“…Elephant grass (Pennisetum purpureum, Schum) is considered one of the most important tropical forages because of its high potential for biomass production, easy adaptation to diverse ecosystems and good acceptance by the animals. It is widely used to feed herds in the forms of pasture and especially as silage, because of its high soluble carbohydrate content that favors good fermentation (Patrizi et al 2004).…”

The objective of the present study was to assess the chemical and bromatological composition and in situ degradability of elephant grass silages inoculated with Streptococcus bovis isolated from cattle rumen. A complete randomized design was used with four treatments and six replications: elephant grass silage, elephant grass silage inoculated with 10 6 CFU/g Streptococcus bovis JB1 strains; elephant grass silage inoculated with 10 6 CFU/g Streptococcus bovis HC5 strains; elephant grass silage inoculated with 10 6 CFU/g Enterococcus faecium with six replications each. The pH and ammoniacal nitrogen values were lower (P<0.05) for the silages inoculated with Streptococcus bovis JB1 and HC5, respectively. The silage inoculated with Streptococcus bovis had a higher crude protein content (P<0.05) and there were no differences for the fiber contents in the silage. The (a)soluble fraction degradability, especially in the silages inoculated with Streptococcus bovis JB1 and HC5, had higher values, 30.77 and 29.97%, for dry matter and 31.01 and 36.66% for crude protein, respectively. Inoculation with Streptococcus bovis improved the fermentation profile, protein value and rumen degradability of the nutrients.

“…Based on the literature for tropical grasses, the DM content ranges from 157.8 to 280 g/kg (Patrizi et al, 2004;Ribeiro et al, 2008;Ávila et al, 2009;Silva et al, 2011). According to McDonald et al (1991), the optimum dry matter content for good quality silages ranges from 300 to 350 g/kg.…”

Microbial and fermentation profiles, losses and chemical composition of silages of buffel grass harvested at different cutting heights

-The present study evaluated the microbial population, fermentation profile, losses and dry matter recovery, and chemical composition of silages of buffel grass at different cutting heights. To evaluate the microbial fermentation dynamics, the treatments resulted from a 4 × 5 factorial combination consisting of 4 cutting heights and 5 fermentation periods, in a completely randomized design with three replications. The fermentation was evaluated at the end of 1, 3, 7, 15 and 30 days. The other characteristics of silages with 30 days were evaluated following a completely randomized design with four treatments, consisting of 4 cutting heights (30, 40, 50 and 60 cm), and five replications. Fermentation period and cutting height effects and interaction between both factors were observed on the populations of lactic acid bacteria (LAB), enterobacteria and molds and yeasts. The peak of development of LAB populations was observed on the seventh day of fermentation for the heights of 40 and 50 cm, with 8.25 and 8.30 log cfu/g, respectively. The pH values of silages ranged with different cutting heights, in which at the height of 50 cm the decrease was most pronounced. However, the pH values were similar between the cutting heights at the end of 30 days of fermentation. Quadratic relationship was observed between lactic acid concentrations and cutting heights. The crude protein content behaved linearly, initially showing 128.5 g/kg DM at 30 cm, decreasing as the cutting heights increased. The neutral detergent fiber and ether extract contents increased linearly with the cutting heights. Based on microbial populations, fermentation, losses and chemical composition, it is recommended to harvest buffel grass for silage from 50 cm on.

When compared to the others, elephant grass stands out in silages researches because of present high productivity and higher soluble carbohydrates concentration.…”
