Haematological and Serum Biochemical Analyses of Wild Male Blackrats, Rattusrattus (Linnaeus, 1758)

The present study focuses to evaluate the haematological and biochemical profile of wild black rats. In this study, the estimated values of Rattus rattus with respect to age were compared. A total of 40 black wild rats (20 each from youngs and adults) were collected. Blood samples were then collected from the caudal vein of anaesthetized rats. Haematological parameters such as haemoglobin (Hb), total erythrocyte count (TEC), total leucocyte count (TLC), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) and the serum biochemical parameters like protein, albumin, globulin, glucose and cholesterol were measured and each parameter was expressed as meanSE in both young and adult rats and compared according to the age group using t-test. In haematological findings, all parameters namely RBC, Hb, MCV (pless than0.001) and MCHC, PCV (pless than0.01) and WBC (p0.5) reveal significant difference between young and adult rats. But, no significant difference was observed in MCH. The biochemical parameters such as total protein, cholesterol, glucose (p 0.001), and globulin (p0.01) reveal significant difference where ass no significant difference was recorded in albumin between youngs and adults. The findings would be helpful to establish a baseline value and to draw conclusive remarks as to the health status of Rattus rattus.
