Watching all the news where they are using these infrared thermometers to check for the coronavirus made me wonder if they can be used on cows and calves? Sure would be easier than having to catch one in the chute and use a rectal thermometer.
If they would work, where would you point it, at their forehead?

I know the high end models are very accurate, we have a few flir models at work and a few others. As far as using on a calf, I'd guess hair would change the reading drastically. Think you need to aim somewhere around the rectum or in the mouth.

I don't know how accurate it would be on cows, the way they dissipate their body heat..through the mouth and hide..seems through the rectum would get the most true reading..

Nice thought, but from my experience there is a significant difference in core temperature vs surface. The hide/hair works both ways.
Plus as mentioned, color makes a difference. I've shot a few black vs red in the summer and cant remember exact numbers but it was over 10 degrees if I remember correctly.
Over 15 years ago they were working on buluses that would sit in the rumen and transmit internal temperature. Not sure where that's at now.

I think that probe on that one is reading inside the ear canal, birdog. It's kinda like the thermometers that a lot of doctor offices have gone to, but stay in place. The ear canal would be more representative of core temperature vs the thin flap that would vary more with ambient temperature. Interesting, but would think that would be irritating and if it wouldn't cause problems acting like a foreign body. |
