Understanding Stress in Sows

Introduction to Sow Stress

• The video discusses issues related to nervous or stressed sows, building on previous discussions about constipation and appetite problems.

Causes of Nervousness in Sows

• Nervousness is particularly common in first-time sows due to their unfamiliar environment after being moved from a cage where they spent over 100 days.

• Factors contributing to stress include walking on new flooring, entering unknown maternity facilities, and being placed into unfamiliar pens.

Behavioral Responses to Stress

• Improper handling can exacerbate stress; aggressive treatment leads to fear responses such as refusal to walk and attempts to escape.

• First-time sows may exhibit behaviors like biting bars or trying to leave the pen, which are signs of significant stress rather than nesting behavior.

Recommendations for Reducing Stress

• It is advised not to move first-time sows alone; instead, experienced sows should accompany them for reassurance during the transition.

• Utilizing older sows helps instill confidence in younger ones. Communication between the animals can ease anxiety during movement.

Handling Nervous Sows

• Workers must be trained and sensitive when handling nervous sows. Knowledge of animal behavior is crucial for effective management.

• If a sow remains stressed despite preventive measures, administering a sedative (e.g., azaperone via intramuscular injection) can help calm her down.
