The results showed that the harvesting date posed various effects on quality and yield of silage maize. With the postponement of harvesting date, silage maize exhibited continuously increasing dry weight and gradually declining fresh weight; in maize straws, ADF and NDF contents increased constantly, crude protein content and IVODM decreased gradually, crude fat content increased first and then declined; in maize kernels, crude protein and lysine contents decreased continuously, crude starch content increased gradually, crude fat content increased first and then reduced. In conclusion, silage maize should be harvested at 27-34 d after pollination.展开更多
