- Measure the circumference of the animal, as shown in distance C in the illustration. Make sure to measure girth in relation to the location of the animal’s heart. On a sheep, ensure an accurate measurement by compressing the sheep’s wool so that the circumference reflects that of the body and does not include that of the body plus the wool.
- Measure the length of the animal’s body, as shown in distance A-B in the illustration.
- Using the measurements from steps 1 and 2, calculate body weight using the formula HEART GIRTH x HEART GIRTH x BODY LENGTH / 300 = ANIMAL WEIGHT IN POUNDS. For example, if a sheep has a heart girth equal to 35 inches and a body length equal to 30 inches, the calculation would be (35 x 35 x 30) / 300 = 122 lbs.
It was that time of the year, Time to do a full sheep checkup, they had a full body check, feet trimmed, they were measured and weights figured out, wormed and for the main flock given their vaccine boosters.
Mom was in charge of the book this year, she took the measurements given, figured out the math with the cheat sheet that hubby made for her(she was having trouble moving from kilograms to pounds) and made up the wormer shot and the vaccine needle for me.
Thanks for the help mom, (even if she did say she was freezing)
Here is just a bit of the information that went into the farm book for doing them. yes, I now that bigger farmers would be writing in numbers but my flock is small enough that I know each one by name, each ewe has her own color, marking etc that I can tell them apart. The hair sheep are a much smaller breed then the wool sheep are, yet even between them, I have a bigger line and a smaller line.
