The purpose of the current study was to evaluate the effects of inoculants on chemical composition, dry matter (DM) and neutral detergent fiber (aNDF) in vitro degradation, fermentative and effluent losses, microbiology, fermentative profile, and aerobic stability of sugarcane mini-silos. Treatments were randomly distributed to the mini-silos, in which: (1) Control (CON); (2) Lactobacillus buchneri (Lb), addition of Lb at 2.6 × 10 10 cfu/g; (3) Lactobacillus buchneri and Bacillus subtilis (Lb + Bs), addition of Lb at 2.6 × 10 10 cfu/g and Bs at 1 × 10 9 cfu/g; and (4) Chitosan (CHI), addition of 1% of CHI on wet basis of sugarcane ensiled. Treatments 2 and 3 were incorporated to the silage at 2 g/t of natural matter ensiled. Lb and Lb + Bs did not alter the in vitro degradation of DM and NDF. Chitosan incorporation increased the DM content (P = 0.013, 18.7 g/kg DM) and improved (P = 0.029, 45.6 g/kg DM) the NDF in vitro degradation of sugarcane silage. In addition, CHI incorporation showed higher (P = 0.002) DM content in silage than Lb and Lb + Bs. Microbial inoculants (Lb and Lb + Bs) reduced the total losses (P = 0.009) of sugarcane silage. Moreover, CHI incorporation showed lower (P = 0.001, 84.9 g/kg DM) total losses and higher (P = 0.031, 84.8 g/kg DM) dry matter recovery than Lb and Lb + Bs. Lactic acid bacteria concentration was increased (P = 0.001) with additives, and CHI incorporation showed higher (P = 0.001) lactic acid bacteria concentration than silages treated Lb and Lb + Bs. All additives decreased the ethanol concentration in sugarcane silage, but CHI showed lower (P = 0.002) ethanol concentration compared to Lb and Lb + Bs. Inoculants improved the aerobic stability of sugarcane silage. In general, the incorporation of CHI to sugarcane silage showed better results of NDF in vitro degradation and gas and effluent losses than Lb and Lb + Bs. Moreover,

“…However, chitosan showed no effect on silage ethanol though there was a lower numerical concentration in silos containing (0.41 g/kg DM) or not (0.05 g/kg DM) microbial inoculant. Rodrigues et al (2012) have already reported the lack of effect on ethanol concentration in silos with lower acetic acid concentrations.

We aimed to evaluate the effects of chitosan and microbial inoculant addition to sugarcane silage fermentation, gas and effluent losses, chemical composition, in situ dry matter (DM), neutral detergent fibre (NDF) degradation and aerobic stability. A completely randomized design with four treatments (n = 40) was performed. It was arranged in a 2 × 2 factorial scheme with chitosan [0 and 6 g/kg of sugarcane DM—1.66 g/kg of natural matter (NM)] and microbial inoculant (0 and 8 mg/kg on NM). Each g of inoculant contained 3.9 × 1010 UFC/g of Pediococcus acidilactici and 3.75 × 1010 UFC/g of Propionibacterium acidicipropionici. The addition of microbial inoculant increased lactic acid concentration in silos treated with chitosan. Furthermore, chitosan increased pH and tended to increase acetic acid of silage. In contrast, the inoculant decreased pH and acetic acid, besides increasing ethanol concentration. As chitosan addition increased DM recovery, inoculant addition decreased it. Chitosan decreased NDF and acid detergent fibre (ADF) level and increased DM degradation, while inoculant decreased DM content, DM and NDF degradation. In addition, chitosan improved the aerobic stability only in non‐inoculated silos. Thus, chitosan has a positive effect on silage fermentation, reducing fermentative losses, and improving silage chemical composition and degradation. Conversely, the addition of microbial inoculant negatively affected silage DM recovery, chemical composition, and its association with chitosan decreased the aerobic stability when compared to the exclusive use of chitosan.
