“…In studies that enable differentiation, the addition of fibrolytic enzymes to bacterial inoculants has had a positive effect on silage quality, increasing in saccosoluble NDF and improving feed efficiency in feedlot cattle (Zahiroddini et al, 2004). In other studies, less well-defined enzyme cocktails added in conjunction with a complex mixture of inoculants accelerated the post-ensiling decline in pH but failed to improve the growth performance of steers (Addah et al, 2016). Lynch et al (2015) added cellulase and xylanase to corn forage before ensiling alone and in combination with a ferulic acid esterase-producing (FAE) silage inoculant and found that the combination resulted in a lower pH and higher WSC than the control silage after 70 d of ensiling.…”

Additives have been available for enhancing silage preservation for decades. This review covers research studies published since 2000 that have investigated the efficacy of silage additives. The review has been divided into 6 categories of additives: homofermentative lactic acid bacteria (LAB), obligate heterofermentative LAB, combination inoculants containing obligate heterofermentative LAB plus homofermentative LAB, other inoculants, chemicals, and enzymes. The homofermentative LAB rapidly decrease pH and increase lactic acid relative to other fermentation products, although a meta-analysis indicated no reduction in pH in corn, sorghum, and sugarcane silages relative to untreated silages. These additives resulted in higher milk production according to the meta-analysis by mechanisms that are still unclear. Lactobacillus buchneri is the dominant species used in obligate heterofermentative LAB silage additives. It slowly converts lactic acid to acetic acid and 1,2-propanediol during silo storage, improving aerobic stability while having no effect on animal productivity. Current research is focused on finding other species in the Lb. buchneri group capable of producing more rapid improvements in aerobic stability. Combination inoculants aim to provide the aerobic stability benefits of Lb. buchneri with the silage fermentation efficiency and animal productivity benefits of homofermentative LAB. Research indicates that these products are improving aerobic stability, but feeding studies are not yet sufficient to make conclusions about effects on animal performance. Novel non-LAB species have been studied as potential silage inoculants. Streptococcus bovis is a potential starter species within a homofermentative LAB inoculant. Propionibacterium and Bacillus species offer improved aerobic stability in some cases. Some yeast research has focused on inhibiting molds and other detrimental silage microorganisms, whereas other yeast research suggests that it may be possible to apply a direct-fed microbial strain at ensiling, have it survive ensiling, and multiply during feed out. Chemical additives traditionally have fallen in 2 groups. Formic acid causes direct acidification, suppressing clostridia and other undesired bacteria and improving protein preservation during ensiling. On the other hand, sorbic, benzoic, propionic, and acetic acids improve silage aerobic stability at feed out through direct inhibition of yeasts and molds. Current research has focused on various combinations of these chemicals to improve both aerobic stability and animal productivity. Enzyme additives have been added to forage primarily to breakdown plant cell walls at ensiling to improve silage fermentation by providing sugars for the LAB and to enhance the nutritive value of silage by increasing the digestibility of cell walls. Cellulase or hemicellulase mixtures have been more successful at the former than the latter. A new approach focused on Lb. buchneri producing ferulic acid esterase has also had mixed success in improving the efficiency of ...

“…The inoculant used was BIOTAL PLUS II® (Lallemand Animal Nutrition, Milwaukee, Wisconsin) that contained viable cells of the LAB Pediococcus pentosaceus 12,455 (homofermentative) and Propionibacterium freudenreichii R2453 (heterofermentative) and specific enzymes, which were expected to enhance fiber hydrolysis during ensiling [5]. The inoculant was applied following instructions; hence, it was expected to supply 100,000 CFU/gram of forage.…”

Alfalfa forage is difficult to ensile due to low water-soluble carbohydrate content and high buffering capacity. The objective was to assess at Chapingo, Mexico, during the rainy season effects of combinations of harvest hours (08:00, 14:00), wilting time (0, 1, 2 h) and bacterial inoculants on the quality of silage made of alfalfa and orchard grass forage, made in 200-L containers. The experiment was conducted in three phases with two replicates per phase. Variables measured in freshly cut forage and silages were dry matter content (DM), buffer capacity, pH, and alcohol soluble carbohydrates (ASC). Silos remained sealed during 60 d, and additional variables measured in silage were aerobic stability, NH3 -N and in vitro disappearance of DM. In forage harvested at 14:00 h, DM and ASC contents were higher; pH and buffering capacity were not affected by harvest hour; in silages made of that forage, NH3-N levels were lower, while ASC contents and in vitro disappearance of MS were unaffected by harvest hour. Treatments with inoculants were less aerobic stable for 5 days when made of forage harvested at 08:00 h but more stable when made of forage harvested at 14:00 h. Harvesting at 14:00 h was advantageous as silage presented higher DM and ASC contents.

“…Al considerar el tiempo de muestreo de manera específica, se observó que a los 30 días el pH disminuyó en comparación con los resultados obtenidos a los 15 días, esto se debe posiblemente a la producción de ácido láctico por parte de microorganismos homofermentadores como Lactobacillus plantarum (Filya, 2003ay Addah et al, 2016 aspecto que refleja un adecuado proceso de ensilado (Jaimes et al, 2009). Resultados similares son reportados por la literatura (Filya, 2003b;Jalč et al, 2009;Corral-Luna et al, 2011;Addah et al, 2011;Addah et al, 2016;Joo et al, 2018).…”

Con el fin de evaluar el efecto de la inoculación de L. plantarum en la fermentación, conservación y calidad del ensilaje de maíz (Zea mays), se realizó el ensilaje de 32 bolsas con forraje a diferentes dosis de inoculado de L. plantarum (0, 5, 10, 15 ml) y tiempo de muestreo (15, 30, 45 días), en un diseño completamente al azar. Se estudió el pH, temperatura y unidades formadoras de colonias (UFC). Además de las características bromatológicas. El tiempo de muestreo resultó ser significativo (p<0,01) para el pH, siendo a los 30 días el de menor valor promedio (3,65). Se observó una temperatura mayor (27oC) a los 15 días de muestreo (p<0,01). La aplicación de L. plantarum en los componentes bromatológicos no incidió estadísticamente a excepción de la materia seca donde T3 a los 15 días presentó mayor promedio (23,65%). Además, los promedios máximos fueron para proteína cruda (10,71%) en T2 a los 30 días; estrato etéreo (2,36%) en T1 a los 45 días; fibra cruda (37,30%) en T3 a los 45 días; ceniza (9,28%) en T2 a los 30 días y energía digestible (2,41 Mcal/Kg) en T2 a los 15 días. Se concluye que la inoculación microbiana permite acelerar el proceso de conservación del forraje.
