Hematologic and serum biochemical reference values in chemically immobilized free-ranging sambar (Rusa unicolor)

Abstract

Hematological and serum biochemical reference values for 33 free-ranging sambar deer following immobilization with medetomidine (70–100 μgkg−1) and ketamine (1–2 mgkg−1) in Sariska Tiger Reserve in India were established and the differences across sex and age group were compared. Hematological and biochemical variables across different age-classes for red blood cell count, eosinophils, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, triglycerides, and blood glucose varied significantly though the hematological values did not vary between sexes. Blood urea nitrogen and creatinine levels were significantly influenced by sex in the present study. Interpretation of the result, however, needs to be made with caution due to the low number of sub-adult compared to adults in the present study. The study highlights the need for understanding the source of individual variation for meaningful interpretation. This paper provides the first report of baseline hematologic and serum biochemistry values for free-ranging sambar deer that can form basis for assessing the state of health and nutritional condition of the animal.
