This study set, assess barley silage enriched pulque (fermented agave sap), molasses  and added with aerobic and anaerobic bacteria with prebiotic activity, for this procedure, became 10 different treatments in packed barley forages.

The results showed that the treatments were evaluated with anaerobic microorganisms generated ensiled with pleasant organoleptic characteristics, where visibly forage materials were slightly smoothed and fragmented at the end of the ensiling process, and generally had a darker color to the the start of fermentation, fiber evaluations were adequate, the data showed the pH was low, contrary to what happened with aerobic treatments.

Compared with control, materials supplemented with molasses and pulque possible to reduce moisture loss, the values reported for dry weight were supplemented materials and 0.7g to 0.5g control. Bromatologic test results regarding the analysis of crude fiber, show that fermented sap of agave (pulque) generated a greater amount of crude fiber obtained percentages were 70%, 60% molasses and 50% Control, combinatorial treatments pulque + molasses also showed values of 70%, show high values fodder crude fiber because it has implications for fertilization of forages during growth.

We conclude that molasses supplements normally used in processes of silage and also adding pulque which can be used as a supplement, allows a greater activity of lactic acid bacteria with prebiotic activity in the silage, and also allow for the fiber ensiling mayorme this can be largely quantifiable and therefore digestible animal feed.
