Abstract:
In this study a total of 40 whole blood and plasma samples were collected from 30 pregnant dairy cows in different stages ( first , second and third stages ) of pregnancy and 10 from empty cows as control to evaluate the profile of certain hematological parameters and biochemical parameters with main aim to protect pregnancy cows from production disease .
The survey was conducted at Khartoum State and the area selected were West Omdurman ( Alrodwan ), JabalAwlia ( Aldikhinat ) and East Nile ( Sudan University farm and Soba) .Haematological findings revealed that , there was a significant changes in the packed cell volume ( PCV) and slight changes in hemoglobin ( Hb) within and between the group of pregnancy cows compared with control group (P< 0.05 ) . PCV was low in first stage (52.6±6.6ml/dl) , and in third stage (74.0±6.4mmol/l) respectively compared with control group (76.4±4.5mmol/l) , whereas in the second stage PCV was high (86.5±1.3mmol/l) . there was slight changes in haemoglobin concentration, during the first stage there was a decreases (7.3±1.3g/dl) , whereas in the second stage (12.8±0.7g/dl), and third stage (11.9±1.0g/dl) the level was more than control group was (11.4±0.9g/dl)
The total protein was (169.0±30.3 g/l), (88.2±8.8g/l) in first stage and in third stage respectively and both were higher as compared with controlled (67.8±3.6g/l) , the second stage (57.4±1.9g/l) it was low . The albumin value showed increases during first stage and third stage (69.9±12.9g/l) , (44.0±8.0g/l) respectively , whereas the second stage (26.6±1.8g/l) was lower than control group (28.5±3.9g/l) . The globulin in second stage of pregnancy was low (30.7±2.7g/l), while in first stage (99.8±17.9g/l)and third stage(42.4±7.0 g/l) it was high as compared with control group (39.3±4.1g/l) . Plasma glucose and calcium there were significant change within the group .The glucose level was decreased in the first and second stage of pregnancy (4.1±0.3mmol/l , 4.8±0.2mmol/l) respectively , whereas during the third stage (4.9±0.7mmol/l) these was increases as compared with control group (4.3±0.4mmol/l) . The value of calcium was (2.4±0.6mmol/l) in the first stage and (1.6±0.3mmol/l) in second stage , these values were both low as compared with (3.2±1.2mmol/l) in the control group , the third stage (3.8±0.9mmol/l)was increases as compared with control. The good management of pregnant cows before and after calving with treatment are important in controlling the production disease .
