We used the string method for measuring (length X girth X girth / 400) to estimate weight on our butcher hog and it was almost exact, that hog was a mongrel mix we picked up for butcher. I have read that it does not work for Large Blacks. Has anyone done that before a slaughter and compared the difference. I am going to measure one of our gilts in March when I take her to the butcher but was wondering if anyone else has compared measuring this way against butcher weight.
We use the string method on our hogs. The string is a better estimate as our hogs are longer than the hog tape allows! Right now this works for us, however if you are strictly pork production, I think it would be important to have a livestock scale. Melissa
I know (or think) the girth is measured immediately behind the front shoulders (I know…front…shoulder…redundant) but don’t know the starting/ending point for length. I also need tpo know the mathematical equation to use.
The way it was explained to me:
Wrap the string around the torso/rib cage, keeping it as vertical and straight as you can, directly behind the front shoulders. Length should be from the base of the skull, between the ears down along the spine to the base of the tail.
Keep all measurements in inches to get the answer in pounds.
