Effect of Minerals S, P and Cassava Flour Leaf Supplemented with Ammoniation Palm Leaves on the Performance of Beef Cattle

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
