Ovivac P / Heptavac P problem!

[J&LMcK]

I bought breeding ewe lambs at the weekend and asked the seller if he'd given them either of the above. Turns out he'd given them their first dose of Ovivac the day before.

We usually use Heptavac on all our breeding stock with the ewe lambs getting their double dose 4-6 weeks apart in the autumn and then everything getting a single jab 4-6 weeks before lambing starts.

What I'd like to know is - can I just start them on the Heptavac system right now with a double dose this autumn? There are only 25 of them and given that I never use Ovivac for anything else I'll have to buy a 100ml bottle, 50% of which will get binned as it doesn't last being opened for 4 weeks! They'll be getting moved onto Heptavac in the long run and I'd rather start now if possible.

Anyone else had this problem? They won't go to the tup till they're gimmers next year as we don't breed with any of our ewe lambs.

just do them twice with Heptavac - will be fine

Aye that's what I was wanting to do.

Phoned the vet to ask advice but they advised to finish the course of Ovivac the now and then double dose with Hepavac in the spring - although I had the impression that they were making an educated guess!

absolutely no reason to do that. 5/7 are the same in the two vaccines anyway
