“…For the bromatological composition of silage there was no interaction between silage opening and cultivation systems (P<0.05). The pH showed no difference between the cultivation systems (Table 2), being close to the values considered (Gurgel et al, 2019), indicating that the consortium allows the production of a quality silage (Ribeiro et al, 2017). Cruvinel et al (2017).…”

Maize and forage sorghum crops have a relevant economic importance in Midwest Brazil and there is a need for more information for their intercropping as a strategy for the farmers to reduce inputs. The objective of this work is evaluate if forage sorghum and maize intercropping effects agronomic traits, the bromatological characteristics of silage from the consortium at different times of silo openings, and the economic viability of all crop systems. This experiment was carried on in the field with seven treatments, consisting of monoculture and intercropping of corn and sorghum hybrids. Monoculture of sorghum Agri 001 and maize Agri 320, as well as in maize Agri 320, Agri 340 and Agri 104 intercropped with sorghum Agri 001 had the highest biomass yield. Intercropped maize did not have lodging, reduction in height, nor decrease in the first ear height in relation to the intercropped plants. Maize hybrids intercropped with sorghum led to a better fermentation pattern of silages, reducing ammonia concentrations. However, due the higher contents of NDF and the lower TDN contents of sorghum, nutritional values of intercropped silages were generally smaller than when they were composed only with maize. It was observed that the monoculture of sorghum Agri 001 for silage showed a higher profit compared to the other treatments.

“…The production of silage from tropical grasses has some disadvantages, such as the high moisture content of the plants. Thus, the suitability of the crop for silage involves characteristics such as dry matter (DM) content, soluble carbohydrates (CHO), nitrate and buffering capacity (Gurgel et al ., 2019).…”

The purpose of this study was to evaluate the quality of Marandu grass (Brachiaria brizantha) haylage according to different dry matter (DM) contents in storage. The design adopted was completely randomized with four treatments and five replications. The treatments were DM contents of the plant at the moment of storage (in natura, 30–40, 40–50 and 50–60% DM). The analyses to assess the quality of the haylage were performed after 90 days of storage. The chemical composition, microbiological population, gas quantification, pH, N-NH3, volatile fatty acids, soluble carbohydrates (CHO) and the aerobic stability were evaluated. The means were compared through the Tukey's test and linear regression. The treatment with 50–60% DM presented the highest DM and CHO contents which were 563.8 and 42.0 g/kg, respectively. There was a higher presence of oxygen in the haylage of in natura material, which was 4.8%. There was no difference between treatments for the population of lactic acid bacteria; however, the treatment with 50–60% DM had the highest concentration of enterobacteria. The haylage with 30–40% DM and 50–60% DM presented high concentrations of acetic acid. There was no break in aerobic stability for any treatment within 120 h after opening the bales. There was a smaller amount of N-NH3 in treatments with 40–50% DM and 50–60% DM. The Marandu grass with a DM content of 50–60% for haylage making demonstrated better quality characterization of conserved forage.

“…De modo geral, as gramíneas forrageiras tropicais, como o capim-elefante, no momento em que é possível estabelecer uma boa relação entre produção e valor nutritivo para ensilagem, apresentam alto teor de umidade e o baixo teor de carboidratos solúveis, fatores que inibem o adequado processo fermentativo, impedindo o rápido declínio do pH, permitindo fermentações secundárias indesejáveis e produzindo silagens de baixa qualidade, além de ocasionar perda de nutrientes pela elevada quantidade de efluente produzido (McDonald et al, 1991;Monteiro et al, 2011;Bureenok et al, 2012;Borreani et al;Gurgel et al, 2019).…”

ResumoO capim-elefante (Pennisetum purpureum) tem se destacado como uma opção viável para ensilagem, principalmente, pela sua alta produção de matéria seca e bom valor nutritivo. O objetivo do estudo foi avaliar a composição química e características fermentativas de silagens de capim-cv. BRS Capiaçu enriquecidas com diferentes níveis de inclusão de raízes de mandioca açucarada e amilácea in natura. O delineamento experimental foi o de blocos completos casualizados com cinco repetições. O capim-elefante foi ensilado com diferentes proporções de raízes de mandioca açucarada (RMaç) e amilácea (RMam) com base na matéria natural. Os tratamentos avaliados foram: T1 -Capim-elefante (CE); T2 -CE + 10% RMaç; T3 -CE + 20% RMaç; T4 -CE + 40% RMaç; T5 -CE + 10% RMam; T6 -CE + 20% RMam; e T7 -CE + 40% RMma. Os resultados obtidos, mostram que a inclusão de RMaç e RMam, nos níveis de 20 e 40%, promoveu aumento na digestibilidade in vitro da matéria seca e redução nos teores de lignina e fibra em detergente neutro e ácido. A inclusão de raízes de mandioca açucarada e/ou amilácea em níveis superiores a 20% da matéria verde da massa ensilada melhora o valor nutritivo e mantém adequado padrão de fermentação da silagem de capim-elefante cv. BRS Capiaçu, colhido aos 120 dias de rebrota.
