Calving time

[GDR]

Had this calf this morning, had noticed the cow getting close so had put her in and weather was pleasant so all around good deal, just not supposed to start calving till the last half of March. Do recall having a bit of a pen mix up at calving time but the point of the story is I looked her up and she calved on March 20th last year, which by the calendar would have her bred back 13 days later, give or take. I know mares breed well on there foal heat soon after foaling but this is surprisingly quick for a cow.

Just wish they would breed back like that when you are trying to back them up.

Usually there is a sub-fertile heat around 30 days post-calving. To move a cow ahead 70 days without hormone intervention is pretty cool. Maybe keep the bulls a little further away from the calving pasture?

Ya I'm amazed too. We had some nasty weather for calving last year and had everyone penned up a little too tight. Hoping to be able to move the bulls to another yard for spring if I can get my ducks in a row. What my management skills lack, makes for more interesting days on the farm!

At least it's easier to push her back to get in line with the rest of the herd than try and bring her forward (When you want it to happen it doesn't nearly so easily!)

By the calendar should start calving this weekend but had 4 cows calve yesterday and today. 3 out of the 4 cows had twins. Did lose both of one set so not all rosy stories but pretty amazed to have 3 sets in a row, usually only get 2 or 3 sets in a season.

Twins come early. Be ready for a second flush at the second cycle. Also know of a guy who figured one calf in heifer/heifer sets would almost always twin as well. He had a system to figure out which one and could expand his herd in a hurry just because so many twinned!

I always want my nurse cows to have twins so I don’t have to buy so many fosters.... hasn’t happened yet 😂

While we’re dreaming............

I would like my calves to come out guaranteed to suck, tagged, vaccinated, and banded................ hasn’t happened yet either😉

Got the first 4 down now - all heifers.

Last year 2/3 of the crop was bull calves. It's gonna have to change quickly to even out since we have only a handful of cows.

I said to my wife, oh well, look at the money we're saving on bands...

Most years heifers to steers is close to even with steers a bit over. This season so far at 50% done probably 55% steers. Imagine by the end there’ll be 2/3 steers. Heifers come first around here. Who knows. I said that about twins but had first 2 sets of twins other day. In fact a late calving heifer a set. Anyone need an extra calf? She’s caring well for one at least but abandoned the other. If it was a cow I’d try to keep them together but a heifer is best to have just one.

My understanding is heifers have shorter gestation thus earlier and lighter.
Not unusual to see twins 2 weeks early.
One year when I had mostly Simi we had 7 sets of twins from the first 10 cows.
Never looked forward to having twins after that.
I think Oz has an epd for gestation in days for some AI bulls. Helps when selecting for calving ez.
