Effects of biological organic fertilizer on feeding value of Mexico corn

This test studied effects of four biological organic fertilizer concentration 0 (CK), 50，60 and 70 kg667 m-2 for Mexico corn growth characteristics and grass nutrients and feeding value. The results showed that Mexico corn leaf length, plant height and fresh hay yield, crude protein (CP) and crude fat (EE), digestibility of dry matter (DDM), free feed intake (DMI) and relative feeding value (RFV) were increased significantly (P0.05), the crude ash (CA), acid washing fiber (ADF) and neutral detergent fiber were(NDF) reduced significantly (P0.05) with the increasing of the concentration of biological organic fertilizer. Therefore, biological organic fertilizer can increase Mexico maize yield, grass nutrients and feeding value.
