“…When exposed to air, high mould counts (10 6 cfu/g of silage) were observed in the control silage while no mould was detected in the inoculated silage (Meeske et al, 1999). McAllister et al (1998) reported that after 15 days of aerobic exposure, no moulds were detected in the lucerne silage inoculated with L. plantarum and E. faecium. Besides yeasts and moulds, the other contaminants associated with aerobic spoilage activity in silage are Bacillus spp.…”

“…Although the effects of inoculants on the preservation and nutritive value of silage have often been inconsistent, positive outcomes such as higher lactate:acetate ratios, lower ammonia N, decreased DM losses, increased digestibility, improved aerobic stability and enhanced growth performance have been reported (Henderson, 1993;McAllister et al, 1995McAllister et al, , 1998Zahiroddini et al, 2004). Most available inoculants consist of selected strains of homofermentative LAB, such as Lactobacillus plantarum, Pediococcus sp.…”

A new probiotic, bacteriocin-producing strain of Enterococcus faecium EF9296 (isolate of our laboratory) was used in grass ensiling as an inoculant. The antimicrobial effect as well as the nutritive quality of silage was evaluated along with the aerobic stability test. Grass was ensiled with EF9296 strain (109 colony-forming units per gram of fresh material) and the silage without EF9296 was also prepared. The silages were processed in 1-litre plastic bottles. The samples were collected at days 0–1 (start of experiment), 7, 14 and 105 of ensiling to check the microbial status and chemical parameters of silage. At the end of ensiling period (day 105) the silages were subjected to an aerobic stability test for 7 days. The EF9296 strain survived and colonized the silage in sufficient counts (109–1010 cfu/g). The total counts of enterococci and lactic acid bacteria were increased. In the silage inoculated with EF9296 strain, a reduction in E. coli, enterobacteriae, staphylococci and Bacillus-like bacteria was noted mainly at day 7 and 14 of ensiling. Moreover, the counts of Listeria and moulds were reduced during the aerobic stability test. The silage inoculation resulted in a more rapid drop of pH, higher level of lactic acid and in a decrease in the concentration of acetic and butyric acid. The effect of E. faecium EF9296 on the value of pH was prolonged until the end of the experiment (including the aerobic stability test, below 4.3). During the whole ensiling period an increase in DM content in the experimental silage was detected. The E. faecium EF9296 strain represents a promising silage additive to produce silage of good quality and/or to prevent silage contamination.

“…As a viable alternative to maintain the soil fertility, the use of grass and legume consortium has deserved prominence, especially with those of the Stylosanthes genus (Paciullo, Aroeira, Alvim, & Carvalho, 2003;Pariz et al, 2017). air at the ensile time (McAllister et al, 1998). It is believed that these problems can be minimized by ensiling mixed pastures, which can improve nutritional value of the feed and minimize fermentation losses.…”

The chemical composition, fermentation profile, microbial population and dry matter recovery were evaluated in marandu grass silages containing different levels of Stylo legume cv. Campo Grande treated or not with microbial inoculant. A 4 × 2 factorial arrangement (four levels of Stylo legume, with and without microbial inoculant) was used in a completely randomized design with four replications. The levels of Stylo legume used were 0, 10, 20 and 30% of the weight in the natural matter. The marandu grass was harvested at 70 days of regrowth and the Stylo legume at the pre-flowering stage. It was observed the effect of interaction between levels of Stylo legume and microbial inoculant on dry matter content, effluent losses, dry matter recovery and yeast and molds populations. The dry matter content of the silages with and without inoculant increased (P < 0.05) linearly with the addition of Stylo legume. A linear decreasing effect was observed for neutral detergent fiber contents and a linear crescent effect for the crude protein contents of the silages with addition of Stylo legume. The pH values had a quadratic effect with addition of Stylo legume, with a maximum value of 4.16 in the inclusion of 12.25% of Stylo legume. The LAB population increased linearly with an increase in the levels of Stylo legume. The dry matter recovery increased linearly with the addition of Stylo legume, in the silages without inoculant. It is concluded that the consortium of marandu grass with Stylo legume improves the chemical composition, fermentation profile, and decrease the dry matter losses of the silages, regardless of the use of microbial inoculant.

“…Segundo McAllister et al (1998), embora a alfafa apresente alto valor nutritivo, são encontradas características indesejáveis para o adequado processo de fermentação. Nesta forrageira, o momento ideal de corte é quando 10-25% dos perfilhos se apresentam floridos.…”

RESUMO -A cultura de alfafa (19% de MS), cortada com 10% dos perfilhos floridos, foi armazenada em 32 silos experimentais confeccionados a partir de baldes plásticos portando válvulas. A alfafa picada foi homogeneizada e submetida a quatro tratamentos com ou sem a adição de 12% de polpa cítrica peletizada: controle, Sil-All (S. Effects of Microbial Inoculants on Chemical Composition and Fermentation Characteristics of Alfalfa Silage Added with Citrus PulpABSTRACT -Alfalfa crop (19.0% DM) was harvested at 35 days and ensiled in 32 plastic experimental silos, consisting of four treatments with or without 12% of citrus pulp: control, Sil-All (S. faecium, P. acidilactici, L. plantarum, amylase, hemicellulase, and cellulase), Silobac (L. plantarum, S. faecium, and Lactobacillus sp.) and Pioneer 1174 (S. faecium and L. plantarum). Silos were opened 133 days after ensiling and sampled to proceed chemical analyses. Only in citrus pulp-free silage, all inoculants increased ethanol concentration; Pioneer increased pH, and Silobac decreased acetic acid concentration, compared to control. Independently of citrus pulp, all inoculants decreased DM losses; Silobac and Pioneer decreased IVDDM, and Pioneer increased NH 3 -N. Inoculants did not influence lactic, propionic and butyric acids concentrations and neither aerobic stability. Citrus pulp improved chemical composition and fermentation characteristics, but worsened DM losses and aerobic stability.
