Main Cause of Newborn Pig Mortality
Newborn pig mortality is mainly due to:
- Piglet anemia
- Crushing by mother — Correct Answer
- Cannibalism
- Enteritis
Explanation:
Correct Answer: Crushing by mother
The main cause of newborn pig mortality is crushing by mother. Sows are large and heavy animals, and they can accidentally crush piglets while lying down, especially in the first few days after farrowing.
Prevention
Farrowing pens with guard rails are used to prevent crushing of piglets. Guard rails are fixed along the walls of the farrowing pen at a height and distance that allows piglets to escape underneath while preventing the sow from lying directly against the wall.

Why Other Options Are Wrong
- Piglet anemia: Common condition but not the main cause of mortality.
- Cannibalism: Can occur but is less common than crushing.
- Enteritis: Intestinal inflammation occurs but is not the leading cause.
