Income over feed cost of Aceh cattle fattened with forage and concentrate in different levels

Income over feed cost (IOFC) is needed to evaluate and analysis of beef cattle fattening enterprise. This study aims to determine the IOFC of Aceh cattle fattened with forage and concentrate on different levels. The research was conducted on May-August 2018 in Livestock Breeding Center of Aceh. Twenty males Aceh cattle aged 1.5 to 2.5 years were grouped 4 treatments based on different forage and concentrate levels (T1=100:0, T2=70:30, T3=50:50 and T4=30:70) and intensively kept for 3 months. Average daily gain, feed intake, feed conversion, feed efficiency, feed cost per gain and IOFC were calculated and statistically analyzed by one way of ANOVA, followed by Duncan's New Multiple Range Test. The result showed that concentrate feed increased (P <0.05) the dry matter intake, average daily gain and feed efficiency. The feeding by concentrate (T2, T3, T4) decreased (P <0.05) feed cost per gain Rp.14,894 and increased (P <0.05) IOFC Rp.8,715. The feed efficiency and IOFC of T3 had the highest (P <0.05). The conclude our finding, farmers of Aceh cattle are benefited from feeding concentrate as a supplement in fattening. The best level of concentrate supplementation on forage feed is 50:50.
