Clinical biochemical reference ranges for female alpacas (Lama pacos).

1. Serum samples were collected from 352 healthy female alpacas and tested for 17 clinical biochemical analytes. 2. From the total population of alpacas tested, 205 were pregnant, 68 were not pregnant and 79 had an unknown pregnancy status. 3. Reference ranges for the female alpacas were determined for all the biochemical analytes, and compared to ranges reported for llamas, cattle, sheep and goats. 4. The mean values for pregnant and non-pregnant females were compared and any statistically significant differences identified. 5. The biochemical values reported here are suitable as reference ranges for pregnant and non-pregnant female alpacas.
