This workaims to evaluate nutritive value of fourteen cool‐season genotypes as pasture or silage .Material and methods The trial was conducted at Agronomy research station in Passo Fundo , Brazil . A randomized completeblock design replicated three times . The plots were composed by seven rows ０ .２ m apart and ５ .０ m long . Seeding date wasApril from ２００３ to ２００５ . The fertilizer applied was ２５０ kg / ha of ５‐２５‐２５ ( N‐P２ ０５‐K２０ ) plus ３０ kg N/ ha ( urea) at tillering andafter the harvest . The plants with ３０‐cm height average were clipped to a ７ .０‐cm stubble height . Nutritive value analized usingnear infrared spectroscopy ( NIRS) .Results The forage nutritive value on green tissue harvested was high . The average CP concentration was ２２ .８ ％ and thedigestibility was ６９ .１ ％ ( Table １ ) . The silage decreased CP concentration to ８ .９ ％ and the digestibility to ６１ .５ ( Table １ ) .Table 1 Crude p rotein ( CP ) , neutral detergent f iber ( NDF) , acid detergent f iber ( ADF) , and dry matter digestibility( DMD) concentration ( ％ ) o f winter cereals .Green forage SilageWinter cereals CP NDF ADF DMD CP NDF ADF DMDOat UPF １８ ２１ .５ efg ５０ .０ e ２３ .０ gh ７１ .０ ab ９ .５ abc ５８ .３ h ３２ .０ ６４ .０ abOat IPFA ９９００９ ２４ .０ abc ５２ .１ b‐e ２４ .９ c‐f ６９ .５ c‐f １０ .９ a ６５ .１ bcd ３７ .１ ab ６０ .０ deOat Agro Zebu ２５ .０ a ５０ .６ de ２３ .６ fgh ７０ .５ abc １０ .２ ab ６７ .３ ab ３９ .４ a ５８ .２ eRye BR １ ２３ .３ bcd ５２ .９ a‐d ２４ .７ d‐g ６９ .７ b‐e ８ .３ cd ６９ .２ a ３９ .０ a ５８ .５ eRye BRS Serrano ２２ .５ c‐f ５２ .３ b‐e ２５ .２ b‐f ６９ .３ c‐g ９ .０ bcd ６６ .７ abc ３７ .３ ab ５９ .８ deBarley BRS １９５ ２１ .０ fg ５０ .７ cde ２６ .６ abc ６８ .２ fgh ８ .３ cd ５９ .３ gh ３１ .９ e ６４ .１ aBarley BRS ２２４ ２０ .８ g ５２ .９ a‐d ２７ .７ a ６７ .３ h ７ .８ d ６１ .４ fg ３１ .８ e ６４ .１ aBarley BRS ２２５ ２２ .５ c‐f ５３ .２ abc ２６ .４ a‐d ６８ .３ e‐h ８ .９ bcd ６１ .０ fgh ３３ .０ de ６３ .２ abTrit .倡 BRS １４８ ２２ .８ b‐e ５３ .８ ab ２４ .３ e‐h ７０ .０ a‐d ８ .１ cd ６６ .１ a‐d ３５ .６ bc ６１ .２ cdTrit .
