Title A name given to the resource Rendimento e composição químico-bromatológica de fenos triturados de gramíneas tropicais Yield and chemical composition of chopped tropical grass hays Creator An entity primarily responsible for making the resource Emerson Moreira de Aguiar, Guilherme Ferreira da Costa Lima, Mércia Virgínia Ferreira dos Santos, Francisco Fernando Ramos de Carvalho, Adriana Guim, Henrique Rocha de Medeiros, Aurinês Queiroz Borges Description An account of the resource A pesquisa foi conduzida objetivando avaliar o rendimento, a composição químico-bromatológica e as perdas de fenos triturados de milheto, sorgo sudanense, capim-elefante e sorgos forrageiros (SF-25 e IPA-467-4-2). Os materiais foram colhidos quando atingiram 30% de inflorescências, com exceção do capim-elefante, colhido aos 60 dias. Utilizou-se delineamento de blocos completos casualizados, com cinco tratamentos e quatro repetições. Houve diferenças significativas, com maiores produções de feno para os sorgos IPA-467-4-2 (10,85 t/ha/corte) e SF-25 (10,65 t/ha/corte), que foram superiores ao capim-elefante, sorgo sudanense e milheto, com, respectivamente, 6,94; 6,69 e 4,93 t/ha/corte. Os percentuais de perdas na fenação não diferiram entre os tratamentos, com níveis variando de 17,33 a 20,17%. Os fenos de milheto e sorgo sudanense tiveram as maiores concentrações de PB (10,56 e 8,80%), superiores às do capim-elefante (6,76%) e dos sorgos SF-25 (5,62%) e IPA-467-4-2 (5,50%). Os valores de FDN foram, na maioria, superiores a 70,0%. As menores concentrações de NIDN foram observadas nos cultivares de sorgo (0,42 e 0,40% da MS). As concentrações de NIDA variaram de 0,06 a 0,30% na MS. As maiores concentrações de lignina (%MS) dos fenos foram obtidas no milheto (6,52%) e no sorgo IPA-467-4-2 (6,17%). As concentrações de nutrientes digestíveis totais estimadas (NDTe) dos fenos diferiram significativamente, com o maior valor para o sorgo sudanense (53,35%). Os fenos triturados das gramíneas tropicais avaliadas apresentaram rendimentos elevados e composição químico-bromatológica dentro dos padrões mínimos recomendáveis para nutrição de ruminantes.The research was carried out to evaluate yield, chemical composition and losses of chopped tropical grass hays with the following forages: pearl millet (Pennisetum americanum), sudangrass (Sorghum sudanense), elephantgrass (Pennisetum purpureum) and two cultivars of forage sorghum (SF-25 and IPA-467-4-2) (Sorghum bicolor). The materials were harvested at 30% flowering, except for elephantgrass (60 days). The experiment was conducted according to a complete randomized block design, with five treatments and four replications. There were significant differences among hay productions with sorghum cultivars IPA-467-4-2 and SF-25 reaching the highest yields (10.85 and 10.65 t/ha/cut). Production of elephantgrass, sudangrass and pearl millet hays were respectively of 6.94, 6.69, and 4.93 t/ha/cut. Percentage of hay losses were not different among all treatments and varied from 17.33 to 20.17%. Pearl millet and sudangrass hays had the highest CP concentrations (10.56 and 8.80%), which were superior to elephantgrass (6.76%) and sorghum cultivars (5.62 and 5.50%). Most of the NDF values were superior to 70.0%. Sorghum cultivars exhibited the lowest NDIN concentration (0.42 and 0.40% of DM). The ADIN concentration ranged from 0.06 to 0.30% of DM. The highest lignin (%DM) concentration was observed for pearl millet (6.52%) and sorghum IPA-467-4-2 (6.17%) hays. Estimated TDN of the hays showed significant differences and sudangrass reached the highest value (53.35%). Production of chopped tropical grass hays showed high yields and chemical composition according to the minimum standards for ruminant nutrition.
