Calf Due Date:

Remember that this is an estimated due date for your cow. The average length of pregnancy is 283 days, but the range is 279-292 days. Make sure you gather all of your supplies and prepare for calfing before this estimated due date.

Also note that certain things affect the gestation period length, such:

  • Breed
  • Sex of calf (bull calves tend to take longer)
  • Number of calves
  • Diet

Now That You Have a Due Date- Now What?

So now that you have figured out your cow’s due date, now what do you do?

First, write down the due date. If you have a homestead binder or herd management binder, that’s the perfect place to record this information. That way you won’t forget it and end up waiting and wondering when the calf will arrive and ultimately end up scrambling when they arrive unannounced.

You should also make sure your pregnant cow(s) are getting optimum nutrition.

Pay attention to her body condition and make sure she is not too fat or too thin. Make sure she has access to fresh water, hay, grass, and is fed the optimal diet.

Preparing for Calving

As your cow’s due date gets nearer, you need to be prepared.

This means gathering all of your supplies.

Checking on your cow often and watching for signs of calving.

You should also keep an eye out for certain pregnancy related illnesses such as Toxemia or Hypocalcemia.
