What about ivermectin? If you have cattle, surely you can get the pour on type? I know that the folks here don't use it much for a dewormer, but it still might help with the mites. There's also the benefit of it not having any unintended beneficial bug kill. Just a thought.
We do have some left from last year. It is also no longer available without a vets prescription! The cattle didn’t like it much, so I was worried about it irritating her more delicate skin...
We are having to be very careful in rationing our antibiotics, and won’t have access to the basic vaccine for sheep and injectable selenium we give the ewes before lambing either (we live in a very selenium poor area, and without it the lambs are frequently born with leg and jaw defects despite having it in the feed and in the mineral and salt blocks)
We can’t afford having the one large animal vet to come to our farm... it’s 4 hours of driving, followed by 2-4 hours of ferries (the route changes through the day depending on time) it’s a couple thousand for the farm visit, plus the two days of traveling, plus any treatment and examination x150 ewes... we would have suitable accommodations for his overnight stay though.
If he insists on examining any sick lambs before treatment, by the time we get the vet here it will probably be gone already. We lost 5 lambs last year (that were born alive but didn’t make it). It will be tragic but interesting to see how many we lose this year without access to basic medications we would normally have on hand.
I understand the changes and reasons for them... to stop irresponsible and unnecessary prophylactic use of some medications. But completely preventing access to them and not having any solutions for small farms that can’t afford a vet on retainer feels like a push towards eliminating all but the giants in agriculture. And there’s my rant for the year!
Sorry I digressed a bit there but this problem is very frustrating, as I don’t want to see animals suffer or die due to lack of access to essential medications, or the Farm to go bankrupt due to vet bills for travel. I really don’t know why no one fought these changes harder when they were proposed!
