        國內에서 飼育되고 있는 Holstein種成牝牛의 血液化學値를 얻고자 全南地域에서 飼育되고 있는 外觀上 健康하다고 認定된 經産牛 385頭를 對象으로 血液化學値를 調査檢討하여 다음과 같은 結論을 얻었다. 1. 平均血淸TP量은 7.35(5.10∼10.20)g/100㎖이었으며 年令의 增加에 따라서 漸漸 증가하는 傾向이 있었다. 2. 平均血淸Alb量은 3.51(2.50∼4.40)g/100㎖이었으며 年令別 差異는 認定할수 없었다. 3. 平均血淸Glb量은 3.84(1.40∼7.20)g/100㎖이었으며 年令의 增加에 따라서 漸漸 증가하는 傾向이 있었다. 4. 平均血淸 A/G比는 0.91(0.43∼2.64)이었으며 年令의 增加에 따라서 漸漸 증가하는 傾向이 있었다. 5. 平均血淸 cholesterol量은 179.38(46.4∼336.0)g/100㎖이었으며 年令의 增加에 따라 增加하여 4年牛를 頂点으로 다시 下向의 傾向을 나타내고 있었다. 6. 平均血淸 glucose量은 39.38(27.0∼57.3)㎎/100㎖로 낮았으며 年令別로 特徵的인 것은 發見할수 없었다. 7. 平均血淸 magnesium量은 2.72(0.20∼8.46)㎎/100㎖이었으며 老令牛에서 magnesium의 減少가 顯著하였다. 8. 平均血淸 calcium量은 8.69(6.34∼16.83)㎎/100㎖로 全般的으로 낮은 량이었으며 年令別 差異는 認定할수 없었다. 9. 平均血淸無機燐量은 5.88(3.50∼9.76)㎎/100㎖이었으며 年令別로 特徵的인 것은 發見할수 없었다. 10. 平均血淸Ca/P比는 1.48(0.68∼2.64)이었으며 年令別로 特徵的인 것은 發見할수 없었다. 11. 平均血淸 potassium量은 18.95(13.69∼24.24)㎎/100㎖이었으며 年令別 差異는 認定할수 없었다. 12. 平均血淸 sodium量은 315.90(282.86∼361.05)10.20)㎎/100㎖이었으며 年令別로 特徵的인 것은 發見할수 없었다. 13. 平均血淸 chloride量은 354.64(299.97∼361.05)㎎/100㎖이었으며 年令別 差異点은 發見할수 없었다. The present study was conducted to determine the blood chemical values of adult Holstein cows in Korea. Samples of blood were taken from 385 healthy cows in Chonnam province, and the results obtained are summarized as follows. 1. Mean serum totalprotein content was 7.35(5.10∼10.20)g/100㎖;it in creased with age. 2. Mean serum albumin content was 3.51(1.40∼4.40)g/100㎖;no differences were found between age groups in the serum albumin content. 3. Mean serum globulin content was 3.84(1.40∼7.20)g/100㎖; it increased with age. 4. Mean serum albumin/globulin ratio was 0.91(0.43∼2.64);it decreased with age. 5. Mean serum glucose concentration was 179.38(46.4∼336.0)g/100㎖;it increased up to 4 years of age and thereafter it decreased with age. 6. Mean serum glucose concentration was 39.38(27.0∼57.3)㎎/100㎖, which was low compared with other results. No differences were found in the glucose concentration between age groups. 7. Mean serum magnesium concentration was 2.72(0.20∼8.46)㎎/100㎖;it decreased significantly in older cows. 8. Mean serum calcium concentration was 8.69(6.34∼16.83)㎎/100㎖, which was low compared with other results. No differences were found in the calcium concentrati on between age groups. 9. Mean serum inorganic phosphate concentration was 5.88(3.50∼9.76)㎎/100㎖;no differences were found in the inorganic phosphate concentration between age groups. 10. Mean serum calcium/phosphate(Ca/P) ratio was 1.48(0.68∼2.64);no differences were found in the Ca/P ratio between age groups. 11. Mean serum potassium concentration was 18.95(13.69∼24.24)㎎/100㎖;no differences were found in the potassium concentration between age groups. 12. Mean serum sodium concentration was 315.90(282.86∼361.05)10.20)㎎/100㎖;no differences were found in the sodium concentration between age groups. 13. Mean serum chloride concentration was 354.64(299.97∼361.05)㎎/100㎖;no differences were found in the cholride concentration between age groups.
