“…Além da pré-secagem, os produtores podem utilizar aditivos sequestrantes de umidade com o intuito de se elevar a matéria seca da massa ensilada. O milho desintegrado com palha e sabugo, polpa cítrica, raspa de batata e mandioca, farelo de trigo, grão de milho moído, rolão de milho (Perim et al, 2014;Rezende et al, 2008), glicerina (Tonin et al, 2018), além de muitos outros subprodutos como casca de café, bagaço de laranja in natura, restos da cultura da soja (Barcelos et al, 2018;Dias et al, 2014;Ítavo et al, 2000;Lopes et al, 2007;Siqueira, 2009) são aditivos que elevam os teores de matéria seca.…”

Resumo. O Brasil possui diversas espécies de capins tropicais que podem ser ensiladas. Esses capins apresentam alto potencial de produção de forragem. Todavia, a maior produção dessas gramíneas ocorre nos períodos de maior disponibilidade de fatores abióticos, o que promove à estacionalidade na produção forrageira, sendo necessário o uso de tecnologias de conservação de forragens para manter alimentos de maior qualidade em tempos de escassez. A ensilagem de capins tropicais no Brasil tem sido limitada por fatores operacionais e por questões inerentes à própria planta, pois, invariavelmente essas plantas apresentam baixos teores de matéria seca e de carboidratos solúveis, além de uma alta capacidade tamponante no momento ideal do corte. Para contornar esses problemas, temse utilizado alguns aditivos com resultados bem interessantes; porém, esta prática pode onerar ainda mais o processo produtivo. Portanto, pretende-se com esta revisão, discutir os principais entraves da produção de silagens a partir de capins tropicais, os fatores que podem alterar a qualidade da silagem e as implicações ao inserir esse tipo de volumoso na dieta de ruminantes.

“…O uso da silagem de gramíneas forrageiras tropicais tem se tornado uma prática cada vez mais comum na alimentação de ruminantes (Epifanio et al, 2014;Perim et al, 2014;Rêgo et al, 2010). No entanto, essas plantas apresentam características que podem influenciar a qualidade da silagem.…”

“…Since carbohydrate fractions are based on their rate of degradation (Du et al, 2020), their study in high-inclusion feeds, such as silages, is essential. This is because the A+B1 fraction is soluble and offers rapid ruminal degradation (Sniffen et al, 1992); it is the main source of energy for ruminal microorganisms that use non-fibrous carbohydrates (Perim et al, 2014). Fraction A is rapidly fermented in the rumen by bacteria and is composed mainly of water-soluble sugars, organic acids, and short chain oligosaccharides (Du et al, 2020), whereas fraction B1 indicates soluble fibre, starch, and pectin and has a slower digestion rate than fraction A (Du et al, 2020).…”

“…The B2 fraction was higher in Maxisilo silages (447 g/kg) and lower in Qualysilo silage (329 g/kg) while Chopper (409 g/kg) and Dominator (370 g/kg) silages were similar (data presented only in the text). This fraction provides energy slowly in the rumen and can affect the efficiency of microbial synthesis and animal performance (Perim et al, 2014) when present in high proportions in the diets. The main components of fraction B2 are cell wall degradable carbohydrates, which, despite a slow rate of digestion (Du et al, 2020), are considered as potentially digestible fibre fractions in the rumen (Brandstetter et al, 2019).…”

The objective of this study was to evaluate the nutritional changes in silages of four sorghum hybrids at different storage times. The design was a completely randomized in a 4 × 9 arrangement of plots with four replications. The four sorghum hybrids, Qualysilo, Chopper, Dominator, and Maxisilo, were allocated to the plots. In the subplots, sampling times were considered in fresh material and after 1, 3, 7, 14, 28, 56, 112, and 224 days of storage. The material was ensiled in experimental polyvinyl chloride silos and subsequently evaluated for chemical composition and fermentative profile over the nine different periods of the fermentation process. Crude protein was reduced by 1.21g/kg per day until the third day of fermentation. The levels of neutral detergent insoluble nitrogen and acid detergent insoluble nitrogen exceeded the upper limit of 311 g/kg of N. Of the studied silages, an NDF content of 734 g/kg was obtained in Maxisilo, which was higher than the other silages (average: 547 g/kg). Silage production can be achieved with the four materials; however, the Maxisilo sorghum provides silages of lower quality, with a DM content of less than 30%. The other materials fit into the nutritional profiles proposed by the literature, characterizing them as good quality silages.

“…Figure 3c shows a linear increase in protein fraction B2 with the addition of Tamani guinea grass, with a maximum increase of 16.67% compared to that in corn only silage. This result is relevant for improving the quality of corn silage; despite its high energy content (Perim et al, 2014b), corn silage has lower protein content (Table 1) when compared with Tamani guinea grass. Fraction B2 has a moderate ruminal degradation rate, but fractions B1 + B2 are characterized by faster rumen degradation rates than fraction B3, thus contributing to microbial nitrogen supply (Sniffen et al, 1992).…”

The use of silage has been an efficient alternative to feed supply during the shortage of roughage in dry periods, providing quality feed that is widely used in ruminant feeding. Thus, the objective of this study was to evaluate the fermentative characteristics and nutritive value of corn silage with Tamani guinea grass (Panicum maximum BRS cv. Tamani) through chemical composition, in vitro dry matter digestibility and protein fractionation. The experiment was conducted in a completely randomized design with four replications. The treatments consisted of five silages: corn; corn with 10% Tamani guinea grass; corn with 20% Tamani guinea grass; corn with 30% Tamani guinea grass; and corn with 40% Tamani guinea grass, totalling 20 experimental silos. The addition of tamani grass to silages was determined based on fresh matter. For ensiling, corn was harvested with 320 g kg-1 DM (dry matter) and Tamani guinea grass in a 30-day development cycle with 286 g kg-1 DM. After 50 days of silage, the silos were opened to analyse the fermentative characteristics, chemical composition and protein fractionation of the silage. The results showed that the addition of Tamani guinea grass in corn silage increased the pH and buffering capacity and reduced the dry matter and lactic acid concentration but did not compromise the fermentative characteristics of silages. The addition of 40% Tamani guinea grass in corn silage provided increased levels of crude protein, in vitro dry matter digestibility, protein A, B1 and C, and decreased the fractions B3 and C, which makes Tamani guinea grass an alternative to improve the quality of exclusive corn silage, resulting in better quality silage.
