The use of preserved foods as silage, data from the beginning of the century, when the goal was ensure food for animals during pasture scarcity. Currently, silage ceased to be considered an alternative food and has became necessary to achieve high levels of production. Silage can be made from any forage since respected some requirements, which guarantee good fermentative process inside the silo. Although few discussed, the legumes silage has awaken researcher’s interest worldwide. The main legumes in Brazil for this purpose is soybean (Glycine max L. Merril) by having high concentrations of protein, energy and potentially digestible fiber, therefore his management being consolidated on all country. Studies suggests the potential use of plant soybean silage (cultivars, harvest period and chemical composition), in ruminant feeding. However, few has tested the effect for animal performance, and the results are not fully consistent. The objectives of this study are: experiment 1: to evaluate the effect of the inclusion of powder molasses and microbial inoculant associated with different harvesting of soybean crop for silage production and; experiment 2: to evaluate the effect of increasing levels of soybean silage in lactating dairy cows diet on intake, apparent total digestibility, milk production and composition, ruminal fermentation, milk fat acids profile, blood parameters, microbial protein synthesis, nitrogen balance and feeding behavior. The hypothesis of present study are: 1) the soybean silage could partially replace corn silage in lactating dairy cows diet without change the consumption of nutrients and milk production. (AU)
