Gilt Heat

Postby floridapigs » Wed Nov 30, 2011 6:19 pm

Please help! I have a gilt came in first heat fine, 21 days later back in heat, third heat hasnt come. I am needing her bread around the middle of the month. We have had hot days followed by rain and cold. Will the weather affect her cycle? What can I do? Thanks! :?

Gilt Heat

Postby mtbkmom » Wed Nov 30, 2011 6:35 pm

This time of year it may have more to do with decreased hours of sunlight---shorter days---longer time between cycling. Some people put their gilts in barns with lights on for a specified period of time/day to bring them back to 21 days. I don't breed winter time so have not experienced this myself---just have read info on this blog about it.

Have you tried to "flush feed" her the week before she comes into heat?

Well I got her flushed and she came in yesterday evening! I picked up semen from Southern Advantage this afternoon, first dose is in her! Thank God for them. I would have missed this cycle if not for them. Thanks for the advice Gil!!!!! :lol:

Gilt Heat

Postby mtbkmom » Thu Dec 15, 2011 8:02 pm

It's when you normally feed 4-5 pounds per days, but 2 weeks (or 1 week) before your projected date for breeding you start feeding like 6-8 pounds/day. Make them think things are more than good and their brain goes nuts and brings them right into cycle like they should.

We usually go with 14 days flush feed coinciding with 14 days of matrix and move them into our barn (change in environment) around day 12 of matrix so we are tripling up our chances of getting our sows/gilts to cycle and when we want them to and then we also followup with PG600 on day 14 or 15 (depending on delivery dates). It has worked with all of our gilts except 2 over 3 years (6-8 gilts/sow herd per year). We do not have very many litters/year so we can't afford a screwup on our part.

Looking back our 1 sow was probably standing as we started matrix so it didn't work and she came in 21 days after starting matrix--AI'd on day 9/10 with semen...didn't take. Our second gilt just did not breed after 3 very closely timed cycle history/behavior--she is no longer with us.

Flush feeding

Postby Gilbertowner » Mon Dec 19, 2011 2:35 pm

on the ones we know will come in we add 1 to 2 cups of pecans to their feed per feed to help with the vit/mins (at least 1 wk before they should cycle)

It sounds like the weather knocked her off her heat cycle. If you want her bred buy some PG600 and inject her with 1 dose and that should knock her back in heat within a few days. Some people say before you breed to wait a heat cycle after using PG600 to insure larger litter sizes. In my experience it doesnt make a big difference.
