Planning of experiments this time conducted trials planned. Random blog (Randomized Complete Block Design, RCBD) Experiment in the broiler for 2 weeks the number 80 is divided into 4 groups each with 5-7 when at repeated last week, so a random number of broiler from 4 groups of 4 each, repeated each trials supplementing dregs fermentation the yeast in this recipe it's broiler in levels 0, 5, 10, and 15 percent are two experimentation breaks check box.Great DL 01 hotkeys, experimental studies on fermentation of Saccharomyces cerevisiae with cassava can improve or palatability by element or palatability of cassava with 2.8 percent of protein from 18.08 percent are using 30-day fermentation period, which will see the cassava fermentation has higher protein content 15.28 percent when compared with a normal of cassava.
