Resumo: | Dry ground corn kernels are widely used as sources of energy readily available for microbial synthesis in the rumen. The objective of the present study was to measure the effect of particle size on the storage length of rehydrated and ensiled corn grain. Commercial corn was milled in 2-, 4-, 6-, 8-, and 10-mm sieves, rehydrated until reaching 65% DM, and ensiled for 14, 28, and 56 days, in a completely randomized design with a 5 x 3 factorial arrangement, with six replications per treatment. PVC mini-silos were used, with dimensions of 25 cm height x 10 cm of diameter. The variables DM, MM, CP, NDF, ADF, pH, molds and yeasts count, fermentative losses, in vitro degradability and aerobic stability were subjected to analysis of variance. The Tukey test was used to compare means. LAB counts was subjected to Wilcoxon's non-parametric test, considering significance at p < 0.05. Rehydrated corn silages with smaller particles (2 and 4 mm) showed higher LAB and mold counts, higher levels of CP and EE and higher density at opening silos than that of coarser particles. However, they showed lower percentages of DM, and were susceptible to microbial attack and faster temperature increases than were coarse particles during the chosen storage times. Silage subjected to 56 days of fermentation showed lower contents of NDF, ADF and CP, lower gas losses and lower pH values in aerobiosis, and increased levels of soluble protein (A + B1 fractions), losses by effluents, number of hours to reach maximum temperature, and time to break aerobic stability. Coarse-grind silages subjected to 56 days of storage showed better chemical composition, lower LAB and mold counts, and less susceptibility to microbial degradation when exposed to air. |

Objetivou-se avaliar o efeito do tamanho de partícula associada ao tempo de armazenamento sobre o milho moído reidratado e ensilado. Foi realizada a moagem de milho comercial em peneiras de 2, 4, 6, 8 e 10 mm, reidratado até atingir 65 % de MS e ensilado por 14, 28 e 56 dias, num delineamento inteiramente casualizado em arranjo fatorial 5x3, com seis repetições por tratamento. Foram utilizados mini-silos de PVC, de dimensões 25 cm altura x 10 cm diâmetro. Os dados referentes às variáveis MS, MM, PB, FDN, FDA, pH, contagem de bolores e leveduras, perdas fermentativas, degradabilidade in vitro e estabilidade aeróbia foram submetidas à análise de variância e o teste Tukey para comparação de médias, e a contagem de BAL foi submetida ao teste não-paramétrico de Wilcoxon, ambos considerando significância 5%. Silagens de grãos milho reidratados com partículas menores (2 e 4 mm) apresentaram maiores contagens de BAL e bolores, teores mais elevados de PB, EE e maior massa específica na abertura dos silos em relação às partículas mais grossas. Porém, demonstraram menores percentuais de MS, e foram passíveis de ataque microbiano e elevação de temperatura mais rapidamente do que partículas grossas durante os tempos de armazenamento avaliados. Silagens armazenadas por 56 dias apresentaram menores teores de FDN, FDA e PB, menores perdas por gases e menores valores de pH em aerobiose, e aumentaram a proteína solúvel (frações A + B1), as perdas por efluentes e o tempo para quebra da estabilidade aeróbia das silagens. Silagens com moagem grossa e submetidas a 56 dias de armazenamento apresentaram melhor composição bromatológica, menores contagens de BAL e bolores, e menor susceptibilidade à degradação microbiana quando expostas ao ar.UEL2021-03-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionartigo científicoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3995810.5433/1679-0359.2021v42n3p1189Semina: Ciências Agrárias; Vol. 42 No. 3 (2021); 1189-1208Semina: Ciências Agrárias; v. 42 n. 3 (2021); 1189-12081679-03591676-546Xreponame:Semina.
