When an alpaca baby is born, we draw blood for a couple of reasons. First is to send a blood sample in with the alpacas registration. The second reason is to test the immunoglobulin G or IgG. The best way to describe IgG is that this tests the level of antibodies in the blood to protect the cria from disease.
You want to see an IgG test of at least 800 or above. For instance, most of our alpacas this year have been in the 3500 level. A level between 500-800 is borderline, but not terrible. Robinson Crusoe’s IgG was around 300. TOO LOW!! This is a problem We have been noticing that he has just been laying around, not gaining weight, not nursing as often as needed. All signs that he probably had a low IgG. His low IgG probably comes from he was born a month early and Liberty Blaze hadn’t started producing colostrum yet in her milk. The colostrum is how the mom transfers the good antibodies to the cria.
To take care of a low IgG you need to give a plasma transfusion to add the antibodies that the alpaca needs. We had our Vet, Dr. Pete, come over to do the transfusion. The best way to do the transfusion of plasma is in to the abdomen. There is about a 2% loss of the antibodies this way over adding the plasma directly to the blood, but since it is llama plasma, this causes less stress to the system than doing it in to the blood. It’s worth the 2% loss to not have other problems.
Mom and baby did well while the Dr. did his work.
Here is Dr. Pete, Megan his assistant and Julia getting Robinson Crusoe ready. They have shaved his belly, and holding him down and then cleaned him really well.


Here you can see Dr. Pete with the plasma:

Here is Georgia helping out afterward. He was pretty worn out afterward.

Today, Robinson Crusoe was running around the pasture, nursing and doing great. Dr. Pete came back and drew some blood to see how the changes have done. One test came back borderline. That is an improvement. So far he is doing great. We’ll keep watching him and make sure he is doing well.
