N2  - In Mexico, maize silage generally has low energetic values in comparison to silage from the USA and Europe. This has been attributed to the selection emphasis on forage yield without considering nutritive value (Nunez et al. 2001). To improve silage quality, it is necessary to select the best hybrids with both characteristics. There is sufficient evidence of hybrid differences in crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and dry matter digestibility (DMD) (Allen et al.1995). The range of 25 to 35% for ADF; 40 to 52% for NDF; more than 1.45 Mcal/kg for lactancy net energy (ENL); and more than 65 % of DMD are acceptable at the Comarca Lagunera (Herrera 1999). The objective of this study was to evaluate quality protein maize (QPM) hybrids for silage production and quality in the principal milk production region of Mexico
