Another voice saying “DON’T INDUCE!!”
I honestly can’t imagine why this would be your vet’s first thought.
I think antibiotics are the way to go – the only way I would think about inducing would be #1) if all the criteria were met (milk is let down, cervix open…and one more which I’ve already forgotten – at least 310 days gestation, isn’t it? Someone help…) and #2 if ultrasound reveals the ambiotic fluid is funky.
Again, I would really question a vet’s experience in repro if “induce” is the first thing that comes to mind without even an ultrasound or a trial of antibiotics.
Is this your regular repro vet? Do you have another repro vet you could question or is there a vet teaching hospital nearby you could call and grill?
I had a mare that started leaking “milk” in month 10 – WAAAYY before her due date or even before Day 300. We started antibiotics and around Day 330 she delivered a healthy filly. The non-pregnant horn was VERY funky looking (like cooked ground beef or something) and you could see where the infection had started. Actually, I was lucky it was in the non-pregnant horn – other wise the mare probably WOULD have lost the pregnancy.
But until you have a reason to panic – don’t.
