ABSTRACT
Bali cattle are local cattle owned by Indonesia that play a role in meeting the lack of meat demand in the country. In its development, both horned and hornless Bali cattle were found. This study aims to determine the influence of heat stress on the physiological and hematological profiles of horned and polled Bali cattle. Eight male Bali cattle (four horned and four polled) with an age range of 2.5–4.5 years were used. Parameters observed were the body’s physiological response (rectal temperature, skin surface temperature, respiration rate, and pulse rate) and hematological profile (erythrocytes, hemoglobin, hematocrit, and leukocytes). Body physiological and hematological data were analyzed using factorial analysis to compare Bali cattle (horned and polled) and the time factor of measurement (morning and afternoon), followed by Duncan’s test. The results showed that horned and polled Bali cattle were significantly (P<0.05) different in rectal temperature, erythrocytic counts, hemoglobin levels, and hematocrit values but not in skin surface temperature, respiration rate, pulse rate, and leukocyte counts. The time factor of measurement (morning and afternoon) showed significant (P<0.05) differences in rectal temperature, skin surface temperature, respiration rate, pulse rate, erythrocyte counts, and hemoglobin levels, but not in hematocrit values and leukocytic counts. Compared to horned Bali cattle, polled Bali cattle showed higher increases in rectal temperature, skin surface temperature, and respiration rate caused by the absence of horns. A higher hematological profile supports higher metabolic processes.
