Comparison of some serum biochemical parameters between lactating and non-lactating dairy cows in selected dairy farms of Chittagong district of Bangladesh

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.

Abstract. A follow-up, comparative study was designed for the description of differences between two divergent laying hen strains, a Leghorn type and a medium heavy body (MHB) genotype (Hy-Line Brown), in chemical body composition and serum biochemical parameters determined at 3, 4, 6, 8, 10, 12, 14, 18, 20, 25, 30, 52 and 72 weeks of age; each time 5 birds of both genotypes were analysed and exterminated for body composition analysis. Resulting from the genotype-associated differences, the bodyweight of the populations differed from week 20 on. In the chemical body composition dry matter content was similar, while crude protein was higher on weeks 3, 8, 10, and after 18 weeks in the Leghorns. Crude fat content was higher in the brown birds (weeks 8, 10, 25, 30). Total serum protein and albumin showed slightly increasing trends, while serum creatinine concentration showed a downward trend in both genotypes, the MHB birds having higher values. Triglyceride concentration showed a drastic step-up at 17 weeks by changing to the pre-layer diet, coupled with marked between-genotype differences. This quick increase was matched by concentration drops in total and HDL cholesterol, the serum HDL cholesterol of Leghorns being always lower. Sodium concentration showed an increasing tendency with body DM content (R2=0.914, P<0.001, n=115). The Leghorns tended to show minimally higher Ca concentrations. The γ-GT activity was always higher in MHB birds, indicating a less effective hepatic adaptation to the peak production. Applying discriminant analysis to classify the genotypes, 94.4% of the original grouped cases was correctly classified, using all variables.

The present study was carried out to investigate the physiological comparison of some serum biochemistry between lactating and non-lactating dairy cows in selected dairy farms of Dhaka district of Bangladesh. The aim of the current study was to evaluate the serum parameters like glucose, total protein, total cholesterol, calcium and phosphorus concentration and these parameters were measured by the serum analyzer for lactating (n=50) and non-lactating (n=50) dairy cattle which were selected from various selected dairy farms of Dhaka district. The results (mean ± standard deviation) of the study showed that among the serum biochemical parameters total protein (84.2±1.18 gm/l) and total cholesterol (156.36± 3.41 mg/dl) level in non-lactating cows were higher than the value of lactating cows as (80.14±2.31 gm/l) and (138.21± 1.21 mg/dl). On the other hand, serum glucose, calcium and phosphorus level in lactating cows (68.12± 2.34 mg/dl), (12.06±3.21 mg/dl) and (8.30±0.20 mg/dl) respectively were found higher than the non-lactating cows (60.32 ±1.42 mg/dl), (10.48±5.60 mg/dl) and (6.31 ±0.12 mg/dl). In case of parity-wise biochemical parameters were insignificant variation was found. It may be concluded that biochemical parameters variation present between lactating cow and non-lactating cow is important for interpretation of laboratory data and also for physiological diagnosis.
