Analysis of Hematologic Characteristics of Korean Native Stripped Cattle Chikso according to the Ages

Investigations for hematologic values and the differential count of WBC for Korean indigenous cattle (KIC) and Stripped Cattle (SC) are rarely performed. Therefore, when the index of complete blood counts (CBC) analysis of KIC and SC were requested, it had many difficulties to make the results for blood condition since the standard hematologic values of KIC and SC are lacking. The objective of this study was to investigated the hematologic values and the differential count of WBC for blood of total 19 striped cattle (SC) and 187 KIC as a control by estimation analysis of hematologic characteristics. As a result, the mean values of RBC and platelet of KIC were significantly decreased by age (p<0.05). The mean values of RBC, HCT, MCV and MCHC between KIC and SC of the same age (2~3 years) showed the statistical significance (p<0.05). Also, in the WBC of KIC, the mean values were decreased according to the age from 13.8 × 103/μl under 1 year to 9.5 × 103/μl over 5 years. In the differential count of WBC of KIC, it showed generally the rates of 46.2% lymphocyte and 36% segmented neutrophil. Additionally, in comparative analysis between pregnant and non-pregnant group of KIC, the mean values of Hg and HCT in pregnant group were significantly decreased(p<0.05). In conclusion, data obtained from this study may be valuable as a standard for interpretation of the results in hematologic analysis of KIC. Result of this study will be used for establishing reference range for hematologic analysis in SC.
