Pulling calves off cows to bring into heat

Postby Jeanne - Simme Valley » Thu Jan 04, 2018 8:08 pm

For years, Universities have recommended pulling the calves off the cows for 48 hours (I believe) so the cow will come into heat.
So, I have a set breeding season. My calves would be ?? potentially a month old to 2 months old. Doesn't this screw up the calf??? not getting to milk for 48 hours, then gorge themselves when they get back with dam???
There is a post about a cow coming in heat twice in 1 week and he said he pulled the calves. That is what brought up this question. I always thought it was a dumb move, although it makes sense it would trigger their hormones big time.
Another question. If stripping the calf off triggers the cow to come into heat, is it a GOOD heat. Will she settle?

Jeanne,

The heats are viable and conception is not compromised. Pulling the calf kick starts the hormone production to begin follicular development.

I don't see any harm coming to the calf.

I am still in question to the health of the calf. Calves at that age only have been consuming mom's milk and some hay/grass. Depriving them of milk for 48 hours would screw up their gut. IMO

I don't do it. I had one cow this winter that did not cycle with a calf on her. I used the 7 day CIDR protocol and she cycled.

Seems more common in europe. Im not really set up to try it. If there is water available - calves are usually trying it pretty early on though.

Is that for AIing or some thing? What's wrong with just letting mother nature do what it does?

Yes, it is to group your cattle up for AI breeding (or could be used for natural if you have enough bull power).
I think you could think of it as a cheap way to synchronize.
I have never contemplated doing it. As I implied, I think it would be poor management for the calves.

Not my idea of the way to do it but maybe for some it would work. We try to have a 60 day window both spring and fall. The calves are 75% born within 30 days, so I don't get too excited about it. Since we sell in groups mostly, we will have 2 or 3 groups of similiarly sized calves to go at a time. And we held a bunch this year and will try shipping them bigger in Jan or Feb. to see if prices will come up a bit. Not sure if we will like this but want to try it.

Don't seem to have much problem getting most of the cows to come in heat in that 30-60 day window... We mostly will move them to a pasture that has good grass in the spring, they seem to get "flushed" with the green growth, and come in heat and breed..... the one fall place has stockpiled grass and they are coming in heat now, on it. No hay or anything except mineral because there is 6 months growth there to work on. If we get snow or anything we will feed hay but unless it is buried, they often will prefer to nose through for the cured grass.

In my opinion if you want to sync cattle use a cidr, ive seen that calf pulling tried, I wasn't impressed just made for alot of uncalled for noise.

Good to know. It has been suggested but never tried it. Now I won't.

I've never liked the idea, I would have thought heat detection would be difficult with them all bellowing and concerned for their calf, or do they come in season after the calves are returned to them?

Ken - waiting for an answer on that one. I don't know. I never liked the idea either.

Not to mention what it may do to milk production or the possibility of mastitis.

When I cut and tag my calves I leave them in the pen for 24 hours or so. Several cows go into heat within a couple days of doing that. I leave them penned and let them out one at a time so I can match cow and calf tags. But I didn't see my cows more than once a week.

BINGO!!! May not be a major problem, but it is a potential problem, so why add to any stress?
