Do Pigs Eat Their Babies? An In-Depth Look

The idea that pigs eat their own babies, known as “savaging,” is a topic that fascinates and horrifies many. While this behavior is rare, it does occur under certain circumstances. Understanding why this happens and how to prevent it is crucial for farmers and anyone interested in animal behavior.

Why Do Pigs Eat Their Babies?

Several factors contribute to this disturbing behavior:

Stress: High levels of stress in sows, particularly first-time mothers (gilts), can lead to aggressive behaviors, including savaging. Stress can be induced by environmental changes, social stress, or even the birthing process itself
Nutritional Deficiencies: Inadequate nutrition, especially a lack of essential vitamins and minerals, can drive sows to eat their piglets. Ensuring a well-balanced diet rich in proteins, fats, and carbohydrates is vital
Environmental Factors: A harsh or unfamiliar environment can increase stress levels in sows. It’s important to provide a calm, comfortable, and familiar space for farrowing
Pain and Discomfort: Pain during and after farrowing can lead to aggressive behaviors. Providing appropriate pain relief can help reduce the risk of savaging
Clumsiness: Some sows may accidentally injure or kill their piglets by stepping on them. In such cases, the sow might eat the injured or dead piglet
Protective Behavior: In some instances, sows might eat a sick or weak piglet to protect the rest of the litter from disease or predators.

How to Prevent Savaging

Preventing this behavior involves addressing the underlying causes:

Create a Stress-Free Environment: Keeping the farrowing area quiet and stress-free is crucial. Limiting the number of visitors and avoiding sudden changes can help keep the sow calm.
Provide Proper Nutrition: Ensure that sows receive a well-balanced diet that meets all their nutritional needs, especially during pregnancy and lactation .
Use Farrowing Crates or Pens: Farrowing crates can help prevent accidental crushing of piglets by restricting the sow’s movements. Providing nesting materials can also promote positive maternal behavior and reduce aggression.
Supervise Farrowing: Close supervision during and after the birthing process can help quickly address any signs of aggression or distress in the sow.
Reduce Pain: Administering pain relief to sows during and after farrowing can help reduce aggressive behaviors linked to discomfort).
