This will have variations based on breed, however it might not be as big of a difference as you might think. As you can see from our video, the Dorper lamb is 6 months old and around 70 pounds. I would go for the biggest you can get! 😎
We had our herd type classified last fall. Would recommend it to anyone. We learn something every time we do this. Our buck had a testicular circumference of 34.5cm as a two year old. I am pleased that you showed the buckling because we sell our breeding prospect males before 14 months of age and I was wondering about where they should be at when it comes to testicular circumference. It would be nice to have a crystal ball but we don't know how they will turn out in the future!
