The Hematological Parameters and Serum Protein Values in Tuberculin Reactor and Non-reactor Dairy Cattle

Abstract

The study aimed to evaluate some blood parameters and serum proteins in dairy cattle farm in Baghdad Governorate Iraq. The study was conducted on 100 dairy cattle both sexes (13 males and 87 females) aged 1-6 years, 1-2, >2-3 and >3-6 age groups. A comparative intradermal tuberculin test was carried out on these animals. The results showed that the range and mean ± standard error (SE) of hematological and serum protein values were as follows; Hb 3-15 g/dl and 9.37 ± 0.27 g/dl, PCV 12-44.5% and 30.7 ± 0.96%, RBCs 3-10 × 106/µl and 6.37 + 0.20 × 106/µl, total WBCs 4000 -20000/µl, 9606± 431/µl, ESR 2-12 mm/1 hr and 4.44 ± 0.21 mm/1 hr, Total Serum Protein (TSP) 2.1-8 g/dl and 6.00 ± 0.14 g/dl, Serum Albumin 0.9-3.5 g/dl and 2.42 ± 0.06 g/dl and Serum Globulin was 0.8- 4.9 g/dl and 3.58 ± 0.08 g/dl. The males showed a significant decrease (P<0.05) in globulin compared to that of females, and the >2-3 years age group showed a significant increase in globulin compared to that of the >3 years age group. On the other hand 28 out of hundred (28%) cattle were tuberculin reactor and the values in tuberculin reactor and non- reactor were as follows; Hb 7.82 ± 0.64 g/dl and 9.98 ± 0.24 g/dl, PCV 24.57± 2.1% and 33.08 ± 0.91%, RBCs 5.34 ± 0.48 X 106/µl and 6.77 ± 0.19 × 106 µl, WBCs 11786 ± 1033/µl and 8758 ± 406 /µl, ESR 4.41 ± 0.35 mm/1hr and 4.45 + 0.26 mm/1hr, TSP 5.55 ± 0.34 g/dl and 6.18 ± 0.13 g/dl, Serum Albumin 2.51 ± 0.15 g/dl and 2.38 ± 0.06 g/dl and Serum Globulin 3.05 ± 0.20 g/dl and 3.79 ± 0.07 g/dl respectively. The Hb, PCV, RBCs, WBCs, TSP and serum globulin showed a significant differences (P<0.05) between tuberculin reactor and non-reactor. In conclusion, the current study recorded changes in some hematological parameters and serum proteins in relation to sex, tuberculin reaction and different age groups in dairy cattle.
