Sow won’t cycle

Post by HBV-Showpigs » Fri Nov 30, 2018 8:41 pm

I have a sow that I have been checking daily for the last 30 days. She has shown no sign of coming into heat. This would be her second litter. Her first litter she showed great signs and stood no problem. I need to get her bred in the next two weeks to have her timed right for fair pigs. The other sow that that is with her came in normally and is bred. Any advice would be greatly appreciated.

Some have success using matrix or swine mate plus pg600 shot.

Hopefully you have a teaser boar that you use for heat check. Some sows just don’t respond without a boar.

It's a little late of a response, but Matrix has always helped us get one to show heat strong. They need to be on it 14 days, though. Also, it doesn't regulate the cycle in one that has not been showing well. It just makes it come on hard that one cycle after you take her off it. Adding PG600 after Matrix reduces your chance of conception and litter size. If using PG600 you should breed on the following cycle.

The other thing to consider is her conditioning. Sometimes if you are trying to breed back and they haven't eaten hard through weaning they can lose the conditioning that they need. Her body needs to know it can support a pregnancy.
