Abstract

<em>This study was aimed to determine the effect of protected soybean groats-Lemuru fish oil in the diet on performance of males Simental Ongole Crossbred. The materials used in this study were 9 heads of males Simental Ongole Crossbred cattle with an average initial weight of 467.55 ± 30.89 kg. The experimental design used was a completely randomized design (CRD) consisting 3 treatments and 3 replications. The treatments were P0 = 30% rice straw fermentation + 70% basal concentrate; P1 = 30% rice straw fermentation + 55% basal concentrate + 15% ogf unprotected soybean groats-lemuru fish oil, and P2 = P1 = 30% rice straw fermentation + 55% basal concentrate + 15% of protected soybean groats-lemuru fish oil. Data were analyzed using analysis of variance followed by Duncan's Multiple Range Test. The results showed that the use of protected soybean groats-lemuru fish oil in the diet did not affect the initial body weight, final body weight, average daily gain, FCR and FER. Additionally, the treatment significantly affected dry matter intake and the income of the feedlot has increased. Conclusions of this study was the use of 15% protected soybean groats-lemuru fish oil in the diet increased production performance and income of male simental Ongole Crossbred feedlot.</em>
