I have pulled THOUSANDS of tail blood samples! I used to work on the research study where the research company was trying to get, I think, Cystorelin approved (it was a cystic ovary study, dairy cattle in CA were prone to cysts). My job working for the research company was to pull blood samples on thousands of dairy cattle. I was told what dairy, and what time the string would be caught in the feeding stanchions (in CA) and my job was to show up, pull a blood sample on the entire string, and label the tubes. Needless to say, I have pulled more than I care to ever count. We NEVER used a needle and syringe, that would have been cost prohibitive! Our vacutainer tubes and needles never got dirty, but our needles had a rubber end on them, like this.

The rubber on the end prevented the blood from dripping out, until you pushed the tube up on the needle. No blood, no mess. We could not afford cross contamination when collecting the samples. It was really quite simple; lift the tail, poke with the needle, push the tube on the needle, wait a few seconds for it to fill half full, then pull out and hand off the tube to the person to label while I move to the next cow and load the next vacutainer.

We send ours to SEK Gentics here in Kansas. My husband has a guy from his work that goes down that way couple times a month, so he just took the samples down for us on testing day. pulled blood sunday night, through in the fridge till Tuesday morning. Got the results Wednesday or maybe Thursday. $2.50 per test.

We are going to try these just for convenience. So for those that do it how long do you wait after exposure to test? I was thinking give them enough time to have had 2 heats since the bull was put in plus the 28 days they say they have to be bred to show a positive. Am I thinking wrong? If so it would not be the first time.

According to the company 28 days on heifers (we have pulled blood on day 29) and 28 days on cows plus 70 days post calving. So far they are 100% accurate for us on pregnancies.

We sent the test out on Monday to the Florida lab and had results Wednesday afternoon of the same week.

I guess I am asking how long after exposure? I was thinking give them 2 heats cycles plus the 28 days so at least 70 days since turning in with the bull.

Pulled our samples Saturday, out in the mail Monday and got results today. Overall fairly quick I thought, did out our convenience. Will probably do again, pulling the blood was easy on some and hard on others. A few of them probably felt like pin cushions.
