“…Nevertheless, the increase in grain participation obtained in the present study and reported by other authors is considered by Mendes, Gabriel, Faria, Rossi and Possatto (2015) as desirable, since they give higher energy value to the silage produced (Marafon et al, 2015), but it is noteworthy that one should not only consider this parameter to characterize the harvesting time as appropriate or not for silage production. Table 3 lists the chemical composition of the whole plant and the grain-free plant harvested at different maturity stages.…”

“…For the whole plant RFV, higher values were obtained at R4, R5 and R6 stages, which did not differ (P> 0.05), whereas the grain-free plant presented a decreasing linear behavior with advancing 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.…”

“…According to Oliveira et al (2013) and Marafon et al (2015), corn plants destined for silage production should be harvested in more advanced maturity stages; in this way its potential for production of dry biomass and grains is exploited to the maximum. Semina: Ciênc.…”

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.

“…Ensiled crops, before the ideal point, besides presenting lower total mass production, have a higher NDF content due to the occurrence of effluent and the lower share of the grain fraction in the mass ( VAN SOEST, 1994;VILELA et al 2008). Similarly, Marafon et al (2015), evaluating different maize harvesting stages, observed that maize plants in the R5 stage presented lower FDN and FDA content, when compared to the R3 stage due to the dilution of these fractions, by the transformation of simple sugars into starch in the grain component. Also, VAN SOEST et al, (1991), points out that good silage must comply with some minimum quality criteria.…”

“…Still, there is a large number of maize hybrids destined for silage production, from which significant differences with respect to the production of Green forester, production of grains, leaves and stalk directly interfering with the nutritional value of the silage (MORAES et al, 2013). In this sense, the choice of hybrid and reproductive stage of cutting becomes determinant factors for the success of the system, since the hybrid may represent up to 50% of the final yield (FACTORI et al, 2012), and the stage of cutting that the plant is in, is directly related to the available energy of this material, by increasing the participation of grains (MARAFON et al, 2015). In this context, it is important studies, which demonstrate the best strategy for harvesting these hybrids, which provide higher milk production ha-1 and economic income for the rural producer.…”

Corn has been the most used crop for whole plant silage, due to its high potential for dry matter production, high energy and great adaptability to different growing regions. Due to the great importance of the culture for this purpose, the region of the Far West of Santa Catarina, due to the presence of one of the largest dairy basins in Brazil, demands the supply of this food to the animals mainly during the season of forage. Thus, the objective of this work was to evaluate different hybrids and to identify the optimal corn cutting time for silage production that provides a greater economic return to the system. The experimental design used was a randomized complete block design in a 2x4 factorial scheme, allocating different maize hybrids (P30F53 VYHR®; P32R48 VYHR®) to the main plot and the reproductive stages (R2, R3, R4, R5). The experiment had 8 treatments and 3 replicates, totaling 24 experimental units. The studied variables were: dry matter content (DM); crude protein (PB); acid detergent insoluble fiber (FDA); neutral detergent insoluble fiber (NDF); total digestible nutrients (NDT), and CNF-amido, at the reproductive stages. The best economic yield is obtained when the maize crop is ensiled at the reproductive stage R4 and R5. Among the hybrids, the P32R48 VYHR® was the one that obtained better yield, providing greater production of milk by área.

A silagem de milho é um dos alimentos conservados mais utilizados na produção animal durante a seca. Objetivou-se avaliar a composição química da silagem de milho com diferentes aditivos. O delineamento foi casualizado, em esquema fatorial 3x3 (três valores de adição do coproduto farelo úmido de glúten de milho e dois aditivos + um sem aditivo), com três repetições, totalizando 27 unidades experimentais. Foi utilizada análise de variância com 5% de significância e teste de Scott-Knott para os dados obtidos. Os valores de nutrientes digestíveis totais e de matéria seca aumentaram proporcionalmente às inclusões do coproduto nas silagens com aditivos. As variáveis proteína bruta e fibra em detergente neutro apresentaram o mesmo comportamento, enquanto os valores de fibra em detergente ácido sofreram redução nas silagens com 30% do coproduto. Silagens tratadas com benzoato apresentaram maiores teores de cinzas. Menores valores para o teor de extrato etéreo foram encontrados nas silagens sem inclusão do coproduto. O uso de 15 e 30% de farelo úmido de glúten de milho não teve efeito sobre a composição química da silagem.Palavras-chave: coproduto, farelo úmido de glúten de milho, produção animal Chemical composition of corn silage with additivesABSTRACT. Corn silage is one of the most conserved feed used in animal production during drought. The objective of this study was to evaluate the chemical composition of corn silage with different additives. The design was randomized, in a 3x3 factorial scheme (three values of the addition of wet corn gluten feed and two additives + one without additive), with three replications, totaling 27 experimental units. We used analysis of variance with 5% significance and Scott-Knott's test for the data obtained. The values of total digestible nutrients and dry matter increased proportionally to the co-product inclusions in the silages with additives. The crude protein and neutral detergent fiber presented the same behavior, while the values of acid detergent fiber were reduced in the silages with 30% of the co-product. Silages treated with benzoate showed higher ash content. Lower values for ethereal extract content were found in the silages without inclusion of the co-product. The use of 15 and 30% of wet corn gluten feed had no effect on the chemical composition of the silage.
