TINGKAH LAKU INDUK SAPI SIMMENTAL PERANAKAN ONGOLE DIBANDINGKAN SAPI PERANAKAN ONGOLE DI DAERAH TROPIS

Abstract

This research was carried out to observe the behavior and physiological response of Simmental Ongole Crossbred (Simpo) cow compared to Ongole Crossbred (PO) cow in the tropical area. Three � 4 years old of 5 Simpo cows and 5 PO cows were used in this research, all of cows were not pregnant. The research carried out in October 2012 at Laboratory of Meat, Drought and Companion Animal, Faculty of Animal Science, Gadjah Mada University. The parameter included temperature and humidity of the stable, physiological data (respiration frequency, puls e frequency, and rectal temperature), feed and water consumption, as well as behavior data (standing frequency, sitting frequency, eating frequency, drinking frequency, defecating frequency, urinating f requency, ruminating frequency, ruminating duration, numbers of digest while ruminating) were observed. The data of behavior and consumption of feed and water were collected and analyzed used independent t-test. The data showed that the temperature and air humidity in research location were between 23 � 30°C and 58 � 81%. Feed consumption in Simpo cow was lower (P<0.05) than PO cow (121.14 ± 0.46 vs 123.08 ± 0.62 g/kg metabolic body weight (BBM)
