Physiological Values of Dairy Cattle during Dry Period in Pangalengan: Hematology, Heart Rate, Respiration Frequency, and Body Temperature

Abstract

Pangalengan is at an altitude of 1000?1400 m above sea level with annual temperatures range of 12?28°C and annual humidity of 60?70%. Pangalengan's environmental conditions can affect the physiological conditions and health of dairy cattle, especially during the dry period. The information about the physiological value of dairy cows when they are in a dry period is not yet available. This study used 46 dairy cows that were on a dry period, and measurements of physiological parameters were carried out in the morning, afternoon, and evening. Heart rate, respiration rate, and body temperature ranges were 52,8?70,2 times/min, 18.9−36.6 times/min, and 37,6?38,6°C, respectively. The ranges of hemoglobin, hematocrit, erythrocytes, and leukocytes were 9.3?11.3 g/dl; 30.4?36.6%; 6.5?8.70 million/µl; and 7.4?12.8 thousand/µl, respectively. The differential ranges of leukocytes including lymphocytes, neutrophils, monocytes, eosinophil, and basophils were at 29.60?55.60%; 28.80?56.20%; 0.30?4.30%; 5.50?19.7%; and 0.00?0.00%, respectively. The neutrophil/lymphocyte ratio was obtained in the range of 0.45?1.91. This study concluded that dairy cows during dry period maintained in mild Pangalengan climatic conditions showed physiological values that were within the normal range. Keywords:
