Abstract

Look like in another tropical region, Indonesia have high both ambient temperatures and solar radiation during the year, this condition is limited factor and unfavorable for livestock covered thick hair like sheep. Comfort zone temperature for sheep ranges from 15 to 30 °C, and the critical temperature is above 35 °C. Temperatures higher than the upper critical point can affect both physiological and production performance of animal. . Hot climates may increase energy requirements for maintenance by 7–25%, by inducing a rise in body temperature and breath rate. The objective of this research are to investigation of physiological profiles such as respiration rate, hearte pulse and rectal temperature Padjadjaran sheep. Twenty ram Padjadjaran weighing between 25 to 47.5 kg used in the present study were came from sheep breeding station at Purwakarta – West Java – Indonesia. The variable measure are respiration rate (RR), pulse rate (PR) and rectal temperature (RT). The data collected in two condition environment, morning and afternoon. The respiration rate recorded by counting flank movements per minute from a non-obstructive distance; the pulse rate measured by fingered the pulses of the vena femoralis for one minutes; and the rectal temperature is measured by inserting a digital thermometer into the rectum as deep as 3 cm, hold until makes a beep. Data analysis use descriptive methods.
In the morning, average of RR, PR and TR are 32.49, 55,51 and 38.47OC respectively, while in the afternoon 82.75, 66,35 and 40.14OC. According to Silanikove (2000), based on respiration rate, 85 percent ram no indicate heat stress in the morning, while in the afternoon 60 percent ram indicate high level heat stress. The conclusion, in the afternoon ram need shading or protecting roof for minimize sun exposure.
