“…[11] explained that proteolysis is extended during fermentation when acidic conditions are not sufficient for inhibiting undesirable microorganisms. Similar results were obtained by [18], who evaluated elephant grass silage and observed that low CP concentrations occurred in silage without additives due to the loss of soluble nitrogenated compounds in the effluent. However, at the 8%, 16%, 24% and 32% levels, the lowest concentrations were obtained from the maize and sorghum brans (P < 0.05), which differed from the millet and wheat brans.…”

“…At the 24% and 32% levels, the N-NH 3 /NT concentrations for all of the brans were between 2.87% and 2.02%. These results were greater than the results that were obtained by [18], in which elephant grass silage was evaluated. These authors identified average N-NH 3 /NT concentrations of 3.95% following the addition of rice bran, soybean hulls, maize flour and sugar cane.…”

“…In addition, at the 24% and 32% levels, the maize and sorghum brans resulted in greater soluble CHO concentrations relative to the millet and wheat brans. [18] evaluated elephant grass silage with alternative products and verified that additions of rice bran, soybean hulls, maize flour and sugar cane resulted in average concentrations of 15.96%. These values were greater than the values that were obtained here.…”

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.

“…This is due the lower cost per ton of DM obtained with these silages, corroborating the economic results obtained in the present work. In view of the greater competitiveness of livestock farming in relation to agriculture through land use, and aiming at better remuneration over invested capital, we have sought complementary production technologies that provide integrated benefits to the production system as a whole (Monteiro, Abreu, Cabral, Ribeiro, & Reis, 2011). Thus, as suggested by Vieira et al (2010), the agronomic management of crop to obtain satisfactory nutritive value and with high-yielding pastures would justify the use of this forage as a preserved food, allied to the process of intensification of meat and milk production in pastures.…”

ABSTRACT. The objective of this study was to evaluate the viability of pasture with high production capacity and the potential for production of silage using different sources and doses of nitrogen (N) by quantifying the productivity of dry matter (DM), some qualitative characteristics, the total cost of production (TC) and total operating cost (TOC) of silage production. The experimental design was randomized block in a factorial scheme with four replications including two sources of nitrogen (urea and ammonium nitrate) and five N doses (0, 50, 100, 150, and 200 kg ha -1 by cutting). The increase in N provided greater DM and crude protein content and reduced the fiber content in neutral detergent. The source of N did not affect the chemical composition, and therefore, it is recommended to use urea due to the ease of acquisition and higher economic return. The production of Mombasa silage can be economically viable due to high DM and crude protein content combined with low production costs. The smallest TC and TOC were obtained in the absence of nitrogen fertilization; however, the proper management of N ensures high productivity in cattle feed with higher total profit when using 100 kg ha Viabilidade técnica, econômica e qualidade nutricional da produção de silagem de capimmombaça RESUMO. Objetivou-se estudar a viabilidade de uma pastagem com alta capacidade produtiva e o potencial para produção de silagem de capim, utilizando fontes e doses de nitrogênio (N), quantificando-se a produtividade de matéria seca (PMS), algumas características bromatológicas, o custo total de produção (CT) e o custo operacional total (COT) da produção de silagem. O delineamento experimental foi em blocos casualizados, adotando um esquema fatorial com quatro repetições, sendo duas fontes de nitrogênio: ureia, e nitrato de amônio, e cinco doses de N (0, 50, 100, 150 e 200 kg ha -1 por corte). O incremento de N propiciou maior PMS e teor de proteína bruta, além de diminuir os teores de fibra em detergente neutro. As fontes de N, não influenciaram na composição química, e desta forma recomenda-se utilizar a ureia em função da facilidade de aquisição e maior retorno econômico. A produção de silagem de capim-Mombaça pode ser economicamente viável em função da elevada PMS e proteína bruta, aliado ao baixo custo de produção. O menor CT e COT foi obtido na ausência da adubação nitrogenada, entretanto, o manejo adequado de N garante boa produtividade e rendimento na alimentação do rebanho, com maior lucro total obtido na utilização de 100 kg ha

“…O uso do milho moído tem sido descrito como um aditivo importante na melhora da qualidade fermentativa e bromatológica de silagem de capim-elefante e também em outras forrageiras (Andrade et al, 1998;Monteiro et al, 2011). Seu uso é justificado principalmente para suprir alguma deficiência característica da forrageira ensilada.…”

este estudo testar o aumento linear da inclusão de glicerina bruta (86% de pureza) em substituição ao milho moído, como aditivo, na forragem de capim-elefante destinada a ensilagem, avaliando-se a qualidade nutricional do alimento e a viabilidade da ensilagem do material. Foram testados cinco níveis de substituição do milho pela glicerina em taxas que variaram de 3,12 a 12,5% sobre a matéria natural da forragem, além de um tratamento controle (apenas forragem). Realizaram-se análises bromatológicas e de digestibilidade para avaliar o valor nutricional da mistura durante a ensilagem e após o processo fermentativo, na silagem. Para avaliar a qualidade fermentativa foram feitas avaliações de pH, nitrogênio amoniacal, recuperação de matéria seca e densidade. A inclusão do milho moído incrementou (P<0,05) o teor de matéria seca em até 28%, tanto na forragem fresca, bem como na silagem. Tanto a inclusão do milho, bem como a substituição deste pela glicerina resultou (P<0,05) em um incremento médio de 25% e 32% na digestibilidade in situ e valor energético da silagem, respectivamente quando comparado ao capim puro. Isto, devido ao decréscimo (P<0,05) dos teores de fibra em detergente neutro e fibra em detergente ácido na silagem. A inclusão de glicerina aumentou (P<0,05) as perdas de proteína bruta durante a fermentação e diminuiu a recuperação da matéria seca. O teor de matéria seca da forragem parece ser fator chave para o sucesso de inclusão da glicerina como aditivo na ensilagem do capim-elefante, no intuito de evitar perdas expressivas de qualidade nutricional durante a fermentação.Palavras-chave: avaliação nutricional, fermentação, subproduto. REPLACEMENT OF GROUND CORN WITH GLYCERIN IN ELEPHANT GRASS SILAGEABSTRACT: This study was performed to test the linear inclusion of crude glycerin (86% purity) replacing ground corn as an additive mixed with elephant grass forage for silage, evaluating the nutritional quality of the food and the viability of silage. Five levels of glycerin as corn substitute were tested, ranging from 3.12 to 12.5% of total forage green matter, in addition to a control treatment (forage only). Bromatological and digestibility analyses were carried out to evaluate the nutritional value of the mixture during ensiling and of the silage after the fermentation process. The pH, ammoniacal nitrogen, dry matter recovery, and density were measured to evaluate the fermentative quality. The inclusion of ground corn increased (P<0.05) by 28% the dry matter content in both fresh forage and silage. The inclusion of corn and its substitution with glycerin improved (P<0.05) by 25 and 32% in in situ digestibility and the energy value of the food, respectively, when compared to the control treatment. This finding was due to a decrease (P<0.05) in neutral detergent fiber and acid detergent fiber in silage. The inclusion of glycerin increased (P<0.05) crude protein losses during fermentation and decreased dry matter recovery. The dry matter content of forage seems to be a key factor for the successful inclusion ...
