Pregnant pigs, also known as sows, typically weigh around 90 kg during pregnancy. Around 90 kg, though this can vary based on breed and overall health. Sows should maintain a good body condition, neither too thin nor too fat, to support the pregnancy and ensure healthy piglets.

As the due date approaches, signs of farrowing include restlessness, nesting behavior, and milk production. Sows should be moved to a farrowing crate or pen to ensure a safe and controlled birthing environment.
