Abstract

While few studies have outlined the effect of captivity on primate behaviour, haematological and biochemical changes are often understudied. Thus, this study aimed to compare clinicopathological findings of lar gibbons in different management systems, age and sex by examining haematological parameters including erythrocytes, haemoglobin, packed-cell volume (PCV), mean corpuscular volume (MCV), platelet and differential leucocyte count along with serum biochemical parameters namely sodium, potassium, chloride, calcium, phosphate, total protein (TP), albumin, globulin, urea, creatinine, aspartate aminotransferase (AST), creatine kinase (CK), alanine transaminase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), amylase, glucose, lactate dehydrogenase (LDH), bilirubin (conjugated, unconjugated, total), cholesterol and lipase. Blood samples were obtained via convenient sampling from clinically healthy lar gibbons in three locations which comprise of Malaya Gibbon Rehabilitation Project (GReP) (n=11), Zoo Taiping (n=2), and Zoo Melaka (n=3). Retrospective data from a previous blood test was obtained from Zoo Negara (n=1). Information on diet, enclosure specifications and environmental conditions were acquired. Results showed that between captive and semi-captive gibbons, the former displayed a significantly higher (p<0.05) monocyte, sodium, TP, globulin, GGT and cholesterol levels while semi-captive gibbons had significantly higher (p<0.05) potassium, chloride, albumin, urea, LDH, bilirubin (total, unconjugated), and lipase. Adults had a significantly higher (p<0.05) monocyte count in comparison to the adolescents, while higher values of ALP were recorded from the juvenile group. Within females across types of captivity, captive females recorded a significantly higher (p<0.05) TP, GGT and cholesterol while semi-captive females had significantly higher (p<0.05) levels of potassium and chloride. In conclusion, it is suggested that different management systems may have contributed to the variable values in overall serum biochemistry of lar gibbons, possibly due to different diet given. Hence, this study can be used to modify the captive lar gibbon’s management system to improve conservation and rehabilitation efforts.
