Nutritive value of mixed cattle feces with several levels coconut residues fermented by EM4. This experiment used a completely randomized design of 4 treatment levels coconut waste (0, 10%, 20% and 30%), with 4 replicates in each treatment. All of treatments added 0.3% EM4 was activated and fermented semiaerob during 4 days. Physically the fermentation process were indicating a good process. As a whole it can be concluded that increasing of coconut residues levels up to 30% resulted in increasing estrac eter, while the contents of crude fiber and crude protein reduced significanly.
