Abstrak: The experiment was conducted to evaluate the influence of levels Brachiaria humidicola grass and cassava hull on slaughter weight, carcass and non carcass weight of male thin tail sheep. Twelve yearling male thin tail sheep with initial body weight 19,06 ± 1,46 kg were treated as followed P0= 100% Brachiaria humidicola grass, P1=20% cassava hull + 80% Brachiaria humidicola grass, P2= 40% cassava hull + 60% Brachiaria humidicola grass, dan P3= 60% cassava hull + 40% Brachiaria humidicola grass. Data gathered on slaughter weight, empty weight, carcass weight, non carcass weight and carcass percentage, were analyzed using Anova for Complete Randomized Design, followed by Duncan’s test. Result of the study showed that the addition of cassava hull did not influence of slaughter weight, empty weight, carcass weight and non carcass weight (P>0,05), but influences significantly carcass percentage (P<0,05). The average carcass percentage of P0, P1, P2, P3 were 36,46%; 38,41%; 43,23%; 44,54% respectively. It can be concluded that the addition of cassava hull until 60% increased carcass percentage of thin tail sheep, but did not increased slaughter weight, empty weight, carcass weight and non carcass weight of male local sheep.

Judul: Respon Fisiologis Domba Ekor Tipis Jantan yang Diberi Pakan Rumput Brachiaria humidicola dan Kulit Singkong pada Level yang Berbeda
Abstrak: The body condition of livestock is affected by physiological process which is stimulated by environmental changes such as weather, nutrition and management factors. The main objective of this research is to observe physiological response of male indigenous local sheep given different level of Brachiaria humidicola grass and cassava hull. Twelve yearling male indigenous local sheep with initial average body weight 19,06 ± 1,46 kg were used in this research. Dietary treatments consisted of R0: 100% Brachiaria humidicola + 0% cassava hull, R1 : 80% Brachiaria humidicola + 20% cassava hull, R2: 60% Brachiaria humidicola + 40% cassava hull, R3: 40% Brachiaria humidicola + 60% cassava hull. The parameters observed were rectal temperature, frequency of respiration, and heartbeat. Both indoor and outdoor microclimate had been measured (temperature and humidity). Randomized Complete Design with three repetition was used to analyze the data, and any significant differences were further tested by using Duncan’s test. The experimental showed that result were not significant (P>0,05) to rectal temperature, frequency of respiration and heartbeat. It is concluded that the use of cassava hull in feed must be more carefully because of HCN as limited factor and its possible negative effect on sheep physiology response.
