We would like to breed our gilt about a week after the state fair. Would starting matrix before the fair keep her for going into heat while at the fair. If there are any other tips to keep her from going into heat from the stress that would be appreciated. Thanks

That should work however I think it recommends females be on it for 10-14 days and then they won't come in heat until 4-6 days after you take them off of it so those would be things you would have to consider.
