EVALUATION OF MEXICAN NATIVE AND HYBRID MAIZE (ZEA MAYS) SILAGES FOR SUSTAINABLE MILK PRODUCTION

<p><strong>Background</strong>. Maize cultivation and dairy cattle represent two of the main economic activities in Mexico. <strong>Objective</strong>. Determine forage yield (ton / ha) quality maize silage produced Mexico estimate potential milk production. <strong>Methodology</strong>. For this purpose, 13 studies carried out Mexico, were analyzed according to study area (north vs. center Mexico) variety (native hybrid). inclusion final database, should have been including agronomic chemical variables such as: dry matter (DMY) ha), plant density (number plants content (DM), crude protein (CP), neutral detergent fiber (NDF), ash or organic (OM), digestibility (DMD), (NDFD), starch fat content. The data using a completely randomized statistical design. <strong>Results</strong>. DMY (dry yield) ha, production DM higher (P <0.0001) for central region with respect northern region. Regarding (kg milk/ native silages more <0.05) than hybrids. A positive correlation was observed NEL (net energy lactation) (MJ kg DM) ton DM. <strong>Implications</strong>. thus has provide greater ha Milk/ per hybrid maize, due NDF that causes NEl.<strong> Conclusions.</strong> use is viable alternative as feed cows, hectare compared maize.</p>
