LEHMEN, Rosilene Inês; FONTANELI, Renato Serena; FONTANELI, Roberto Serena  and  SANTOS, Henrique Pereira dos. Yield, nutritive value and fermentative parameters of winter cereals silages. Cienc. Rural [online]. 2014, vol.44, n.7, pp.1180-1185. ISSN 0103-8478.

The study was carried out to evaluate the forage yield for ensilage, nutritive value and fermentative parameters for winter cereals silages. It was evaluated twelve winter annual grasses genotypes: white oat URS 21, URS Guapa and Barbarasul, wheat BRS Tarumã and BRS Umbu, triticale Embrapa 53 and BRS Minotauro, rye BRS Serrano, barley BRS Cauê and black oat BRS 139-Neblina, IAPAR 61-Ibiporã and Ucrânia. The genotypes were ensiled at dough grain to firm mass stages, with 30 at 35% dry matter, and packaged, for ninety days, in PVC experimental silos. The design was a randomized complete block, with three replications. All genotypes evaluated present satisfactory characteristics for ensilage. The BRS Serrano rye presented greater biomass yield. The BRS Cauê barley, BRS Umbu wheat and UFRGS 19, URS Fapa-Slava and UPF 16 white oats present higher crude protein concentrations.

Keywords : conserved forage; ammonia nitrogen; pH; crude protein.
