I have a sow we breed once a year. She is approximately 2 1/2 years old. Her last litter was July 23. She went into heat 21 days after weaning, and has been in heat every 21 days since, on the dot. I was planning on breeding her March 30. She did not come into heat March 8 like she was supposed to. What could be the reason for this? This is the first time she hasn't.
