Question: I have a gilt that I showed last year. I breed her to a boar on November 25, 2009. Now I know that a pigs gestation is three months, three weeks and three days. I have looked at many gestation tables and they all say that she will have her pigs on February 19 2010. I was just wondering if this was the correct date or if she is really going to have them in March.

Answer: Katie,
 
Thank you for your question.
 
You are correct, the length of gestation in swine is 3 months, 3 weeks, and 3 days, or a total of 114 days.
 
So, if your gilt was bred on November 25th, 114 days from then would be March 19, 2010.
 
Thanks again,
