Resumo: | This experiment was conducted at the Experimental Farm of the College of Veterinary Medicine and Animal Science - Unesp - Botucatu campus (SP), with the objective of evaluating the ensiling potential and chemical composition of corn plants submitted to different levels of ear removal at the milky stage, as well as measuring the quality of the silages obtained. A completely randomized design was used, with five treatments and three replicates. The treatments consisted of ensiling corn plants with or without saleable ears (SE), as follows: T1 - 100% SE; T2 - 75%; T3 - 50%; T4 - 25%; and T5 - without SE. The SE were harvested between 19 and 23 days after pollination (milky stage), and dry matter content and yield of different plant parts were measured. Harvest for ensiling occurred at the dough stage, at which time ensiling potential and chemical composition were determined. Silage quality was evaluated thereafter. SE removal did not affect (p>.05) either dry matter content at the milky stage or chemical composition at the dough stage. However, it changed (p.05) silage conservation. Dry matter content is the main limiting factor for ensiling corn after SE removal and it is possible to remove up to 25% SE at the milky stage, without lowering the nutritive value of plants to be ensiled at the dough stage. |

O delineamento experimental utilizado foi o inteiramente casualizado, com cinco tratamentos e três repetições. Os tratamentos consistiram na ensilagem das plantas de milho, com ou sem as espigas potencialmente comercializáveis na forma de milho verde (EPC), sendo: T1 - com 100%; T2 - com 75%; T3 - com 50%; T4 - com 25% de EPC; e T5 - sem as EPC. Entre 19 e 23 dias após a polinização, procedeu-se à colheita das EPC, estádio de grãos leitosos, avaliados quanto ao teor e produção de matéria seca das diferentes partes da planta. Quando as plantas atingiram o estádio de grãos farináceos procedeu-se à colheita para ensilagem, ocasião em que se determinaram o potencial para ensilagem e composição química e, posteriormente, a qualidade das silagens. Os resultados evidenciaram que a retirada das EPC não afetou (p>0,05) o teor de MS da planta, no estádio de grão leitoso tampouco a composição química no estádio de grãos farináceos. Entretanto, alterou (p0,05) a conservação das silagens. Concluiu-se que o teor de matéria seca constitui o principal fator limitante para ensilagem da fração volumosa da cultura do milho após a retirada das EPC, e que é possível a retirada de até 25% das EPC na forma de milho verde, sem comprometer o valor nutritivo da planta de milho para ensilagem no estádio de grãos farináceos.Editora da Universidade Estadual de Maringá2008-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/323110.4025/actascianimsci.v22i0.3231Acta Scientiarum.
