Effect of microbial inoculants on the chemical composition and aerobic stability of Tanzania guinea grass silages

Abstract

The present study evaluated the effects of microbial inoculants on chemical changes and aerobic stability efficiency in Tanzania guinea grass silage. The treatments consisted of C: silage without inoculant; I: silage inoculated with Lactobacillus plantarum (CCT 0580) 8.0 x 109 CFU g-1, Bacillus subtilis (CCT 0089) 2.0 x 109 CFU g-1, and Pediococcus acidilactici (CCT 2553) 1.0 x 1010 CFU g-1, and L: silage inoculated with Lactobacillus plantarum (CCT 0580) 2.6 x 1010 CFU g-1 and Pediococcus pentosaceus (CCT 7659) 2.6 x 1010 CFU g-1. The experimental design was completely randomized, with five replications. There were no treatment effects on the nutritional composition of the silages, but both inoculants were effective in reducing the pH of the silage to 4.80 and 4.83 for I and L, respectively, compared with 5.04 for C. Silage with L had a lower ammonia nitrogen (N-NH3) content than the other silages (9.83%). Despite the lower pH values, the use of inoculants did not reduce fungal and yeast counts or improve the aerobic stability of Tanzania guinea grass silages.

Ensilados de Megathyrsus maximus: Efecto del horario de corte y de la inoculación microbiana

“…El mayor contenido de PB se asoció a los tratamientos con adición del inóculo, notándose el efecto de manera más sostenida en el ensilado de Mombasa, indicando menores pérdidas de compuestos nitrogenados. Similares resultados fueron expuestos por Bumbieris et al (25), quienes, al evaluar la inoculación con Lactobacillus plantarum y Pediococcus pentosaceus en ensilados del pasto Tanzania, registraron menores perdidas nitrogenadas, resultado que se atribuyó a la inhibición de las bacterias responsable de este proceso (32). Los ensilados de maíz y de Tanzania presentaron contenidos de PB semejantes en los horarios a.m. y p.m., pero en Mombasa, los mayores porcentajes de PB se presentaron en el material cortado en la mañana, lo que explica la interacción entre los factores horario de corte e inóculo.…”

Ciências agrárias: estudos fundamentais

“…Silagens de gramínea do gênero Panicum maximus capim Tanzânia, inoculadas com uma combinação de L. plantarum, Bacillus subtilis e Pediococcus acidilactici e outra com L. plantarum e Pediococcus pentosaceus, apresentaram maior redução no pH sem que interferisse na estabilidade aeróbica das silagens (Bumbieris Junior et al, 2021).…”

Effects of microbial inoculant on chemical compositions and in vitro digestibility of elephant grass-based silage

“…To reduce feeding cost and achieve higher quality of forage grasses for pig production, ensiling is an effective approach. The genus Bacillus is important in the initial phase of fermentation owing to its probiotic properties such as production of natural antibiotics and lactic acid, controlling of yeast growth, and hemicellulose and cellulose degradation (Junior et al, 2021). Importantly, with pH level remarkably reduced due to organic acid production of lactic acid bacteria, the growth of undesirable microorganisms was inhibited.…”
