We have a lovely boar in with our gilt at the moment, he wasnt shy at all!!! Unfortunately Margot has come back in to season 3 weeks later, how long would you keep trying for? And how long are gilts in season for?

well i'd keep letting him try for a few months

and about 3 days

Was she mated almost immediately after introduction?  If so she may have been a bit too late for fertilisation, even though standing for the boar.

[Ann and Rob]

She was mated within ten minutes!

I would give him a couple of months. When my boar goes on holiday he usually stays a minimum of 6 weeks. I have heard a few people say this year that they are having fertility problems and sows not catching for 2 or 3 cycles so you need to be patient.

[Marches Farmer]

Gilts may well accept the boar over 3 or 4 days, but will be at peak fertility for only around 12 hours in that period.

Thank you for your comments and we will be patient

We put one of our sows, Daisy, in with our boar just before we had the heavy snow. I think this might have put him off a bit as she didn't get in pig. Three weeks later he got down to business and she's just passed through the next season with no signs so job's a good un. So she's been with him for three cycles.

our pig vet told us that with rare breeds of any animal - ie older breeds, that haven't been 'tampered with' there was more of a chance for fertility rates to drop ever so slightly over winter.   More or less guaranteed fertility would be with the more modern commercial breeds.
