Twenty lesser chevrotains (Tragulus sp.), 10 males and 10 females, were anesthetized with a combination of butorphanol–midazolam–medetomidine (BMidM), to assess the efficacy of this protocol for short procedures in this genus. The animals received BMidM (0.32, 0.06, 0.15 mg/kg, respectively) intramuscularly via hand injection. Physiological variables were recorded once the animals reached a working depth of anesthesia that lasted 30 min (range 12–60 min). At the end of the procedure, medetomidine and butorphanol were antagonized with atipamezole (0.75 mg/kg) and naltrexone (0.3 mg/kg) intramuscularly, respectively. Induction and recovery were 9.4 ± 4.0 min and 10.2 ± 4.1 min, respectively. Supplementation with isoflurane via face mask was required in five animals to reach light anesthesia. Times to reach the various stages of anesthesia were compared between sexes. There was no difference between males and females reaching the different stages of anesthesia, except for the time required to reach the ambulatory stage, in which females took a significantly longer time (11.8 min vs 7.8 min for the males) to stand after the injection of the antagonists (P = 0.02). Heart rate, respiratory rate, rectal temperature, and peripheral hemoglobin oxygen saturation were similar between sexes and stable throughout the procedure. At the dosage tested BMidM was a reliable and safe protocol for short, minimally invasive procedures in lesser chevrotains with a fast induction and smooth recovery without complications.

Protein electrophoresis (PEP) is an important tool in mammals to characterize specific dysproteinemias and detect acute and chronic inflammatory responses. In reptiles, PEP is the gold standard method for globulin fraction determination and albumin measurement. In this study, preliminary reference intervals were established for serum PEP in 22 clinically healthy adult Roti Island snake-necked turtles (Chelodina mccordi), a critically endangered species, kept in captivity and sampled over two monsoon seasons. The species has a prominent prealbumin fraction and β-globulins were the dominant globulin fraction. Significant differences between females and males were found in prealbumin (P < 0.01), albumin (P = 0.02), α1-globulin (P = 0.05) and γ-globulin (P = 0.01). Gravid females had significantly lower total protein (P < 0.01), prealbumin (P < 0.01), albumin (P < 0.01) and albumin:globulin ratio (P = 0.01). These preliminary reference intervals should aid in clinical investigation in this species as well as further research studies seeking to understand the application of PEP in reptilian species.

The Burmese roofed turtle (Batagur trivittata), endemic to Myanmar, is a critically endangered species. Little is known about their physiology and health. Therefore, establishing physiologic reference intervals is essential for the implementation of conservation plans. This study establishes hematology and biochemistry reference intervals of a group of 23 captive Burmese roofed turtles. The animals were sampled during a 4 month period, outside the breeding season. Most blood values did not differ significantly based on animal sex. However, in females, lymphocyte count and concentrations of glucose and calcium were relatively higher, and potassium was lower compared to that of males. Better understanding of blood analytes will help strengthen ex situ management and healthcare protocols as well as improve ongoing conservation efforts for this important species.
