The study was conducted on forty healthy randomly selected birds which were divided in to four groups, each group having five males and five females of native, DR, DRN and DND. Forty blood samples were collected from these birds at their growing stage and forty blood samples were collected at their adult stage. The haematological parameters namely, haemoglobin, packed cell volume, total erythrocyte count, total leucocyte count, differential leucocyte count, mean corpuscular haemoglobin, mean corpuscular volume and mean corpuscular haemoglobin concentration were estimated. Blood biochemical parameters viz. glucose, lipid profile (triglycerides, cholesterol, HDL and LDL), protein profile (total protein, albumin, globulin and A:G ratio), renal profile (urea, creatinine and uric acid) along with plasma minerals (calcium and phosphorus) were estimated from the collected blood samples using standard analytical techniques. It was found that biochemical parameters viz. total cholesterol, HDL, LDL, triglycerides, creatinine, urea were significantly (p<0.05) different among all the breeds/crosses, between age groups and between males and females of the same breeds/crosses. Haematological parameters viz. haemoglobin, packed cell volume, total erythrocyte count, total leucocyte count, differential leucocyte count were significantly (p<0.05) different among different breeds and age groups which can be due to different genotype and changes with the age.ennullThesis
