Abstract

Objective: The study was focused to investigate the
occurrence of a fatal capture myopathy (CM) after chemical immobilization
during translocation in different places and to evaluate serum enzymes of
stressed deer and pathologic alteration of vital organs of dead animals due to
CM.

Materials and Methods: The
experimental data was collected from Bangladesh National Zoo, Dhaka and the experiment
was conducted at the Department of Surgery and Obstetrics, Bangladesh
Agricultural University, Mymensingh. Immediate
after capture the animals were allowed to normalize body temperature by pouring
sufficient water over the body. Peripheral blood was aspirated from jugular
vein for serum biochemical analysis. Once the animals died, vital organs were
collected and processed for histology. 

Results: Data from 2013 to
2018 revealed 178 animals captured through darting and among them 40 animals
died due to post-capture myopathy reflecting death rate of 22.47%. We have
closely studied on 16 animals captured on different occasions. Serum enzyme
analysis were exhibited increased levels of ALT, AST, Bilirubin, Creatinine,
BUN, LDH, CK, Troponin, Cholesterol, Triglyceride, HDL and LDL and were highly
indicative of stress-linked muscle and organ damage. The macroscopic lesions
consisted of muscular and cardiac degeneration, edema, hemorrhage and
congestion in lung, adrenal gland and in kidney. Microscopically there were
loss of striation and fragmentation of skeletal muscle, formation of
contraction band necrosis in myocardial fiber, degenerative changes in renal tubule
and formation of central intraluminal eosinophilic casts.

Conclusion: The pathological findings were indicative of capture myopathy in spotted
deer. This report underlines that mortality from capture is a risk that must be
considered during restocking programs.
