Silage quality of Piata palisadegrass with palm kernel cake

ABSTRACT. The seasonality of forage production represents a limiting factor in the production of ruminants. The use of silages has been a solution for periods of low forage production, providing high quality food. This study was conducted to evaluate the fermentative characteristics and the chemical composition of silage of Urochloa brizantha cultivars with different levels of Campo Grande Stylosanthes. It was used a complete randomized block design with three replications in a 2 x 4 factorial design, being two cultivars of Urochloa brizantha (BRS Piata palisadegrass and BRS Paiaguas palisadegrass) and four levels of Campo Grande Stylosanthes (0, 10, 20 and 30%). Silages of Urochloa brizantha with Campo Grande Stylosanthes exhibit satisfactory quality, on the basis of the characteristics evaluated, with no significant difference between cultivars. The mixed silage of Campo Grande Stylosanthes with grasses at 30% has proven to be an interesting option, thus promoting adequate fermentation and maintaining the nutritional quality of silage. Keywords: chemical composition, fermentation, inoculant.Qualidade da silagem de cultivares de Urochloa brizantha com níveis de Estilosantes campo grande RESUMO. A estacionalidade da produção de forragem é um dos fatores limitantes na produção de ruminantes. Sendo assim, a utilização de silagens tem sido uma solução para períodos de baixa produção de forragens, proporcionando alimento de boa qualidade. Com isso, desenvolveu-se esse estudo com o objetivo de avaliar as características fermentativas e a composição químico-bromatológica da silagem de cultivares de Urochloa brizantha com níveis de estilosantes Campo Grande. O delineamento experimental utilizado foi o de blocos completos ao acaso, com três repetições, em esquema fatorial 2 x 4, sendo dois cultivares de Urochloa brizantha (BRS Piatã e BRS Paiaguás) e quatro níveis de estilosantes Campo Grande (0, 10, 20 e 30%). Os resultados demonstraram que as silagens de Urochloa brizantha (BRS Piatã e BRS Paiaguás) com o estilosantes Campo Grande apresentam qualidades aceitáveis, com base nas características avaliadas, não havendo diferença entre os cultivares. A silagem mista de estilosantes Campo Grande com gramíneas na proporção de 30% demonstrou ser uma opção interessante, favorecendo o adequado processo fermentativo, bem como garantindo a manutenção da qualidade nutricional da silagem.Palavras-chave: composição químico-bromatológica, fermentação, inoculante.

“…The greatest lignin concentration in silages of monocropped Paiaguas palisadegrass (Table 6) is probably due to the greater fiber fractions of the grass. Figueredo et al (2014) observed lignin concentrations of 49.12 g kg −1 in silages of Piata palisadegrass in the exclusive form, but in the present study, values were above this level, with a mean value of 69.54 g kg −1 . Thus, these great concentration may limit the digestion of some tissues, not only by the negative effect of lignin on the digestion of cell wall components, but also by the arrangement of cells and by the large cell wall thickness (Oliveira et al, 2010).…”

The objective of this study was to evaluate dry matter production, fermentative parameters, and nutritional value of the silage of corn intercropped with Paiaguas palisadegrass in different forage systems and maturity stages, in the off-season. The experiment was carried out in a randomized block design, with four replications, in a 5×3 factorial arrangement consisting of five forage systems: corn monocropped; Paiaguas palisadegrass monocropped; corn intercropped with Paiaguas palisadegrass in the row, inter-row, and oversown; and three corn maturity stages (milky, soft dough, and hard dough with 80, 90, and 110 days after sowing, respectively). The results showed that the silage of corn intercropped with Paiaguas palisadegrass in the row and inter-row at the hard dough stage presented greater productivity per area and better fermentative and nutritional characteristics. They can, therefore, be recommended as suitable sowing systems for silage production. Silages produced from intercropping systems proved to be an alternative feed supply technique, allowing the intensification of production systems, maximizing nutrient production per area, in a sustainable manner.

In this sense, the adsorbent additives, characterized by reducing or eliminating effluent production, may assume relevance in the production of forage grass silages with high moisture content.…”

ABSTRACT. The aim of this study was to evaluate the fermentative losses and nutritional value of elephant grass silages with the increasing of inclusion levels of dehydrated banana peel. The experiment was conducted in a completely randomized design, with six treatments and four replications, being the silage exclusively from elephant grass, and five levels of inclusion of banana peel to the elephant grass silage, as the following -5; 10; 15; 20 and 25%, being added based on natural matter. The addition of the banana peel in the silage reduced linearly (p < 0.05) the pH, the ammoniacal nitrogen and the losses of the fermentative process. In addition, the inclusion of banana peel increased linearly (p < 0.05) the dry matter and non-fibrous carbohydrates. On the other hand, the neutral detergent fiber and the acid detergent fiber were linearly reduced with the inclusion of the banana peel (p < 0.05), but there was no change in the dry matter digestibility in situ. The inclusion of dehydrated banana peel in elephant grass silage reduces the losses of the fermentation process with more consistent results at the 25% inclusion level, however, it reduces the silage nutritional value due to fibrous and protein quality.Keywords: co-product, fermentation, Musa, Pennisetum purpureum.Características fermentativas e valor nutricional da silagem de capim-elefante aditivada com casca de banana desidratada RESUMO. Objetivou-se com este estudo avaliar as perdas fermentativas e o valor nutricional das silagens de capim-elefante com níveis crescentes de inclusão da casca de banana desidratada. O experimento foi conduzido em delineamento inteiramente casualizado, com seis tratamentos e quatro repetições, sendo silagem exclusiva de capim-elefante e cinco níveis de inclusão da casca de banana à silagem de capimelefante -5; 10; 15; 20 e 25%, sendo adicionada com base na matéria natural. A adição da casca de banana na ensilagem reduziu linearmente (p < 0,05) o pH, nitrogênio amoniacal e as perdas do processo fermentativo. Ademais, a inclusão da casca de banana aumentou de forma linear (p < 0,05) a matéria seca e os carboidratos não fibrosos. Já a fibra em detergente neutro e em detergente ácido reduziu linearmente com inclusão da casca de banana (p < 0,05), mas não houve alteração na digestibilidade in situ da matéria seca. A inclusão de casca de banana desidratada na ensilagem do capim-elefante reduz as perdas do processo fermentativo com resultados mais consistentes no nível de 25% de inclusão, entretanto, reduz o valor nutricional por detrimento da qualidade fibrosa e proteica.
