If you take blood samples from the caudal vein under the tail, there is a technique that you rarely hear. Lift the tail, locate the third caudal vertebra. Insert the needle in the center of the vertebra. There is a groove you can feel with your thumb. About half an inch into the flesh of an adult cow, you should encounter the vein. BUT, if you have the face of the bevel facing forward, the blood is 10 times easier to draw.

Never paid attention to bevel direction.

Never paid attention to bevel direction. Try it. It works. I learned this from Bovine Breeder. |

Is bevel up or down? My thinking is the bevel always on the forward end of the needle.
