Abstract: Foram estudadas silagens de quatro híbridos de sorgo, com diferentes teores de umidade no colmo combinados com teor alto ou baixo de tanino, feitas em silos de tubos "PVC" em laboratório, lacrados com fita crepe e dotados de uma válvula tipo Bunsen. Usaram-se 24 tratamentos com 4 repetições cada, sendo 4 híbridos (T1=colmo suculento e baixo tanino, T2=colmo seco e baixo tanino, T3=colmo seco e alto tanino, T4= colmo suculento e alto tanino) combinados com 6 tempos para abertura do silo, sendo o primeiro tempos… Show more

“…Reduced DM digestion, which is associated with tannin concentrations in sorghum silages, has been observed in vitro (Cummins, 1971;Arora et al, 1975;Montgomery et al, 1986) and in vivo (Ben-Ghedalia and Tagari, 1977). However, more recently, Rodriguez et al (1999) and Carneiro et al (2006), who worked in vitro, and Oliveira et al (2007) and Machado et al (2011), who worked in vivo, similarly to the present study, did not find any effect of tannin levels in sorghum silages on DM digestibility. The absence of tannin effects on DM digestibility in the recently performed studies is most likely due to the lower tannin concentrations of the new bird resistant sorghum hybrids that were evaluated.…”
