As anyone knows, if you are a breeder, baby watch is frustrating, time consuming, and inconvenient, yet most rewarding. There are most always one or two ladies that were pregnant --- confirmed by ultra sound, blood tested or gave a positive spit with repeated exposure to males. They are way past the due date --- they don't look pregnant, though this is not a good rule of thumb, or they go down when they see a male. OPEN! O.K. So where did the baby go? She either miscarried or reabsorbed. Miscarried? Never found a baby. Reabsorbed? How do you do that? This was always hard to imagine, how the body can reabsorb a baby. Well, I understand just a bit better now. We found two sets of twins that had miscarried. Since we hand breed, we have a pretty good idea as to when they conceived.  One set was 45 days old, found in the barn as a glob of goo. On further inspection we ascertained it was a fetus. Took it to the house and put a clear plastic wrap on a white dish and started ever so gently spreading it out and withdrawing the mucus type fluid that was encasing the baby inside the soft sack. Wow - we have two in here! The one fetus appeared to be in a proper state of development, while the other fetus was very fluid and underdeveloped. It seemed to be in a process of disappearing --- truly reabsorbing.
 About three months later we came upon a lady birthing. She was not due. We could see right away that there were two fetuses. We did the same thing with these twins. Cleaned them up and took pictures of them as well. This set was 7 months along, so being they were larger we could get a better perspective on the second baby's re-absorption. The bones of the reabsorbing fetus felt like cartilage and the flesh, that should be solid to the touch, was a sack of liquid. The rib cage, spine and pelvis were fluid. Only the legs and head were like cartilage. This whole process gave me a new prospective on how a re-absorption could possibly occur.
Llamas are supposed to have only one cria, not multiple births. Nature seems to know this. Not to say that llamas don't have twins, they can and have, but it is far easier on the female's milk production to only deal with one cria at a time. I found this most interesting and thought you might, as well. Mother Nature is amazing. Web Site:www.pearsonpond.com Email Tracy:pprllama@direcway.com Copyright © 2005 by Tracy Pearson
The following are useful terms from Dr. David Anderson: - "Miscarriage" is not a veterinary term, so we do not use it.
- A resorption occurs up to the time of fetal development (e.g. before 30 to 40 days)
- Embryonic loss / early embryonic death refers to loss of pregnancy before stage of fetal development
- Fetal wastage or fetal loss occurs after period of fetal development begins (e.g. > 30 to 40 days)
- Abortion is expulsion of any FETUS before it is able to sustain life outside of the womb. So this goes up to very close to time of birth.
- Premature birth is prior to normal gestational length, but may or may not be able to sustain extrauterine life.
