Chemical composition and nutrient degradability in elephant grass silage inoculated with Streptococcus bovis isolated from the rumen

Abstract

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.

“…The CP in EG was close to that obtained elsewhere (Nambi et al 2001) while NDF was close to 720 g/kg reported by Ferreira et al (2014). The relatively high CP in EG makes it a good feed.…”

“…Hasil serupa diperoleh pada silase rumput Tanzania (Panicum maximum cv. Tanzania) menggunakan bakteri Streptococcus bovis yang diisolasi dari rumen sapi menghasilkan meningkatkan protein kasar dari 5,51% menjadi 7,08% setelah fermentasi (Ferreira et al 2014) dan dari 9,13% menjadi 11,25% (Zanine et al 2016). Hasil yang lain dilaporkan oleh Naif et al (2016) pada silase rumput dengan taraf penambahan dedak padi dan jagung giling dengan taraf yang berbeda-beda.…”

“…However, its high cell walls and low water-soluble carbohydrates can cause a significant inhibition of the ensiling process. The dry matter yields of elephant grass vary between 15 and 30 ton ha -1 a year [1] . Despite this, this grass concentrates too much moisture content at its best nutritional stage, which caused a reduction in the silage quality due to the high proteolysis; moreover, there are substantial nutrient losses due to such moisture levels [2] .…”

“…Nevertheless, elephant grass is regarded as one of the most important tropical forages because of its high potential for biomass production, easy adaptation to diverse ecosystems and good acceptance by animals. Furthermore, it is extensively used to feed herds in the form of grazing [1] . However, its low crude protein content [3] and high structural carbohydrate contents [4] usually lead to the low nutritive value of silage.…”
