“…Therefore, the high moisture at the ideal time for harvesting, the low content of soluble carbohydrates, and the high buffering capacity of this grass, inhibit an suitable fermentation process, hampering the production of a good quality silage (McDONALD;HENDERSON;HERON, 1991). These factors negatively influence the fermentation process, hindering the rapid decrease in pH, allowing an undesirable secondary fermentation (EVANGELISTA et al, 2004).…”

The goal of this study was to evaluate the fermentative and bromatological characteristics of Piata palisadegrass (Brachiaria brizantha cv. Piata) ensiled with levels of meals from biodiesel industry. The experiment was performed at the Federal Institute of Goias State, Campus Rio Verde. The experiment was a completely randomized design with four replications, in 4 x 4 factorial arrangement, being four meals (cotton, sunflower, soybean, and canola) and four levels of inclusion (0, 5, 10 and 15%). The results showed the oleaginous meals from biodiesel industry are indicated as additives for ensiling Piata palisadegrass, by improving the qualitative, nutritional and fermentative characteristics of the Piata palisadegrass silage. It is recommended the addition of 15% of the meals, since this level provides the best quality of silage. The soybean meal is the most effective to improve the silage quality, in comparison with the other additives. Key words: Additive, Brachiaria brizantha, crude protein, fibrous materials ResumoDesenvolveu esse estudo com o objetivo de avaliar as características fermentativas e bromatológicas do capim-piatã ensilado com níveis de farelos da indústria do biodiesel. O experimento foi conduzido no Instituto Federal Goiano, Campus Rio Verde. O delineamento experimental utilizado foi o inteiramente casualizado, com quatro repetições, em esquema fatorial 4 x 4, sendo quatro farelos (algodão, girassol, soja e canola) e quatros níveis de adição (0, 5, 10 e 15%). Os resultados demonstraram que os farelos da indústria do biodiesel pode ser indicado como aditivos para a ensilagem, por trazer melhorias nas características fermentativas, qualitativas e nutricionais da silagem de capim-piatã. Recomenda-se a adição do nível de 15% dos farelos, por proporcionar melhor qualidade da silagem. O farelo de soja mostrou-se mais eficiente para melhorar a qualidade da silagem, quando comparados com os outros aditivos.

“…However, high humidity and low carbohydrate levels at the cutting time of tropical grasses are factors that inhibit the proper fermentation process, preventing the production of good quality silage. These factors negatively affect the fermentation process, preventing the rapid pH decrease to proper levels and thus allowing undesirable secondary fermentations (Evangelista et al, 2004).…”

The silage quality of Brachiaria brizantha cultivars ensiled with different levels of millet meal was evaluated. The experimental design was a completely randomized with three replications in a factorial 3 x 4, with three cultivars of Brachiaria brizantha: marandu, xaraés, and piatã and four levels of millet meal 0, 5, 10, and 15%. The addition of millet meal improved the quality of B. brizantha silage. The inclusion of the additive at 15% provided the best nutritional values. The piatã silage had the lowest contents of neutral detergent fiber, acid detergent fiber, and lignin and the highest content of total digestible nutrients, being a better quality silage as compared to those of xaraés and marandu grasses.

“…Elephant grass is characterized by low dry matter content (DM), high buffering power and low water soluble carbohydrate contents at the young stage of maturity, characteristic of secondary fermentations during ensilage (Evangelista et al, 2004). However, it presents fast physiological maturity and short delays in cutting cause modifications in the chemical composition that harms forage digestibility in the rumen (Deschamps, 1999) that justifies ensilage with the use of additives.…”

-The effects of different ratios of sugarcane and elephant grass (0:100, 25:75, 50:50, 75:25 and 100:0% of the natural basis) were assessed on the chemical composition and losses in silages treated with a bacterial inoculant, using laboratory silos. A 2 × 5 factorial arrangement (with and without inoculant and five elephant grass ratios) in a randomized blocks design with three replications was used. Interaction was observed in the sugarcane and elephant grass ratio × bacterial inoculant for crude protein (CP) and pH. The other variables were influenced only by the increasing proportions of elephant grass. The contents of dry matter, neutral detergent fiber corrected for ashes and protein, acid detergent fiber, insoluble protein in acid detergent fiber, hemicellulose and lignin in the silages increased linearly with the proportions of elephant grass. The water soluble carbohydrate contents and dry matter in vitro digestibility of the silages decreased linearly with the increase in the proportion of elephant grass. The mean value of ammonia nitrogen in relation to total N was 7.0% (% of DM). The CP values of the inoculated and non-inoculated silage fitted linear models. The highest CP content was observed in the silage treated with inoculant. The pH values of the silages, with and without inoculant, fitted quadratic and linear models, respectively. The lactic acid, propionic acid and butyric acid contents were not influenced by the elephant grass ratios, while the acetic acid content, for the non-inoculated silages, and ethanol decreased linearly with the increase in elephant grass. The ratio of 25%
