Resumo: The aim of this work was evaluating the agronomical and chemical characteristics of 20 different genotypes of maize used as silage. A complete randomized experimental design was used, with three replicates per treatment. Each hybrid was harvested when plants reached 1/3 of milk line stage, using two cut heights: immediately above the senescent leaves (whole-plant) and immediately below ear attachment (half-plant), and all hybrids were ensiled in PVC silos. After 50 days of ensiling, DM, CP, EE, ADF, NDF, ash and estimated TDN were determined. DM for all hybrids ranged from 26.56% to 32.19% for whole-plant silage, and from 29.53 to 36.08 for half-plant silage. CP values varied widely among hybrids, ranging from 5.80% to 8.00% in the whole-plant group and from 6.91% to 8.88 in half-plant group. On the basis of DM yield, CP and TDN, one should recommend hybrids GARRA e P30R07 to be used as whole-plant silage in the region under study

O delineamento experimental utilizado foi inteiramente casualizado, com 3 repetições. Os híbridos foram colhidos no estádio ⅓ da linha do leite em duas alturas de corte: imediatamente acima das folhas senescentes (planta inteira) e imediatamente abaixo da inserção da espiga (meia planta), ensilados em silos de PVC por 50 dias. Após abertura dos silos, foram realizadas determinações de MS, PB, EE, FDA, FDN, cinzas e estimativa de NDT. O teor de MS oscilou entre 26,56 e 32,19 e entre 29,53 e 36,08 para planta inteira e meia planta, respectivamente. O teor de PB apresentou alta variação entre os híbridos, sendo os valores obtidos entre 5,80 e 8,00 e entre 6,91 e 8,88 para planta inteira e meia planta, respectivamente. Concluiu-se que, utilizando-se produção de matéria seca/ha, % proteína bruta e % NDT como critérios de seleção, os híbridos mais recomendados para região do leste paranaense são o GARRA e o P 30R07, em se tratando de ensilagem de planta inteiraEditora da Universidade Estadual de Maringá2008-03-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/122010.4025/actascianimsci.v27i2.1220Acta Scientiarum.
