Resumo: An experiment with pearl millet (Pennisetum glaucum) cv ADR-300 under nitrogen doses (0, 50, 100 and 150 kg.ha-1) at two residual height cuts (0.20 and 0.25 m) was carried out to evaluate dry matter production and chemical composition. The experiment was carried out at Universidade Federal de Goiás. The experimental design used was randomized blocks in a 4 x 3 factorial arrangement, with three replications. Dry matter production (DMP), dry matter content (DM), crude protein (CP), acid detergent fiber (ADF) and neutral detergent fiber (NDF) were evaluated. The DMP differed (P<0.05) among the N doses and cuts. DM content decreased as N doses increased. The addition of N doses promoted a rise of CP content at all the cuts. CP content decreased with the cuts succession. The NDF tenors differed (P<0.05) with the succession of the cuts at both heights. The ADF values (P<0.05) differed in function of the addition of N doses and the succession of the cuts. Pearl millet showed production and chemical composition variation in the performed treatments, thus, it is recommended for animal feeding that this forage plant is used at the residual height of 0.25 m and with application of a N dose of 150 kg.ha-1.KEYWORDS: crude protein; dry matter production; nitrogen; Pennisetum glaucum; residual height.

ADR-300 sob doses de nitrogênio (0, 50, 100 e 150 kg.ha-1) em regimes de cortes em duas alturas residuais (0,20 e 0,25 m), para se avaliar o potencial de produção e composição bromatológica da massa seca. O trabalho foi conduzido na Escola de Veterinária /UFG. O delineamento experimental foi o de blocos casualizados em esquema fatorial 2 x 3 x 4, com três repetições. Avaliou-se a produção de massa seca (PMS), teor de matéria seca (MS), proteína bruta (PB), fibra em detergente neutro (FDN) e fibra em detergente ácido (FDA). A PMS diferiu (P<0,05) entre as doses de N e cortes de avaliações. Houve decréscimo no teor de MS à medida que as doses de N se elevaram. O acréscimo das doses de N promoveu uma elevação dos teores de PB do milheto, em todos os cortes. Houve decréscimo no teor de PB com a sucessão dos cortes. Os teores de FDN e FDA diferiram (P<0,05) com a sucessão dos cortes em ambas as alturas. Houve variação na produção e composição bromatológica do milheto mediante os tratamentos aplicados, assim, recomenda-se para a alimentação animal a utilização dessa planta forrageira na altura residual de 0,25 m e com aplicação da dose de 150 kg.ha-1 de N.PALAVRAS-CHAVE: altura residual; nitrogênio; Pennisetum glaucum; produção de massa seca; proteína bruta.Universidade Federal de Goiás2012-03-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/143410.5216/cab.v13i1.1434Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 13 No. 1 (2012); 67-75Ciência Animal Brasileira / Brazilian Animal Science; v. 13 n. 1 (2012); 67-751809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/1434/10588https://revistas.ufg.br/vet/article/view/1434/10589Da Silva, Alzira GabrielaDe Farias Júnior, Oscar L.de S.
