The current study aimed to evaluate the application effects of the preactivated Lactobacillus buchneri and urea on the fermentative characteristics, chemical composition and aerobic stability in corn silages. The design was completely randomized, in a 6 × 5 factorial arrangement, with six types of additive and five opening times. The treatments consisted of corn silage; corn silage with freeze-dried inoculant; corn silage with freeze-dried inoculant +1.0% urea; corn silage with activated inoculant; corn silage with activated inoculant +1.0% urea, and corn silage with 1.0% urea. Populations of lactic acid bacteria stabilized at the 70th day, with average values of 8.91 and 9.15 log cfu/g for corn silage with freeze-dried inoculant +1.0% urea and corn silage with freeze-dried inoculant, respectively. In contrast, the silages without additives showed significantly lower values of 7.52 log cfu/g forage at the 70th day. The silages with urea (isolated or associated with the inoculant) increased the total nitrogen content. The maximum temperature values were highest in the corn silages without additives, indicating that these silages were more prone to deterioration. The use of Lactobacillus buchneri activated proved to be more efficient in improving the fermentative profile of corn silages than the freeze-dried inoculant. The use of urea as an additive reduced the losses and improved the nutritional value and aerobic stability of corn silages. Additionally, the combination of Lactobacillus buchneri activated and urea may be used as a technique to improve the fermentative profile, chemical composition and aerobic stability of corn silages.

Changes in the microbial community are closely related to the fermentation of silage. However, how host genetic variation shapes the community structure of the silage microbiota and its metabolic phenotype is poorly understood. The objective of present study was to evaluate the effects of the application of the homo-fermentative Lactobacillus plantarum and hetero-fermentative Lactobacillus buchneri strains to lucerne silage on the fermentation characteristics, aerobic stability, and microbial community and their correlations. The three silages treated with L. plantarum or L. buchneri were well preserved and had significantly lower pH values, butyric acid, propionic acid, and ammonia-N concentrations, and significantly higher residual water-soluble carbohydrate, dry matter and lactic acid contents than the controls. The treated groups had more lactic acid bacteria and lower quantities of other bacteria in their microbial communities. Inoculation of lactic acid bacteria influenced the abundances of other bacteria and controlled the silage fermentation characteristics. L. buchneri inhibited the abundance of Enterobacter_ludwigii to increase the crude protein content, L. plantarum improve the neutral detergent fibre content by affecting the abundance of Arthrobacter_sp._Ens13. In conclusion, the application of L. plantarum and L. buchneri improved the quality of lucerne silage fermentation, and L. buchneri resulted in greater improvements after aerobic exposure.

ABSTRACT The effects of various compounds on the aerobic stability of silages were evaluated. It has been observed that inoculation of whole-crop maize with homofermentative lactic acid bacteria leads to silages which have low stability against aerobic deterioration, while inoculation with heterofermentative lactic acid bacteria, such as Lactobacillus brevis or Lactobacillus buchneri, increases stability. Acetic acid has been proven to be the sole substance responsible for the increased aerobic stability, and this acid acts as an inhibitor of spoilage organisms. Therefore, stability increases exponentially with acetic acid concentration. Only butyric acid has a similar effect. Other compounds, like lactic acid, 1,2-propanediol, and 1-propanol, have been shown to have no effect, while fructose and mannitol reduce stability.

Silage Inoculants

Aerobic spoilage of silages occurs frequently and is undesirable because it reduces both its nutritive and hygienic quality. Silage inoculants containing heterofermentative lactic acid bacteria, like Lactobacillus buchneri, have already been proven to improve aerobic stability by augmented production of acetic acid, which inhibits yeasts. In this study, the effect of L. buchneri on fermentation characteristics and aerobic stability of alfalfa-ryegrass silage, red clover silage and maize silage was assessed using microsilos. Two dosages, 1×105 and 3×105 cfu g-1 of fresh matter, were compared to untreated control silage. Inoculation with L. buchneri clearly altered the fermentation characteristics of alfalfa-ryegrass and red clover silage, resulting in a significantly higher aerobic stability at both dosages. The effects of L. buchneri inoculation on maize silage were less clear, but nevertheless the aerobic stability of maize silage inoculated with 1×105 cfu g-1 of fresh matter was significantly higher compared to the untreated silage.

Silage Production

Whole-crop rye harvested before maturity represents a valuable forage for silage production. Due to the scarcity of data on fermentation characteristics and aerobic stability (ASTA) and the lack of information on mycotoxin formation during aeration of early-cut rye (ECR) silage after silo opening, we evaluated the effects of different additive types and compositions. Wilted forage was treated with various biological and chemical additives, ensiled in 1.5-L glass jars and stored for 64 days. Fermentation pattern, yeast and mould counts and ASTA were determined at silo opening. In total 34 mycotoxins were analysed in wilted forage and in silage before and after 240 h of air exposure. Chemical additives caused the lowest dry matter (DM) losses during fermentation accompanied with the lowest ethanol production and the highest water-soluble carbohydrate concentration. Aerobic deterioration, which started within two days after silo opening in silage left untreated and inoculated with homofermentative lactic acid bacteria, was prevented by the combined use of hetero- and homofermentative lactic acid bacteria and the chemical additive containing sodium nitrite, hexamethylene tetramine and potassium sorbate. Moreover, these two additives largely restricted the formation of the mycotoxin roquefortine C to < 0.05 mg kg−1 DM after aeration, whereas untreated silage contained 85.2 mg kg−1 DM.
