Resumo: | The objective of this study was to evaluate the chemical composition, quantitatively characterize, in a comparative way, the carbohydrate fractions of commercial corn hybrids and of materials from crossing between hybrids for silage production. Therefore, 14 multiple hybrids, 7 commercial hybrids, 7 selffertilized from commercial hybrids progenies and 2 controls were evaluated in two agricultural years. The 2B710 hybrid showed high dry matter in vitro digestibility in the first year and fiber fraction in the two years of evaluation. The progeny P30P34 x P30P34 showed high dry matter digestibility and fiber fraction in two years. The highest fraction of non-fibrous carbohydrates (A+B1) was found for the crosses IMPACTO x CD308 and P30R50 x CD308 for the first and second year respectively, indicating a greater efficiency in providing readily available energy in the rumen. The significant interactions between corn hybrids and agricultural years for chemical composition showed that the growing environment has great influence on the nutritional composition, leading to the necessity of evaluating multiple environments in order to select corn for silage production. |

Para tanto, foram avaliados 14 híbridos múltiplos, sete híbridos comerciais, sete progênies autofecundadas de híbridos comerciais e dois testemunhas em dois anos agrícolas. O híbrido 2B710 apresentou alta digestibilidade “in vitro” da matéria seca no primeiro ano e da fração fibrosa nos dois anos de avaliação. A progênie P30P34 x P30P34 destacou-se pelos altos valores de digestibilidade da matéria seca e da fração fibrosa nos dois anos avaliados. A maior fração de carboidratos não-fibrosos foi encontrada para os cruzamentos IMPACTO x CD308 e P30R50 x CD308 no primeiro e no segundo ano, respectivamente, indicando, maior eficiência em fornecer energia prontamente disponível no ambiente ruminal. As interações significativas entre híbridos de milho e ano agrícola para a composição químico-bromatológica, evidenciaram que o ambiente de cultivo tem grande influência sobre a composição nutricional, levando à necessidade de avaliação em diferentes ambientes para fins de seleção de milho visando à produção de silagem.UEL2014-12-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo científicoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1455810.5433/1679-0359.2014v35n6p3249Semina: Ciências Agrárias; Vol. 35 No. 6 (2014); 3249-3262Semina: Ciências Agrárias; v. 35 n. 6 (2014); 3249-32621679-03591676-546Xreponame:Semina.
