Swine barn, Lafayette County Fair.
Because of my background as a certified swine ultrasound technician, the fair superintendent asked me to line-up a technician. Ultrasound is used to evaluate a hog’s carcass. Below is a picture of the technician with the probe on a hog’s back. The information is entered into a computer and a formula is used to rank the hogs on percent lean.
The measurements taken are backfat and loin muscle area. These two statistics, along with the weight of the hog, are used in the percent lean formula. Look at the screen in the picture below and see if you can see the layer of backfat above the roundish loin muscle area, (pork chop). Also visible is a rib in the lower right-hand corner.
Even though I used to be an ultrasound technician, I miss the old days when we actually measured the carcass. We would show our hog at the fair on Friday. Sell it at the auction on Saturday. Load it onto the trailer on Sunday. And see it’s carcass hanging on the rail on Wednesday.
One summer my sister went to band camp and as introductions were made, each camper told what they had been doing this summer. When it was my sister’s turn, she said, “I got a blue ribbon at the carcass show.”
