Back when I posted about my digital scales(the VS 660 that I love!), someone mentioned comparing the weights from the digital scales with the weigh tape.
I weighed the dairy doelings again today and then I used the dairy goat weight tape on them. I cannot compare the meat goat weights and tape as I no longer breed Boers.
Here are the 2010 dairy doeling weights by scales and by weight tape:
Legacy-#87 by scale-#93 by weight tape.
Honey-#95 by scale-#101 by weight tape.
Image-#93 by scale-#101 by weight tape.
Spritzer-#74 by scale-#84 by weight tape.
Darla-#100 by scale-#110 by weight tape.
Zambia-#97 by scale-#101 by weight tape.
Lady-#104 by scale-#110 by weight tape.
Ruby-#95 by scale-#101 by weight tape.
So, there is a significant difference. And at least with my babies, the weight tape always overestimated. I'm sure everybody handles the tape slightly different, but I was as careful as I could be.
I did find out that Zambias breast bone is a very touchy spt. Each time I tried to run the weight tape under her, she collapsed onto her chest and lay on it.........

Hopes this helps.
