As a mentioned before: There are a lot of immunoproblems in alpacas. You can categorise them in three groups:
- IDS / Immunodeficiency syndrome
- FPT / Failure of Passive Transfer (see article IgG)
- FTT / Failure to Thrive
The last; FTT was new for me. But now I have such an animal in my own herd.
The symptoms. The cria is growing normally til the moment of weaning. After that period the cria will loose weight. Most owners think it is because of the weaning. IgG-levels are mostly in a normal range (above 800 mg/dl). Futher studies on bloodlevels give a very low rate of iron and an anemic animal (very low RBC / red blood cel count). When the IgG level is low the prognosis is almost infaust - or at least very bad...
Most of them (but not all) will have very low thyroxine levels in their blood.
It is often first noticed at an age of 6 months. The alpaca is staying behind in growth. It is recommended that a treatment is started immidiatly after diagnosed.
Ironinjections / every 7 - 10 days.
T4 - supplement (orally) hormons
Hyperimmuneplasma should be administred
Multivitamins and selenium in feeding
Prognose 30 - 40% of the animals will die. It seems to be NON - hereditary! Females who will recover have normal crias.
We can test your animals within several minutes for their IgG Hematocriet and T4 levels. Let us know when you expect such a problem... You can also ask your vet to contact us.
Many greetings and a nice day to you,
