Resumo: | The objective of this study was to evaluate four sorghum ensilages under nitrogen rates, regarding the nfermentative characteristics, such as, dry matter content of original matter (DMom) and silage (DMs), crude protein of original matter (CPom) and silage (CPs), pH, tenors of the volatile fatty acids, densities of wadding (Dw) and opening (Do), productions of gas (Gas) and effluent (Efl). The experimental design was in randomized blocks in a 4×3 factorial arrangement with four replications. The cultivars used in this study were 1F 305, 0369 267, 0369 255 and BR 700, and the three rates of nitrogen under ammonium sulphate form were 0; 60 and 120 kg N.ha-1.The tenors of DMmo differed (P<0.05) among N rates and the evaluated hybrids, presenting a variation of 21.82 to 28.17%. Values of DMs only differed (P<0.05) between the hybrids 1F305 and 0369 267, with averages of 27.6 and 27.8%, respectively. The concentration of lactic acid differed (P<0.05) among cultivars and treatments varying from 3.60% to 4.55%. The tenors of acetic acid differed only for BR 700, varying from 1.29% to 1.52%. The tenors of propionic acid differed (P<0.05) among cultivars, varying from 0.17% to 0.24%. The densities Dw and Do of the experimental silos did not differ between the hybrids, except the 0369 255.KEYWORDS: fermentative parameters; nitrogen fertilization; pH; Sorghum bicolor; volatile fatty acids |

Utilizou-se o delineamento de blocos casualizados em esquema fatorial 4 x 3, com quatro repetições. Os cultivares foram 1F 305, 0369 267, 0369 255 e BR 700, sob três doses de N (0; 60 e 120 kg.ha-1). Foram observadas interações entre as doses de N e os híbridos avaliados em relação aos teores de MSmo, com variação de 21,82 a 28,17%. Os valores de MSs diferiram (P<0,05) apenas entre os híbridos 1F305 e 0369 267, com médias de 27,6 e 27,8%, respectivamente. A concentração de AL diferiu (P<0,05) entre cultivares e tratamentos com variação de 3,60% a 4,55%. Os teores de AC diferiram apenas para o híbrido BR 700 com média de l,4% e variação de 1,29% a 1,52%. O teor de AP diferiu (P<0,05) entre os cultivares com variação de 0,17% a 0,24%. Somente o híbrido 0369 255 diferiu (P<0,05) em relação a Den, com média de 509,9 kg.m-3, enquanto em função das doses de N avaliadas, foram observadas significâncias com as aplicações das doses de 60 e 120 kg.ha-1 de N, com médias de 371,2 e 378,3 kg.m³, para os respectivos tratamentos. Apenas o híbrido 0369 255 diferiu (P<0,05) em relação a Dab, com média de 454,9 kg.m-3, enquanto a dose equivalente à aplicação de 120 kg.ha-1 de N diferiu (P<0,05) para todos os genótipos, com média do tratamento de 409,9 kg.m³.PALAVRAS-CHAVE: ácidos graxos voláteis; adubação nitrogenada; padrão de fermentação; pH; Sorghum bicolorUniversidade Federal de Goiás2011-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResarchAvaliado por paresPesquisaapplication/force-downloadtext/htmlhttps://revistas.ufg.br/vet/article/view/54010.5216/cab.v12i3.540Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 12 No. 3 (2011); 383-391Ciência Animal Brasileira / Brazilian Animal Science; v. 12 n. 3 (2011); 383-3911809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/540/9652https://revistas.ufg.br/vet/article/view/540/9653França, Aldi Fernandes De SouzaOliveira, Régis De PaulaMiyagi, Eliane SayuriDa Silva, Alzira GabrielaPerón, Hugo Jayme M.
