국문 초록 (Abstract)

國內에서 飼育되고 있는 Holstein種 成牧牛의 血液上의 標準値를 얻고저 全南地域에서 飼育되고 있는 外見上 建康하다고 認定된 經産牛 670頭를 對象으로 血液上을 調査 檢討하여 다음과 같은結論을 얻었다.
1. 平均 RBC數의 現實値는 6.06(3.20~9.74)x 10??/㎕이었으나 正常値는 6.35(5.00~8.95)x10??/㎕이었으며 年令의 增加에 따라서 漸漸 減少하는 傾向이 있었다.
2. 平均 Hb量의 現實値는 9.42(5.3~18.4)g/100ml 이었으나 正常値는 10.11(8.0~13.9)g/100ml 이었으며 年令의 增加에 따라서 漸漸 減少하는 傾向이 있었다.
3. 平均 PVC値의 現實値는 31.04(19~55)g/100ml 이었으나 正常値는 32.30(27~42)g/100ml 이었으며 年令의 增加에 따라서 漸漸 減少하는 傾向이 있었다.
4. 平均 MCV의 現實値는 51.22(29.77~86.57) fl 이었으나 50.87(41.56~62.00)fl로 現實値보다 낮았다.
5. 平均 MCH의 現實値는 15.54(8.21~28.96)pg 이었으나 正常値는 15.92(13.00~20.94)pg로 現實値보다 높았다.
6. 平均 MCHC의 現實値는 30.35(17.35~ 53.57)g/100ml이었으나 正常値는 31.30(28.00~36.97)g/100ml로 現實値보다 높았다.
7. 平均 WBC수의 現實値는 10,408(3,200~31,600)/㎕ 이었으나 正常値는 9,233(4,810~14,000)/㎕이었으며 年令의 增加에 따라서 漸漸 減少하는 傾向이 있었다.
8. WBC 감별계수의 正常値는 임파구가 66.00(50~80), 單核球가 3.35(0~9), 好中球가 26.06(10~38), 好酸球가 4.24(0~11)그리고 好鹽基球가 0.35(0~2)% 이었으며 現實値와 비슷하였다.
9. 淋巴球는 年令의 增加에 따라서 漸漸 減少하고 있었으나 單核球와 好中球는 年令의 增加에 따라서 漸漸 減少하고 있었다.
10. 平均 血小板數의 現實値는 243,645(93,000∼57,000)/㎕이었고 正常値는 248,453(116,000~445,000)/㎕으로 現實値와 거의 비슷하였으며 年令別 差異는 認定할 수 없었다.

In order to get the normal blood values, blood samples were taken from 670 healthy Holstein cows in Chonnam province. The result obtained in the present experiment are summarized as below.
1. Determined average red blood cell count was 6.06(3.20∼9.74)x 10??/㎕, whereas average red blood cell count obtained from the results in the normal range(normal) was 6.35(5.00∼8.95)x10??/㎕. The red blood cell count tended to decrease with age.
2. Determined average hemoglobin content was 9.42(5.3∼18.4)g/100ml. whereas normal hemoglobin content was 10.11(8.0∼13.9)g/100ml. The hemoglobin content tended to decrease with age.
3. Determined average packed cell volume(PCV) was 31.04(19∼55)g/100ml, while normal PCV was 32.30(27∼42)g/100ml. The PCV appeared to decrease with age.
4. Determined mean corpuscular volume(MCV) was 51.22(29.77~86.57) fl. Normal MCV was 50.87(41.56∼62.00)fl, which was lower than the determined MCV.
5. Determined mean corpuscular hemoglobin(MCH) was 15.54(8.21∼28.96)pg. Normal MCH was 15.92(13.00∼20.94)pg, which was higher than the determined MCH.
6. Determined mean corpuscular hemoglobin concentration(MCHC)was 30.35(17.35∼ 53.57)g/100ml. Normal MCHC was 31.30(28.00∼36.97)g/100ml, which was higher than the determined MCHC.
7. Determined average white blood cell(WBC) count was 10,408(3,200∼31,600)/㎕, whereas normal WBC count was 9,233(4,810∼14,000)/㎕. The WBC count appeared to decrease with age.
8. In the normal WBC differential count, the values were lymphocyte 66.00(50∼80)%, monocyte 3.35(0∼9)%, neutrophil 26.06(10∼38)%, eosinophil 4.24(0∼11)% and basophil 0.35(0∼2)%, respectively. No differences were found between the determined and normal values.
9. Lymphocyte count tended to decrease with age, while the reverse was the case with monocyte and neutrophil count.
10. Determined average platelet count was 243,645(93,000∼570,000)/㎕, whereas normal platelet count was 248,453(116,000∼445,000)/㎕. The platelet count did not change with age.
