Heat Detection in Cattle (Video)

I have put together a short video demonstrating the 3 stages of estrus in cattle.  Many may think this is very basic information, but I remember years ago when we synchronized our first set of cow, and I didn't have a clue what exactly I was looking for when I was sent out to "heat check."

Ideally, a heifer or cow should be inseminated 10 hrs after standing heat ends.  Sounds simple??? Not really.  Cows do not tell us when they start, they don't tell us when they end, and they definitely don't wait for daylight hours to show us.  I typically like to inseminate 12-24 hrs after I observe an animal in "heat."

Here's my rule of thumb:
Heat observed between sunrise and 9am - breed between 6pm-8pm
Heat observed after 9am - breed between 6am-8am of next day

Feel free to email or call me if you have any questions.

Thanks for watching!
