Tail Bleeding
Raise tail up and locate the 2nd and 3rd vertebrae from the trunk. Note circles.
Right down the mid line about a half inch inside the skin is the main tail blood vein nearly a quarter inch thick.
Feel the soft muscle dead center between the vertebrae. Right in the middle between the vertebrae is the spot. Go right between the bones.
Be humane, use a very small needle.
Slight pull on the syringe and you have it. If not, pull out slightly and pull again. You are there.
For preg checks only 3 cc needed. That is it, less than a minute if the cow is squeezed tight in a good chute, otherwise might take all day.
When the cow returns to the corral, the friend/cows ask, what are those little circles under your you-know-what. She says -- none of your business.
