Worming dairy cows

[it's not over]

Is there any advantage to worming cows at drying off time,would 1st calf heifers do any better with worming at drying off. Would it only reduce the cows natural immunity to worms . Never wormed cows before or seen the need

Think there was a campaign a few years ago ( I assume by someone selling wormer ) that there were benifits.
You could, Get the vet to do some worm counts.
and / or Select (say ) 10 heifers coming up to drying off.
Worm 5. Don`t worm 5
Compare their weight gain when dry , milk yields, fertility etc etc over the next 6 months
Put your results on TFF

I worm all dry cows and i/c heifers before they calve. Its a long season, so may as well start them off with a clean bill of health, for all it costs.

We get a milk test done every autumn, most years it says no need to worm, this year it did.so we did. Cows are mainly in milk at that time but we wormed before we started service (obviously tied to a more expensive nil milk withdrawal wormer).

Do them all with levafas at dry off.

I use ivermectin at drying off. For lice/mange and worms. So cheap now. Also fluke them

Is that allowed? I thought pour on ivomec wasn't licenced for dairy cows in any stage of lactation.

think it’s ok if more than 60 days before calving

Its really not aloud. Sorry. Just be careful, the tests are getting far more sensitive
