[QUOTE="Jessica06, post: 1070638, member: 5612"] Just watched the video. We were taught a different way, and I wouldn't even consider doing it the way they show in the video! Too many things to keep track of. :) First of all, if you can have someone hold the tail up for you, your life will be much, MUCH easier, and it will go a LOT faster. That being said, I use orange top blood tubes that I have (hopefully) prenumbered in order 1-.... As each cow goes in the chute, I write their tag # on the opposite side of the label. After my helper/husband holds the tail up and straight (or as much as possible!) I take a rag and do a couple of swipes to clean off the area I'll be drawing from. I take the tail with my left hand (I'm right handed) and use my thumb to find the depression in the tail bones where the vein is. I try to use the part of the tail towards the end of the web that's on either side of the tail, not closer to the base like they do in the video. That's deep! I use an 18 ga needle on a 3 cc syringe, which I stick in about 1/4" - 1/2" or so..however deep I think the vein is (some cows have really skinny tails, others not-so-much), and pull back on the plunger. If I hit it (yay!), I pull at least 2 cc's, 3 if possible. If not, I'll pick a different spot about an inch up or down the tail. Some are just really hard to find. Once, I finally had to give up and get it out of her ear. When you have enough, take it out and then stick your needle through the top of the tube. The vacuum pulls the blood in. It's really not rocket science, and once you get the hang of it after a few head, it's a piece of cake. Whichever method you end up using! [/QUOTE]
