“…Since crude glycerine does not have these components (only glycerol, methanol, and lipids), its addition results in the dilution of these components on a DM basis. A similar result was observed by Orrico Junior et al 2017and Cunha et al (2020) with the addition of different doses of crude glycerine to tropical grass silage. The effect of the interaction between the degree of crude glycerine purity and glycerol content on the NDF and TC contents can be explained by the change in the volume of crude glycerine that was needed to achieve the target percentages of glycerol (Table 1); the opposite occurred for the EE content, which is present at high levels in crude glycerine with low degrees of purity (Zavarize et al, 2014).…”

“…According to Hong et al (2010), some bacteria species may use glycerol as an energetic substrate for the production of organic acids, among them, lactic acid. In a recent research, Cunha et al (2020) also observed improvements in the production of lactic acid and the nutritional value of Tifton 85 silages, even when the forage has high levels of dry matter, which is a condition that hampers the fermentation process.…”

We aimed to evaluate the effects of crude glycerine purity and levels of glycerol on the fermentative profile, microorganisms counting, and nutritional value of Piatã grass silage. The experiment was carried out in a 3×3+1 completely randomized factorial design using three different types of crude glycerine [low purity (40% of glycerol), medium purity (60% glycerol), and high purity (80% glycerol)], three doses of glycerol (20, 40, and 60 g/kg DM), and a control (no crude glycerine added) as an additional treatment, which were stored for 80 days. Statistical differences were not observed on fermentative losses of the treatments tested. The increase of glycerol doses resulted in higher levels of non-fibrous carbohydrates and lower levels of fibre components. The addition of low-purity crude glycerine increased the levels of fat and in vitro digestibility of silages. The highest levels of lactic acid and acetic acid occurred in the treatments with 60 g/kg of glycerol when using crude glycerine with a low purity. The lowest lactic acid content was observed in the control treatment and in the lowest dose of glycerol. The highest glycerol dose (60 g/kg), associated with the lowest degree of crude glycerine purity (40%) resulted in the greatest nutritional value and provided the best silage conservation.

“…There are reports on the literature on the lack of efficiency of homofermentative microbial additives in reducing fermentative losses in tropical grass silages. Cunha et al (2020) and Vendramini et al (2016) also observed no differences in the recovery of DM of silages inoculated with commercial microbial additives that contained P. pentosaceus and L. plantarum. Likewise, Orrico Junior et al (2020) did not observe improvements in DM recovery values when silages were inoculated with P. pentosaceus and L. buchneri.…”

The conservation of elephant grass cultivar Capiaçu in the form of total mixed ration (TMR) silage can help to improve the quality of the fermentative process and optimize feed management. However, the best cutting age of grass and the necessity of using microbes-enzymatic additives to aid in the process have not been determined thus far. Therefore, the objective of this study was to evaluate cutting age and different microbes-enzymatic additives on the fermentative and nutritional quality of total mixed ration (TMR) silages based on BRS Capiaçu. A completely randomized design was used in a 3×3 factorial scheme, with three cutting ages of grass (60, 90, and 120 days of regrowth), associated with three types of additives [CON (control), HOM (homofermentative inoculant + fibrolytic enzyme), and COMBO (homofermentative inoculant + heterofermentative inoculant + fibrolytic enzyme)]. The fermentative losses, the production of organic acids, chemical composition, and the aerobic stability of the tested silages were measured. The TMR silages containing 60-day-old grass showed the lowest dry matter contents, highest effluent production, and lower aerobic stability. The COMBO inoculant application provided higher acetic acid contents and greater aerobic stability of the 90-and 120-day-old grass silages. The highest lactic acid concentrations were observed in silages produced with the 60-and 90-day-old grass silages. It is concluded that the TMR produced with BRS Capiaçu at 90 days of age and in association with COMBO is the best option to balance the nutritional and fermentative quality of this type of silage.

“…La glicerina bruta es capaz de reducir las pérdidas en la fermentación sin acciones deletéreos sobre los inoculantes microbianos, produciendo mayores concentraciones de ácidos lácticos, que provocan disminución en la producción de ácido acético, mejorando así los parámetros de fermentación y nutricional de los forrajes conservados (Cunha et al, 2019). Dicho el potencial de la glicerina bruta como alternativa de modular la fermentación y la necesidad de alternativas alimenticias de bajo costo, se propuso como objetivo en la presente investigación determinar la eficiencia de la glicerina bruta en la reducción de pérdidas fermentativas de ensilajes de pasto Pennisetum purpureum.…”

El objetivo de esta investigación fue verificar mejoras en el proceso fermentativo del ensilaje de Pennisetum purpureum cosechados en tres edades de corte con la inclusión de diferentes dosis de glicerina bruta (GB). El experimento fue realizado en un delineamiento completamente al azar en esquema factorial 4x3x3, cuatro dosis de glicerina bruta (0, 10, 20 y 30% de la materia seca [MS] ensilada) y tres edades de corte (30, 45 y 60 días) con tres repeticiones por tratamiento (minisilos). Fueron determinados, pH, producción de efluente (PE), pérdidas por gases (PG) y pérdidas de materia seca (PMS). Los resultados fueron sometidos a un análisis de varianza al 5% de probabilidad. Se ha verificado mejoras en el proceso fermentativo del ensilaje de P. purpureum con la adición de glicerina bruta y reducción de pérdidas. PE se redujo 12,05% para las dosis de 30% de glicerina bruta en el primer corte, para el segundo corte, se redujo del 17,63% en relación al T1 (Testigo) 0% de GB. Las reducciones en las PG en el primer y segundo corte fueron de 22,30% y 82,16% respectivamente, así también la mayor dosis (30% GB) fue la que arrojo mejores resultados con una reducción del 57,3 por ciento. En cuanto a PMS, el ensilaje producido con la mayor dosis de GB (30%) fue el que produjo mejor resultado comparando con las demás dosis. GB puede ser utilizada en el ensilaje de Pennisetum purpureum para promover mejoras en el proceso fermentativo y reducción de las perdidas cualitativas.
