Sheep Weights – Figuring them out with measurements

sheep-diagram

  1. 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.
  2. Measure the length of the animal’s body, as shown in distance A-B in the illustration.
  3. 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.

    Ah thank you, we’re currently learning this in our classes. Always nice to see practical applications at work!

    • While I can certainly see why it would need to be taught, and would be used on the rare time a vet is needed for help with the sheep flock, I have to admit that to me at least and most of the folks I know that have sheep or goats, we do all the routine care and I am grateful that we can do so 🙂

      I love that the ag folks for Ontario, hold seminars on sheep or goat care each year.. I have been able to attend classes on all kinds of things like this, but without a doubt the lamb birthing and care was one of the best of them all.

    What vaccines are you giving and when do shear wool?

    • Hi Lori, I give Tasvaz 8, it covers Tetanus, Black leg and a got of other ones that are local to my own area, as the farm I am at has been around for a 100 years and that the land is limited and the land has had large numbers of sheep and goats over the years, I did not have much choice, I was having real issues until I started with the vaccines and now I have no issues in the main flock at all since health wise.

      Having said that I have a girlfriend less then an hour away and she gives a different route, it really needs to be something you talk to your vet about and find out what your land has, and or what your flock came in with.. you can certainly manage certain things with good feed and hay but somethings are out of our control and we need to give a helping hand to them.

      As for wool, that is a fall thing and will be happening very shortly, If I did not have the barns, I might have done it in late sept but because I have the barn to put them in for a couple days to get use it, plus I will not take the two wool adults to a short coat, I will leave them some.. the lambs howeer, one will be sheared right down and put in a coat and the other two are being left as I want to make use them for sheepskins and I need the wool left on for butcher and then send them out.. I have no issues doing hides but I am not going to train on those two amazing wool hides 🙂

      • Lori says:

        Yes, I understand about the shots. We have a real problem with worms in our wet cool climate and are always dosing them up. We just castrated and medicated them all then we will be butchering in 30 days and
        I am really interested in how you prepare the sheepskins. Have you posted on that?

      • Hi Lori, I have done some posts on the rabbit hides, at least one on a calf hide and I did a few on the big steer hide I did but not sure I have done a lot on the sheep.. guess that means I should do one on it this fall.. so keep a eye out for it 🙂

    Your Mom looks ready for anything the weather could throw at her. What a trooper!
    LOL, just a glance at the names on that sheet made me hungry; )
