Abstract
Physiological status-related changes in serum biochemical values are known to occur in many species. The aim of the current study was to evaluate total serum protein, albumin, glucose, calcium and phosphorus concentration and these parameters were measured by the serum analyzer for lactating (n=50) and non-lactating (n=50) dairy cattle in selected dairy farms of Chittagong district. The results (mean ± standard deviation) of the study showed that among serum biochemical parameters total protein (82.3 ± 2.15 gm/l), albumin (27.45 ± 5.06 gm/l), calcium (12.97±6.67 mg/dl) and phosphorus (7.26 ± 0.41 mg/dl) level in non-lactating cows were higher than the value of lactating cows as (81.28 ± 2.41 gm/l), (14.09 ± 2.05 gm/l), (10.05 ± 2.51 mg/dl) and (6.52 ± 0.30 mg/dl) respectively. Only glucose level in lactating cows (63.01 ± 6.67 mg/dl) was found higher than the non lactating cows (58.47 ± 3.84 mg/dl). In case of parity-wise parameters insignificant variation was noticed. It may be concluded that biochemical variation present between lactating cow and non lactating cow is important for interpretation of laboratory data and also for physiological diagnosis.Asian J.

Highlights
Blood is the fluid connective tissue peruses an immediate indication of an animal’s nutritional status at that point in time
Total protein level were found elevated than the reference value and the insignificant variation were shown among the different parity where lowest value was found in the third parity followed by first and second parity
In the case of third parity total protein, glucose, calcium and phosphorus level were found higher in lactating cows in comparison to the non lactating cows
Summary
Blood is the fluid connective tissue peruses an immediate indication of an animal’s nutritional status at that point in time. Nutritional concentrations in blood represent an integrated index of the adequate supply of nutrient in relation to nutrient utilization of dairy cows. Metabolite levels in blood serum indicate the extent of body metabolism, such as energy, proteins and minerals (Ndlovuet al., 2007). In like manner these parameters are influenced by both intrinsic and extrinsic factors like breed, age, sex, lactation, pregnancy, health and nutrition status of the cows (Aengwanich, 2002; Al-Shami, 2007; Mohammed et al, 2007). Blood tests from farm animals are routinely used to extract pertinent information relative to herd nutrition and help to diagnose metabolic disease problems in dairy cows (Van Saun and Wustenberg, 1997). In advanced animal husbandry practice the importance of
