Hematology, Heart Rate, Respiration Rate, and Body Temperature Values of Lactating Dairy Cattle in Pangalengan

Abstract

ABSTRAK Pangalengan terletak di wilayah pegunungan dengan ketinggian 1.0001.420 dpl, yang memiliki rataan temperatur sekitar 17,80 ± 1,46 C dan kelembapan 63,99 ± 2,74%. Kondisi ini sangat mungkin memengaruhi nilai fisiologis sapi perah, terutama selama periode laktasi. Namun demikian, informasi tentang nilai fisiologis sapi laktasi di Pangalengan sampai saat ini belum tersedia. Penelitian ini menggunakan 20 ekor sapi perah, dan nilai fisiologis diukur pada pagi, siang, dan sore hari. Kisaran frekuensi denyut jantung, respirasi, dan temperatur rektal sapi perah laktasi secara berturut-turut adalah 59,8272,02 kali/min, 26,0136,69 kali/min, dan 37,3238,36 C. Kisaran nilai hemoglobin, hematokrit, eritrosit, dan leukosit sapi perah laktasi secara berturut-turut adalah 8,299,51 g/dl, 24,5229,70%, 6,108,18 juta/µl, dan 6.22010.600 sel/µl. Kisaran nilai diferensial leukosit sapi perah laktasi ialah limfosit 32,6463,14%, neutrofil 28,3453,24%, monosit 0,414,85%, eosinofil 1,5815,78%, dan basofil 0%. Kisaran rasio N/L pada sapi perah laktasi adalah 0,141,63. Studi ini menyimpulkan bahwa sapi perah laktasi yang dipelihara pada kondisi iklim Pangalengan yang sejuk masih menunjukkan nilai fisiologis yang berada dalam kisaran normal. ABSTRACT Pangalengan is located in the high land region with an altitude of 1.0001.420 m above sea level, which has an average temperature of 17.80 ± 1.46 C and humidity of 63.99 ± 2.74%. These environmental conditions will affect the physiological values of dairy cattle, especially during the lactation period. However, information about the physiological parameters of lactating cows in this area is not available. This study used 20 lactating dairy cows, and physiological values were measured in the morning, midday, and afternoon. The ranges of heart rate, respiration rate, and rectal temperature of dairy cows during lactation period were 59.8272.02 times/min, 26.0136.69 times/min, and 37.3238.36 C, respectively. The range of hemoglobin, hematocrit, erythrocytes, and leukocytes of lactating dairy cows was 8.299.51 g/dl, 24.5229.70%, 6.108.18 million/µl, and 6.22010.600 cells/µl, respectively. The range of differential leukocyte of lactating dairy cows were lymphocyte 32.6463.14%, neutrophils 28.3453.24%, monocytes 0.414.85%, eosinophils 1.5815.78%, and basophils 0%, respectively. The range of a ratio of N/L of lactating dairy cows was 0.411.63. This study concludes that lactating dairy cows maintained under mild Pangalengan climatic conditions still show physiological values within the normal range.
