Weinberg et al. (2007) specifically showed that corn ensiled with L. buchneri 40788 resulted in improvement of in vitro ruminal aNDF digestion. However, this find- ing has not been consistent as some strains of L. buchneri added to the silages have not affected fiber digestion (Filya, 2003; Adesogan et al., 2003). An alternative mechanism to improve fiber digestibility of silages is to treat it with select strains of lactic acid bacteria that express ferulic acid esterase (Nsereko et al., 2008).
