Wild heifers

[WiltonRanch]

Anyone find their bred heifers unusually rattled this year? Kinda thought it was just us but overheard auction market guy saying guys are experiencing this.

We just started calving the heifers and they seem normal here so far, at least it looks like it should start warming up.

Calved out 50 so far, quiet and no issues at all!

Our heifers have settled down pretty well. About half calved out. I have noticed that there are quite a few losing hair. Probably lice. I don't think it helps their temperament or mothering ability. We depend on generic ivermectin in the fall for lice control. For some reason not good this year.

I was talking to a buddy the other day about the pour-on not being effective and he agreed. His theory is that product that doesn't meet the quality standards is being shipped to us here on the east coast as he figures that they take us as a push over. I don't believe that is the actual reason but it seems the generic stuff that I am using doesn't seem to do the job as it once did. Is it like the antibiotics and a build up of resistance to the ivermectin is taking place?

Was that Noromectin you're having trouble with? I've used it in the past with no issues but picked up a bottle at Peavey Mart that had water in it - at least a liquid that froze enough to plug the tube and wreck my gun when it was -20C. I guess if you'd used that in the fall on a warmer day you'd never have noticed. I took it back and got a replacement but I don't think they were surprised.

I beleive it was, the last jug I got was Bimectin I think but haven't used it yet.

We used ivomec itself applied November and cows are sure rubbing now. Everyone is finding the same. Vet says it’s more dandruff than anything but judging by missing hair I’d say the stuff didn’t perform. Maybe should retreat with cylene or another mode of action.

My theory is the more you use, the more you have to use....before I got into purebred, my cows seemed OK not to have anything.....when the purebreds came in and had been on a "program", it was very noticeable...damned near naked....when I didn't Ivomec the first year. Had to change quickly.
For a while we could get "Lice Off" and I alternated between the two and seemed quite adequate. But then Lice off disappeared.
Noticed they are scratching lots now, but higher temps and hair will make you do that.
Kinda like hayfields...once you start fertilizing, you had better keep it up....mother nature has her systems and we tend to like to meddle.
Haven't noticed heifers being any wilder this year...but this calving late
April/May on lots of acres does make them a little more heads up...but they seem to get used to me fairly quickly now that I am visiting more than once a week.

We never did our cows this winter either perfecho, lost a little hair but nothing to worry about compared to losing all the dung beetles if you do use it. Still do the weaned calves though.
