“…The mean productive parameters of the crops are shown in Table 1. The dry matter yield (DMY) of corn was, on average, 13,500 kg ha -1 , a value similar to those found by Buso, Machado, Ribeiro and Silva (2018) in tests of five corn hybrids in monoculture for silage. For marandu palisadegrass, yields of 208.25 and 523.13 kg ha -1 were found at the 1/4 milk line and maturity stages, respectively, and these yields were significantly different (P <0.05).…”

“…The chemical composition of the silages is shown in Table 4. The average CP content was 7.24% DM, which is close to that found by Buso et al (2018) in a study evaluating corn hybrids for silage. There was a significant difference between CP levels in the different cutting height treatments; this is different from what was observed by Marquardt, Jobim, Bueno and Ribeiro (2017), who, when working with silage corn harvested at 20 and 40 cm above the ground, did not observe any difference between the levels of CP; however, none of these treatments came from intercropping systems with forages.…”

The objective of this study was to evaluate the yield and nutritional value of silage made from corn intercropped with marandu palisadegrass (Urochloa brizantha cv. Marandu) in an integrated crop-livestock system. The corn was harvested at different maturity stages and cutting heights and was processed or not before ensiling. The experimental design was a randomized block with four replications in a 2x2x2+1 factorial scheme. The treatments were composed of silage corn intercropped with marandu palisadegrass harvested at two cutting heights (20 or 45 cm) and two stages of maturity (1/4 of the kernel milk line or kernel physiological maturity) and subjected to two methods of processing (crushing or not crushing). A control treatment composed of conventionally grown corn silage was also included. The total dry matter yields of both crops did not differ significantly among treatments, demonstrating the viability of the intercropping system for both forage species. Although the dry matter content of the corn plants was higher at the time of ensiling, the fermentative and nutritive quality of the silages was not affected. Increasing the cutting height increased the grain content of the forage mass and also avoided harming the development of the intercropped grass. The silages from the physiological maturity treatment and from the processed treatment had the best quality.

“…The behavior of fiber components of the whole plant (Table 3) is due to the increase in grain participation (Table 2). According to Buso, Machado, Ribeiro and Silva (2018), the higher grain participation provides increase in starch concentrations, causing dilutions in the NDF content of plants at advanced maturity stages.…”

“…Marafon et al (2015) attributed the increase in RFV at advanced maturity stages to higher concentration of grains. Buso et al (2018) used the same argument to explain the increase in non-fiber carbohydrate concentration at these stages; according to these authors, grain is a starch-rich and lowfiber component. Table 3 also indicate that the plant without grains gradually lost its quality with the advance of maturity stages, which is a consequence of the thickening and lignification of the cell wall (Velásquez et al, 2010).…”

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 grau de estabilização é obtido com maior rapidez nos silos experimentais que nos comerciais, já que as condições para que ocorra o processo de fermentação anaeróbica se dá em menor tempo alterando os resultados. No Brasil, foram realizados poucos experimentos (PEDROSO et al, 2014;BUENO et al, 2020;MARTIN et al, 2012;TAVARES et al, 2009;TAVARES et al, 2019;OLIVEIRA et al, 2011;BUSO et al, 2018;CRUZ et al, 2019;NEUMANN et al, 2007;OLIVEIRA et al, 2013;MOMBACH et al, 2019) buscando estudar os microssilos experimentais utilizados para avaliação da silagem que se aproxime das condições de campo.…”

Objetivou-se, com o presente estudo, testar diferentes tipos, formas e volumes de silos experimentais na produção de silagem de milho e sorgo, para as principais características bromatológicas, matéria seca e concentração de nutrientes no tecido ensilado. O experimento foi conduzido na área experimental da Universidade Tecnológica Federal do Paraná, no Campus Dois Vizinhos no período entre dezembro de 2008 a junho de 2009. Os silos experimentais testados em ambas as culturas foram: baldes plásticos rígidos, com capacidade para 3 L e 15 L; canos de PVC de diferentes comprimentos e diâmetros, contendo ou não uma base com areia para armazenamento de efluentes; sacolas de plástico flexível com capacidade para 5 kg e 10 kg; e garrafas PET, com capacidade para 2 L. As características avaliadas foram: matéria seca, proteína bruta, fibra em detergente neutro, fibra em detergente ácida, extrato etéreo, matéria mineral, energia líquida de lactação, nutrientes digestíveis totais, teores de nitrogênio, fósforo, potássio, cálcio e magnésio no tecido vegetal. Também foram estimados os valores de ingestão de matéria seca, energia líquida de lactação e nutrientes digestíveis totais. Como resultados, verificou-se que o tipo de microssilo experimental não interfere nas características bromatológicas e teores de nutrientes, apenas o teor de matéria seca foi diferente entre os microssilos, para as culturas do milho e sorgo.
