problem Overview

Stillbirth Problems in Sows: Causes, Farrowing Risk, and Prevention addresses an elevated number of stillborn piglets in late-gestation and farrowing sows. Common field signs include repeated stillbirths within litters, more deaths late in the birth order, long birth intervals, weak liveborn piglets or a herd-level rise in stillbirth rate. These signs describe a production problem, not a final diagnosis, and they should be interpreted together with age, timing, spread, environment, feed and herd history.

The first task is to separate an individual event from a repeated herd pattern. One affected animal may need prompt individual care, while a recurring batch problem usually points to a wider issue in health status, nutrition, facilities, pig flow or daily execution. Changing products without locating that pressure often creates only temporary improvement.

This guide is intended for practical farm management and product communication. It does not replace laboratory diagnosis or veterinary care. Veterinary medicines must follow local regulations, approved product labels, withdrawal periods and veterinary guidance.

1. Why It Matters

The main commercial consequences are fewer pigs born alive, lower pigs weaned per sow, greater labor demand and reduced value from gestation and farrowing capacity. The cost is therefore larger than the visibly affected animals. Delayed growth or reproductive output also reduces the efficiency of buildings, labor and feed already committed to the group.

Variation is an important warning signal. When only group averages are reviewed, a growing tail of poor-performing animals can remain hidden. Farms should track the distribution of results, removals, treatments and repeat cases, not only the final average.

For distributors, the most useful conversation begins with the farm pattern: when it started, which animals are affected, what changed beforehand, what has already been tried and how long the response lasted. This creates a clearer route to the right combination of veterinary, nutritional and management support.

2. Main Causes to Check

Prolonged farrowing

As farrowing continues, placental separation and reduced oxygen can increase intrapartum loss, especially for piglets born later. Farms should compare affected and stable groups before deciding whether this factor is central to the case.

Large litters and uterine crowding

High total born can increase farrowing duration, low birth weight and competition before birth. Farms should compare affected and stable groups before deciding whether this factor is central to the case.

Sow condition, parity and fitness

Very old, over-conditioned, lame or poorly fit sows may have greater farrowing difficulty. Farms should compare affected and stable groups before deciding whether this factor is central to the case.

Heat, disease and fetal compromise

Late-gestation heat stress, reproductive disease and placental problems may increase fetal loss or reduce piglet vigor. Farms should compare affected and stable groups before deciding whether this factor is central to the case.

Supervision and intervention

Too little supervision can delay help, while unnecessary or unhygienic intervention can injure the sow or piglets. Farms should compare affected and stable groups before deciding whether this factor is central to the case.

3. Practical Assessment

Record total born, born alive, stillborn, mummies, birth order, farrowing duration and assistance for each litter.

Necropsy or examination can help distinguish fetal death before labor from intrapartum death and redirect the investigation.

A simple investigation sheet should include animal age or parity, affected percentage, feed and water intake, temperature and ventilation, recent movements, diet or ingredient changes, vaccination history, treatment response and mortality. Photographs, production records and correctly collected samples make remote technical communication more useful.

Cases showing a sow actively straining without progress, abnormal bleeding, collapse, severe distress or a sudden cluster of stillbirths across the herd require prompt veterinary assessment. Routine product discussion should stop when animal welfare, a notifiable disease or a rapidly developing outbreak may be involved.

4. Recommended Program

Build the program in layers. First, stabilize urgent animals and identify whether veterinary treatment or diagnostics are required. Second, correct water, feed, temperature, hygiene, stocking and workflow problems. Third, use nutritional or feed-safety products only for the role they can reasonably support.

Sow Reproductive Health Feed Additive can support a planned reproductive-nutrition program before farrowing after condition and ration adequacy are reviewed. Product use must follow the approved label, complete ration, local regulations and professional guidance appropriate to its category.

Multivitamin Feed Additive can support vitamin intake during late-gestation stress periods. Product use must follow the approved label, complete ration, local regulations and professional guidance appropriate to its category.

Refined Cod Liver Oil Powder (Vitamin AD3E) provides vitamin AD3E nutrition where the complete diet and local product guidance indicate a need. Product use must follow the approved label, complete ration, local regulations and professional guidance appropriate to its category.

Mildew Solution (DCR) – Mycotoxin Binder & Degrader supports feed-safety risk control when ingredient or storage conditions raise concern. Product use must follow the approved label, complete ration, local regulations and professional guidance appropriate to its category.

These products should not be presented as a fixed bundle for every farm. Select only the components that match the identified pressure, then define what result will be measured and when the program will be reviewed.

5. Management Priorities

1. Train staff to monitor birth intervals and intervene according to a veterinary protocol.

Assign responsibility, define an observation period and record the response. A correction is useful only when the team can confirm that it changed animal behavior, clinical signs or production performance.

2. Manage sow condition, heat and movement before farrowing.

Assign responsibility, define an observation period and record the response. A correction is useful only when the team can confirm that it changed animal behavior, clinical signs or production performance.

3. Use records to separate individual-sow events from a herd-level trend.

Assign responsibility, define an observation period and record the response. A correction is useful only when the team can confirm that it changed animal behavior, clinical signs or production performance.

After the immediate case, review the previous and next batch. If the same pattern occurs at the same stage, the solution must include prevention before animals enter the risk period. All-in/all-out flow, cleaning, drying, stable sourcing and staff consistency often matter as much as the selected product.

6. Suitable Customers

This guide is suitable for commercial pig farms, family farms, breeding or nursery units, feed distributors, veterinary-product distributors and animal-nutrition suppliers. Larger farms can use it to standardize investigation and records; smaller farms can use it as a practical checklist before purchasing another product.

Distributors should avoid promising one universal solution. A professional recommendation explains what the product is expected to support, what management correction is required, when veterinary diagnosis is necessary and which result should be checked afterward.

7. Application Suggestions and Precautions

Do not combine several veterinary medicines or feed products simply because the case is severe. More products do not guarantee a better result and may make it difficult to identify what worked. Use veterinary medicines only for approved indications and under local professional guidance.

Feed additives support nutrition, stress recovery, gut condition or feed safety according to their formulation and label. They do not directly diagnose, prevent or cure infectious disease, and they do not replace clean water, appropriate diets, vaccination, biosecurity or necessary veterinary treatment.

Keep a written record of the starting condition, selected actions, dates, product use, clinical response and production result. Review failures openly. A repeat problem is valuable information because it shows that an underlying pressure remains.

FAQ

Are all stillborn piglets lost during labor?

No. Some die before labor; examination and records help distinguish the timing.

Do large litters increase risk?

They can increase farrowing duration, low birth weight and late-birth-order risk.

Can more intervention reduce stillbirths?

Only timely, trained intervention helps; unnecessary intervention can cause harm.

Does sow condition matter?

Yes. Over-conditioning, poor fitness and parity can influence farrowing.

When should herd diagnostics begin?

When the stillbirth rate rises consistently, clusters by batch, or occurs with abortions or other disease signs.
