“…According to Valeriano et al (2009), the levels of ash in sugar cane are usually low, and the oscillations in gray levels can be used to estimate values of DM loss during fermentation. Teixeira et al (2008) found pH variation of 3.7 to 4.1 for elephant grass silage; and as observed in this study, where the pH was 3.4 to 4.0, the variation and the silage additive with cornmeal presented the best pH, 3.93, when compared to other additives. These data corroborate with what was recommended by McDonald (1981), who states that the pH range great for adequate fermentation lies between 3.6 and 4.2.…”

The objective of this study was to verify the efficiency of different additives on chemical composition, pH, ethanol production, content of volatile fatty acids (VFAs), nutritional losses during fermentation, and changes in fibrous fractions, in the levels of non-fibrous and total carbohydrates during the sugar cane silage fermentation process with different additives. The treatments consisted of control (no additive); corn meal, at 10% of natural matter; molasses, at 10% of natural matter; urea, at 2% of natural matter; and microbial inoculant for sugarcane silage (Lactobacillus plantarum, Kera-Sil®) in a proportion of 2 g L -1 of water using a 2 liter solution per ton of ensilage. The experimental design was a completely randomized design with five treatments and five replications. The urea treatment provided the best preparation of silage, taking into account the pH and bromatological composition when compared to silages made with the other tested additives, and the control. The sugarcane silage showed a loss of 5.86% on average of dry matter, not differing from others additives used. There was an increase in crude protein content when urea was used. There was no difference between the treatment for fiber losses in neutral detergent and total digestible nutrients.

O delineamento experimental utilizado foi o inteiramente casualizado com 5 tratamentos e 5 repetições. O tratamento com ureia proporcionou a confecção da melhor silagem, levando em consideração o pH e composição bromatológica quando comparadas às silagens confeccionadas com os outros aditivos testados e a silagem controle. A cana de açúcar ensilada apresentou perda de matéria seca de 5,86% em média, não diferindo quanto aos aditivos utilizados. Houve acréscimo no teor de proteína bruta quando utilizado o aditivo ureia. Não houve diferença entre os tratamentos para perdas de fibra em detergente neutro e nutrientes digestíveis totais.

“…There was a linear decrease of 1.93 percentage units with increasing levels of Stylosanthes in the silage. These results highlight the importance of the legume in the ensiling of tropical grasses, because the higher the NH 3 -N, the lower the quality of silage, in other words, there is degradation of protein compounds (true protein, peptides, amino acids, amines and amides), by Clostridium bacteria, to ammonia, known as promoters of proteolysis, which is lost by evaporation at the opening of the silo (Teixeira, Veloso, Pires, Silva & Nascimento, 2008). Therefore, the quantification of NH 3 -N values of the silage can be used to determine the efficiency of the fermentation process (McDonald, Henderson & Heron, 1991).…”

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.

“…This reduction resulted from the greater DM concentration and pH values when the brans were added at 32%. The greater DM concentration and pH values reduced the activity of the Clostridium genus bacteria and promoted the proteolysis and the liberation of ammonia during the silage process [15]. In addition, the N-NH 3 /NT concentration is a good indicator for silage quality due to its contribution to the fermentative process [10].…”

The objectives of this study were to evaluate the fermentative and bromatological characteristics of Piata palisadegrass that was ensiled with energetic brans and to assess the costs of different additive levels. This experiment was conducted at the Goiano Federal Institute on the Rio Verde campus in Goiás State, Brazil. The experimental design was entirely random with four replications in a 4 × 5 factorial scheme that included four energetic brans (millet, maize, sorghum and wheat) and five levels (0%, 8%, 16%, 24% and 32%). The energetic brans can be considered as a good source of additives for Piata palisadegrass ensiling, which improves the qualitative and nutritional fermentative characteristics of the silage. The maize and wheat brans were the most efficient for improving the fermentative characteristics of the silage. However, millet bran was the most efficient for improving the bromatological characteristics. In addition, the wheat bran had the greatest influence on the final production cost and the sorghum and millet brans were the most economically feasible. Overall, the addition of 24% bran is recommended due to its beneficial impact on silage quality and the average final production cost of the silage.
