How long past the due date have you ever had one go? Got a heifer that's been sprung up huge for the last month and bagged up now. She is two days past due and continues to act normal. I've always heard 10 days either way. I've had cows go over a few days and one that's notorious to go over every time but generally heifers for me have been spot on. What's yalls opinions?
 
I have been told the same thing 10 days either way. This year my heifers didn't start to calve till they were 7 days over. I think mother nature knows more about it then we do if my hiefers would have started on their due date I would of had a bunch of dead calves right now. If you have weather like I have been having maybe the little guys a scared to come out and face this winter weather :???:. Personally I don't think 2 days is much to worry about.
 
Not really worried more aggravated than anything. Lol. Once she calves I can turn out.
 
I've seen calves 14 days or more either way. On heifers usually they are almost done by the due date when bred to a calving ease bull. Non calving ease bulls are usually plus or minus 10 days.
 
So I'm assuming she is not a Limo or GV, or else the resulting gestation EPD, from the mating, would have let you know the over/under. :wink: :lol:

Breed associations should really develop some sort of "turn out" or "aggravation factor" EPD.

Good luck with the cows.
 
Depends on so many different factors. Usually most are within a day or two of their due date but cold winters ,bull selection, etc. can all vary outcomes.

With my Gv's I have found that the most accurate chart to use on gestation for them is a Holstein one, it is usually dead on. But would make them all a week early or calving on their exact due date when compared to a Gv gestation chart . :wink:
 
I think it depends on the female as well as the bull. Just because the bull is calving ease doesn't necessarily mean they will be early or on time. The genetics of the cow would come in play also I believe? This particular heifer is out of a cow that was always late on her date usually 8-9 days regardless of what she was bred too.

You just answered the question yourself with that statement.
 
Well heifer calved today 7 days late. Had to pull it. Was caught at pelvis and calves hip bones. All alive and well. 80lb bull calf out of a calving ease bull????? Some hidden weight in there somewhere!

The cows that calved in Feb here had higher birth weights than the ones in Jan . We had almost 3 weeks of a daily high of 30 below weather in Jan so cattle ate alot and it all went to the calf. There are many factors in regards to higher birth weights. Winter calving the weather usually dictates the high BW when using a calving ease bull. 80lbs would be the norm for my heifers even though they weigh all around 1100 lbs . The Feb calving heifers all had calves around 95 lbs ,out of many different bulls and all calving ease, way more than a heifer should have to deal with. The 2 we had to pull were both bull calves over 100 lbs ,each had a front leg back.
 
Yeah she had a leg back also. But just couldn't get it done without my help. She is around 1000 lbs or better. But this bull calf came with some thickness. But all is well! :-)
