Abstract
The aim of the present study was to know the normal haemato- biochemical profiles of black Bengal goats in Bangladesh. Blood samples were collected from Jugular vein of 20 Black Bengal goats which were divided into 5 groups (4 goats in each group) on the basis of age, sex, nutritional and feeding status. The whole blood was analyzed for hematology, plasma and serum samples for biochemical analysis. The results of the present study demonstrate the normal haemato-biochemical values of the Black Bengal goat breeds with their age specificity. Total RBC (15.15 ± 1.29 million/cumm), haemoglobin (7.04 ± 1.02 g/dl), total WBC (11.64 ± 1.12), differential leukocyte counts of neutrophils (70.89 ± 2.06%), lymphocyte (23.79 ± 1.69%), eosinophil 2.1%), basophil (2.3%), MCV (35.04 ± 0.47) and PCV (26.98 ± 1.49%). This study also reveals the normal bio-logical profile counts as total protein (69.47±2.31 g/L), Albumin (42.47 ± 2.31g/L), Globulin (27.32g/L), Phosphorus (3.46 ± 1.19), blood Urea (22.97 ± 0.58), Creatinine (0.645mg/dl), ALT (20.32U/L), ALP (91.59 U/L), GGT (37.46 U/L), IgG (18.91 ± 1.14 g/L), IgM ( 2.87 ± 0.18g/L), gA (.031 ± 0.12g/L) and IL-6 (1.69±0.15g/ml). The study found higher number of RBC (million/cumm), WBC (Thousands/cumm), and PCV% in the goats of age 3 years and above (18.02 ± 1.27, 14.72 ± 1.19, and 28 ± 3.2), respectively. Besides, Neutrophils% and total protein was found higher (76.289 ± 14.5%, 77.52 ± 8.43 g/L), respectively in the Black Bengal goats of 6 months to 1 year age. Present results stated some significant variation of parameters between goats of various ages; on the other hand, some shows no significant variation at all.

Summary
Livestock has been an important component of the mixed farming system practiced in Bangladesh. The goat provides meat, milk, and skin and contributes 38.0%, 23.0% and 28.0%, respectively (Devendra, 2007). Goats are considered as ideal animals to keep for their high ability to survive under severe conditions and their ability to produce high-quality meat and milk (Silanikove, 2010).The Black Bengal goats are dwarf goats and are known to be famous for its adaptability, fertility, fecundity, delicious meat, superior skin, extreme disease resistance and wide range of acceptability under adverse agro-climatic condition (FAO, 2008). Capacity to subsist on harsh nutritional regime and low risk of death make a viable proposition for increasing the productivity of Black Bengal goats in Bangladesh (Hassan et al, 2011). Blood is an important and reliable medium for assessing the health status of individual animal (Ramprabhu et al, 2010). Hematological and serum biochemical tests are widely used for the diagnosis of serious animal diseases which can lead to economic losses in animals like reduced fur, wool and milk production (Bani et al, 2008)
