PENAMPILAN PRODUKSI SAPI PERANAKAN ONGOLE DAN PERANAKAN LIMOUSIN JANTAN DENGAN PAKAN KONSENTRAT DAN JERAMI PADI FERMENTASI (PERFORMANCE OF ONGOLE CROSSBRED AND LIMOUSIN CROSSBRED CATTLE WITH CONCENTRATE AND FERMENTATION RICE STRAW FED)

Abstract

The study was conducted to obtain performance of Ongole crossbred (OC) and Limousin crossbred (LC) cattle with concentrate and fermentation rice straw fed. Four males of OC cattle with initial weight 108,5 + 11,81 kg and four males of LC cattle with initial weight 133,25 + 18,84 kg, aged around 8-11 months, were used in this study. They were fed concentrate amount as 70% of dry matter (DM) requirement, and fermentation rice straw ad libitum. The experiment was designed on Independent Sample Comparison, and the data were analyzed by the use t-test. The results showed that total DM, concentrate DM, total crude protein (CP), concentrate CP intake, and average daily gain (ADG) signifficantly different (P<0,05) between the breeds. Fermentation rice straw DM, fermentation rice straw CP, total digestible nutrients (TDN) intake, and feed conversion were not signifficantly different (P<0,05) between the breeds. In OC cattle, the intake of total DM, concentrate DM, fermentation rice straw DM, total CP, concentrate CP, fermentation rice straw CP and TDN were 3.21 kg; 2.01 kg; 1.20 kg; 0,39 kg, 0,29 kg, 0,10 kg and 1.98 kg, respectively. In LC cattle, the intake of total DM, concentrate DM, fermentation rice straw DM, total CP, concentrate CP, fermentation rice straw CP and TDN were 4.18 kg; 2.84 kg; 1.34 kg; 0,51 kg, 0,40 kg, 0,11 kg and 2.74 kg, respectively. ADG between OC cattle and LC cattle were 0.24 kg and 0.47 kg, respectively, while feed conversion were 17.41 and 9.34, respectively. It was concluded that the performance of LC cattle on feed with concentrate and fermentation rice straw better than OC cattle.
