“…The use of moisture absorbent additives is a strategy recommended for producing tropical grass silage with minimum effluent production and improved chemical composition, intake, and dry matter digestibility (Daniel et al 2019). The by-products of the extraction of oil from fruits of oleaginous plants are characterized by a high dry matter content (>85%), and, when included in elephant grass silage as additives, they improve fermentation and the silage nutritive value (Menezes et al 2016;Santos et al 2014;Ribeiro et al 2014;Van Cleef et al 2012).…”

ABSTRACT Elephant grass silages have high moisture content, causing nutrient loss, mainly by effluent production. The use of moisture absorbent additives, such as patauá, Oenocarpus bataua meal, can be a strategy to reduce losses in these silages. The aim of this study was to determine the fermentation losses, microbiological composition, fermentative characteristics, and chemical composition of elephant grass silage with increasing levels of inclusion of patauá meal. The experiment was conducted in a completely randomized design, with four concentrations of patauá meal (7%, 14%, 21%, and 28%, based on fresh matter) and a control without patauá, and five replicates. The elephant grass was collected manually after 60 days of growth. After chopping, the grass was homogenized, mixed with the patauá meal according to the established treatments, and ensiled in experimental silos of 15 L. The inclusion of patauá meal in elephant grass silage had positive effects on the chemical composition and effluent loss. It significantly increased dry matter, organic matter, crude protein, nitrogen insoluble in neutral detergent and acid, ethereal extract, lignin, and non-fibrous carbohydrates of the silages. It also reduced effluent losses, neutral and acid detergent fiber contents, and cellulose. Our findings contribute towards reducing the environmental impact caused by the production of effluents during ensilage of tropical grasses and providing a potential use for the residue from the production of patauá oil, thus avoiding disposal in the environment.

“…Nevertheless, data from studies evaluating the use of this type of additive are quite controversial (Muck 2004;Gimenes et al, 2006;Zopollatto et al, 2009;Basso et al, 2012;Santos et al, 2013;Lara et al, 2016;Mohammadzadeh et al, 2016). Although bacterial additives can favor dry matter recovery from ensiled material (Kung Júnior et al, 2003), co-products of the biofuel industry may also be used as alternative additives to improve the fermentation process (Van Cleef et al, 2012;Martins et al, 2014;Gomes et al, 2015).…”

Glycerol, the main constituent of crude glycerin, has high energy efficiency and may provide energy to microorganisms in silage. Therefore, we evaluated the effect of including crude glycerin (CG) and a bacterial inoculant on the chemical composition, losses, fermentation profile, microbial population and aerobic stability of rehydrated corn grain silage. The dry corn grain (800 g kg-1 dry matter (DM)) was milled to 5 mm and rehydrated with water and glycerin to achieve 32.5% moisture content. Crude glycerin was added at 0, 75, 150 and 225 g kg-1 (natural matter (NM)), with or without bacterial inoculant. The experiment was randomized, and included three replicates in a factorial scheme, with or without bacterial inoculant, four crude glycerin levels and five fermentation periods. CG inclusion in silage decreased the nitrogenous and fibrous fractions, gas losses, DM recovery, and microbial growth. However, CG addition increased effluent and total DM losses. Treatment with 0 and 75 g kg-1 CG (NM) resulted in lower pH (4.6; 4.28) at 64 days of fermentation. Silage without CG remained stable to oxygen after 12 days. The bacterial inoculant did not influence the variables analyzed. We conclude that CG inclusion, bacterial inoculant or a combination of these additives is not recommended for this type of material. Nevertheless, rehydration with water (125 g kg-1 DM) is an alternative for storage of corn grain silage through the ensiling process.
