Resumo: | The goal of the present study was to evaluate the biomass and grain yield, the morphological and chemical composition, production costs and the ruminal disappearance of the whole corn plant and grain-free corn plant harvested at different reproductive stages. The experimental design was completely randomized, consisting of six treatments, where each treatment corresponded to a stage of corn maturity. The advance of plant cycle promoted an increase in dry biomass and grain yields per unit area, reducing production costs. Higher participation of grains and lower participation of structural components promoted a reduction in NDF and ADF, with the lowest values in dough grain (R4) and dent grain (R5) stages. The advancement of stages promoted an increase in production and a reduction in costs, but significantly reduced the quality of grain-free plants, increasing the NDF, ADF and ADL; but R4 and R5 presented NDFd of 84.80 % and 82.79 %, respectively, showing to be a good quality fiber. R4 stage had the highest rumen disappearance values after 24 and 48 hours of incubation. Based on chemical data, ruminal disappearance, ruminal degradation kinetics of the whole corn plant and without grains, the R4 stage of the evaluated hybrid is the stage at which the plant had the best quality, representing the appropriate stage to harvest the material for making silage, aiming at the production of a silage with good chemical quality. |

O delineamento experimental foi inteiramente casualizado, composto por seis tratamentos, onde cada tratamento correspondeu a um estádio de maturação do milho. A evolução do ciclo das plantas promoveu aumento na produção de biomassa seca e de grãos por unidade de área, proporcionando redução nos custos de produção. A maior participação de grãos e a menor de componentes estruturais promoveu redução nos teores de FDN e FDA, tendo os menores valores nos estádios de grão farináceo (R4) e grão duro (R5). O avanço dos estádios promoveu aumento na produção e redução nos custos, porém reduziu significativamente a qualidade da planta sem grãos, elevando os teores de FDN, FDA e LDA, porém R4 e R5 obtiveram FDNd de 84,80 % e 82,79 % respectivamente, mostrando ainda ser uma fibra de boa qualidade, o estádio R4 possuiu os maiores valores de desaparecimento ruminal em 24 e 48 horas de incubação. Embasado nos dados bromatológicos, nos custos de produção, desaparecimento ruminal, cinética da degradação ruminal da planta de milho inteira e sem grãos o estádio R4 do híbrido avaliado é o estádio em que a planta possuiu melhor qualidade, sendo este o momento adequado para realizar a colheita do material para confecção de silagem, visando a produção de uma silagem com boa qualidade bromatológica.UEL2021-01-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Cientificaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3955410.5433/1679-0359.2021v42n1p283Semina: Ciências Agrárias; Vol. 42 No. 1 (2021); 283-300Semina: Ciências Agrárias; v. 42 n. 1 (2021); 283-3001679-03591676-546Xreponame:Semina.
