“…The seasonality of forage production is one of the factors responsible for the low Brazilian livestock productivity rates because sward development is especially accelerated in periods of high rainfall and high temperatures, resulting in a production surplus (OLIVEIRA et al, 2015). Excess forage production is typically underutilized, resulting in delayed grass cutting, compromising both the handling of the grass and the quality of the fodder to be used as livestock feed.…”

The purpose of this study was to evaluate the potential use of fruticulture waste as an additive in elephant grass (Pennisetum purpureum) cultivar Napier silage at different densities, defining the effect of fermentative quality, microbiological characteristics and bromatological composition. The experimental design was completely randomized with four replications in a 4 x 3 factorial scheme, comprising a control, banana waste (BW), mango waste (MW), and passion fruit waste (PFW) at three densities (400, 500 and 600 kg green matter [GM] m -3 ). The effect of ensiling density was greatest in the exclusively elephant grass silage, where a compaction of 600 kg GM m -3 contributed to improvements in fermentation and microbiological processes. The addition of banana waste to the elephant grass silage promoted improvements only in bromatological composition, raising the dry matter (DM), crude protein (CP), and non-fiber carbohydrate (NFC) content and reducing fiber components (neutral detergent fiber [NDFap] and acid detergent fiber [ADFap] corrected for ash and protein), but the addition of banana waste did not favor the fermentative or microbiological processes. The addition of passion fruit and mango by-products promoted increased DM and favored the fermentative, microbiological, and bromatological silage processes, regardless of density. Key words: Additives. Compaction. Fermentation. Microbial. Pennisetum purpureum. ResumoObjetivamos avaliar o potencial de utilização de resíduos da agroindústria de fruticultura como aditivos na ensilagem de capim-elefante (Pennisetum purpureum) cultivar Napier, sob diferentes massas específicas, determinando seu efeito na qualidade fermentativa, características microbiológicas e composição bromatológica. O delineamento experimental utilizado foi inteiramente casualisado com quatro repetições, em esquema fatorial 4 x 3, sendo composto por testemunha, resíduo de banana (RB), resíduo de manga (RMg), resíduo de maracujá (RMj) e três massas específicas (400, 500 e 600 kg matéria verde [MV] m -3 ). O efeito da massa específica no silo é mais efetivo na silagem exclusiva de capim- elefante, onde a compactação de 600 kg MV m -3 contribui para melhorias no processo fermentativo e microbiológico. A adição do resíduo de banana na ensilagem do capim-elefante promoveu melhorias apenas na composição bromotológica, elevando os teores de matéria seca (MS), proteína bruta (PB), carboidratos não fibrosos (CNF) e redução nos componentes fibrosos (fibra em detergente neutro [FDNcp] e fibra em detergente ácido [FDAcp] corrigidos para cinza e proteína), porém não favorece o processo fermentativo e microbiológico. A adição de subprodutos de maracujá e manga promove o aumento da MS e favorece o processo fermentativo, microbiológico e bromatológico da silagem, independente da massa específica. Palavra-chave: Aditivos. Compactação. Fermentação. Microbiológico. Pennisetum purpureum.

“…Os constituintes da parede celular principalmente FDN e FDA estão relacionados com o consumo dos animais, esses são inversamente proporcionais aos CNFs do alimento, e se relaciona com a capacidade do alimento ocupar espaço no rúmen (OLIVEIRA et al, 2015). Os teores de CNFs representam os açucares solúveis em água, sendo considerados os principais substratos para fermentação láctica no interior do silo (ZARDINI et al, 2017).…”

“…Digit grass is a C4 plant (Gusmão Filho, 2018), more commonly grown in Northeastern Brazil, mainly in the states of Sergipe and Alagoas (Souza et al, 2016). This grass is adapted to regions of low mean temperature, low precipitation, and soils with low natural fertility (Navarro et al, 2005), although it appears to be responsive to irrigation (Oliveira et al, 2015) and nitrogen fertilization (Souza et al, 2016). The species presents crude protein content between 10 and 15% (Gusmão Filho, 2018) and 59% total digestible nutrients (Oliveira et al, 2015), indicating its potential for usage in pastures.…”

The objective of this work was to evaluate the tillering dynamics of 'Suvernola' digit grass (Digitaria eriantha) when subjected to different defoliation frequencies. Four defoliation frequencies (interval among harvests) were evaluated -very high, when the grass reached 25 cm in height; high, 35 cm; medium, 45 cm; and low, 55 cm -in two seasons of the year, with higher and lower insolation, A randomized complete block design with four replicates was used. The increase in defoliation frequency increased the number of generations and the appearance, mortality, and density rates of tillers, besides decreasing their survival rate, without changing population stability. At the time of lower insolation, tiller appearance and mortality rates were higher, while tiller survival rate, balance, and density were lower. The evaluated defoliation frequencies and seasons of the year do not change the persistence of digit grass when irrigated. Higher defoliation frequencies result in a greater renewal of digit grass tillers.Index terms: Digitaria eriantha, harvest height, pasture persistence. B.M. de L. Sousa et al.
