Abstract Southern pudu (Pudu puda) is one of the smallest deer in the world, categorized as vulnerable by the IUCN. Establishment of reference values for hematologic and biochemical guidelines is fundamental for monitoring health and physiological status of animals. The aim of this study was to describe ranges for hematological and plasma biochemical guidelines in pudu. Blood samples were collected from 29 anesthetized pudus (21 female and 8 males; 5 juveniles and 24 adults) from a semi-captive population. Hematologic parameters, plasma concentrations of energy, protein and mineral guidelines, as well activity of enzymes markers of hepatic and muscular damage were determined. Mean, median, and reference interval hematologic and biochemistry guidelines were presented. No significant differences between genders for any parameter were observed, except plasma calcium concentrations. The plasma concentrations of total protein, globulin, triacylglyceride, and chlorine were higher in adult than young pudus. Values obtained in this study will be employed to build a database for establishing reference limits for this species. Keywords Hematology . Clinical biochemistry . Pudu . Captive . Pudu puda

The southern pudu (Pudu puda) is one of the smallest deer in the world with an adult size of about 40 cm in height and 9 kg in weight (Silva-Rodríguez et al. 2011). The pudu inhabits the South American temperate rainforest and is categorized as vulnerable. The distribution and density of pudus populations have declined during the last decades. The main causes for the decline are forest loss, predation by domestic dogs, and poaching (Silva-Rodríguez et al. 2010). The current scenario has made necessary the development of ex situ and in situ conservation initiatives. Therefore, captures, translocations, rehabilitations of injured pudus, and releases from both breeding centers and confiscated animals are an increasingly common practice (Silva-Rodríguez et al. 2011). In order to not affect the health of wild populations and improve the management of captive animals, it becomes necessary to gather information that allows the establishment of physiological responses in this species (SilvaRodríguez et al. 2011). The blood participates directly or indirectly in almost all
