How close to calving? (Photos)

We like to use udder development as a good indicator of how far along a cow is.

Keep in mind a few things:

  1. Every cow develops differently. The heifer in these pictures did not make up as much edema as heifers often do, so she’s kind of a good mix between heifer and cow.
  2. Cows that have calved before are very different from heifers. You may not see much change in the udder until a few days before to a day after calving.
  3. Heifers tend to calve early, but any cow can calve several days in one direction or another of her due date. I’ve seen calves born two weeks early or over two weeks late with guaranteed breeding dates (meaning not just that a bull got them on a different heat).
  4. Be sure you have the right calving date! It’s easy enough to get dates mixed up. Keep records and check a gestation calendar to double check your math. You can find one on this page: Breeding Your Cow
  5. The “Medicine Box” area of this website has many sections relevant to calving, particularly: Calving PreparationΒ and Medicine Box
  6. Focus on what is important for this calving. For example, if you have a heifer, you may want to read up on and be prepared for pulling a calf, as a heifer may need more help than a mature cow. If your cow has had multiple lactations or is a high producer, read up on milk fever and ketosis.
  7. Don’t forget to prepare for a baby, as well. Sometimes, we get so excited for our cow to calve, we forget about preparing for the calf! (And what to have on hand in case the calf is sick!)

A note on the photos below. The Jan 1 photo is after little man (her baby) nursed. He was born in the night and when we peeked out the window about 7am, he was curled up sleeping, dry and full. So that is a post-milking photo. πŸ™‚

Many people may ask about “the pins”. First, you need to know what they are! Basically, “hooks” are the FRONT (closer to head of animal) part of the hips and “pins” are the BACK (closer to tail) part of hips.

Okay, so now, why are “pins” important? Well, several hours (less than 24) before a cow calves, the pins will “drop” which means they will loosen up substantially in preparation for calving. Again, basically that means she’s getting ready to be able to push a 50-100 pound calf out her rear end!

Note, pins are NOT a good reference (like udder) for general indications of how far along a cow is. Yes, her pins WILL start to relax a little bit, but what you think is relaxed may be no where close to when she actually calves. You should be able to fit your hand down into the spot between a pin and the tail head when she’s really close:

Do I find pins a good indicator for beginners to know when their cow is soon to calve? No. I find that so many cows are different, I mean recently I saw a cow that looked like Rosalind post-calving (Jan 1 photo) and she waited several more days to calve! Instead, I like to include “pin development” on my list of things to watch (check out the full list on the Calving Preparation page).

This last calving was my first time photographing and marking development of the pins. The photos are more difficult to take versus seeing the cow live, but they can give you an idea of how even on Dec 29, she had not developed a huge amount in the pins. That look was where she had been for almost two months, and I attribute it to the fact that she was a tad on the thin side when she arrived early November to our home.

Another example:

    Hi! I have the same questions as the rest of you! It’s my first having a calf, very
    nervous! We bought her knowing she would have a baby April 24 if the AI took.
    If not, 3 weeks from now (she was put in with a bull). We have her pinned up just
    in case it is today. How long should I wait to put her back with the others if she is
    not due for another 3 weeks? I have been checking out all the signs of birthing, she
    has a few signs, but not much is happening. Just want to make sure our little Annie
    is ok!

    1. Is she showing signs of being due very soon? If not, she probably took to a later breeding date. Cows should not be kept in a pen so small that their movement is limited, but they also should not be out on the open range so close to calving. If you can keep her nearby but in an area she can move around, that would be best. Preferably somewhere you can easily see her.

      If she is a dairy cow, her “signs” of calving should be very obvious – her udder should be large and uncomfortable and tight, her vulva should be large and sloppy, she may be dripping milk or acting weird. There are lots of signs that should make it obvious – if you’re not seeing much, then sounds like you have some time. Feel free to email me some pictures, I can take a look at her and see if there’s anything further I could notice.

    My heifer should be due any time. she is discharging for a few weeks now and starting to bag up .we put her in a pen as the fields are wooded and dont want to have to hunt for . will this hinder her timing for calving ? as she seems to cry for her friends

  3. I bought a bred beef cow back in December of 2016, said it was 5×7 at the time… I’ve been watching!! For ever.. lol, when a cow was said to be bred for 7 months I was told it could be longer than that. I know it’s an impossible question but in this case how long could it have been bred for, is there a chance she is eight months along when I got her? The bag is starting to take shape, there is discharge and the whole pin bone thing is beyond me. Any thoughts of how much longer I may have? Thank you!!

    1. Yes, with beef cows bred to a bull, their due dates can vary widely! Unless the breeding was AI or the farmer took the cow on X day to be bred to the bull and no other day, then you really don’t know the due date. To complicate things further, beef cows don’t develop an udder in the same way that milk cows do.

      If you think she’s just starting to make up an udder, you’re probably 2 to 4 weeks away. The discharge is very normal and very good to see – means she’s progressing in a healthy way!

      Feel the ligament between her pin bones (the back hip bones) and her tail head/spine – right now it’s probably fairly firm. If you want to learn how it changes, feel it a few times and if one day you come out and the pin ligaments are loose like jello, she’s probably very close. If you miss the calving, you should still be able to feel the pins be loose for a little while after calving.

      Waiting is the hardest part of calving!! πŸ™‚

    How much longer. Last week she had a weird slimmy discharge. That stopped. For a week now she has been pawing and rocking when she lays down. And just being different.

    Don’t know exactly due date on mine. We got her already breed. Was told late Nov. She had a slimmy discharge last week but that stopped. She is pawing the ground and rocking when she lays down. Acting weird so now udder is filling up. Nervous she is our first. How much longer.

    1. Discharge can show up on and off for several weeks before calving, it is an indicator she’s doing everything right.

      Pawing and rocking are likely because she is very uncomfortable. The last month or so, the calf grows the most and the cow becomes very uncomfortable.

      Udder filling up happens in the last couple of weeks before calving. Very close to calving the udder usually changes a lot (grows about double in size in one day), also the teats may go from wrinkled to full or even start spraying milk.

      When she’s calving, you may hear her make a lot of noise, have contractions, lift her tail and not put it back down, see discharge with blood-tainted fluid. She may head to the far end of her pen, as far away from people/home as possible (she’s trying to calve in a “safe” quiet location).

      Hopefully you’ll head out soon and see a calf on the ground. If you see her pushing or see feet but nothing progresses over the next 30 minutes or so, you should call a cattle friend or vet to come help assess her.
