This study aims to determine the effect of refined palm leaves supplemented with mineral S and P and cassava leaves flour on cattle performance. This research is carried out starting from May 01 to September 15, 2015. Palm leaf sample, ration and feces are analyzed in Proximate and Van Soest at Ruminant Nutrition Laboratory of the Faculty of Animal Husbandry, University of Andalas, Padang. The research is an experimental study using randomized block design with 5 treatments and 4 replications. Treatment consists of: A = grass+concentrate (60:40%) as a control; B = best processed palm leaf in stage I+concentrate (60:40%); C = B+S and P mineral supplementation; D = B+cassava flour and E = C+cassava leaf flour. Data is analyzed using analysis of Variance (ANOVA). Differences between treatments were tested by Duncan's Multiple Range Test (DMRT). The results show that the treatment gave a significantly different effect on the performance of beef cattle (p<0.05). The results of the average consumption of dry matter ration ranged from 10.54 to 11.25 kg/head/day; Dry matter digestibility: 51.51 to 61.59%; body weight gain: 0.62 to 0.94 kg/head/day; ration efficiency: 5.74 to 8.36%. The results of the study can be concluded that ammoniation palm leaves supplemented with mineral S and P as well as cassava leaves flour can replace 100% grass feed of beef cattle and provide better performance than the control diet (grass) in terms of body weight gain.
