Pseudoacacia and Caragana were significantly (P.05) better than A. fruticosa in pH, lactate content and ammonia-N/total-N ratio, so that their fermentation quality was better. In addition, they were high in crude protein and low in neutral detergent fiber and acid detergent fiber, showing that they were abundant in nutritive components. A. fruticosa was the inferior silage in every evaluation in the experiment. The mixed silage of R. pseudoacacia and Caragana was the best, and the mixed silage with A. fruticosa was not recommendable. There were no obvious changes in the time before and after silaging in nutritive value of these three kinds of plants, it showed that the silage technology was good.
