Resumen:
The relocation of silage involves moving silage from one location and/or silo
to another, aiming to meet the needs of the rural producer. The use of inoculant in
reallocated silage can improve the fermentative profile, and fermented milk can be a
source of inoculant and beneficial lactic acid for fermentation in reallocated silage. Thus,
this study aimed to evaluate the use of fermented milk in the quality of sesame silage
reallocated in different storage periods. A completely randomized design with five
replications was used, in a factorial scheme (3 × 4). The first factor of reallocated sesame
silage: without additive, with commercial inoculant, and with fermented milk. The second
factor was determined by the silo opening time after the silage was relocated: at 15, 30,
60 and 90 days after relocation. Experimental silos (PVC tube) with a capacity of 500
kg/m³ of silage storage were used. Data were subjected to analysis of variance and means
analyzed by the Tukey test compared with significance (P <0.05). To characterize the
quality of the silage, the parameters analyzed were: losses and recovery of dry matter;
buffer capacity and soluble carbohydrates; pH and ammoniacal nitrogen, volatile fatty
acids; microbiological population; chemical composition. For dry matter, an average of
24.61 kg-1 DM was observed with the use of the inoculant L. buchneri in the period of
60 days, for protein it presented a higher value in the opening of 15 days with 12.17 kg-
1 DM with the use of fermented milk, for mineral matter the lowest value for the treatment
without additive with 7.57 kg-1 DM. As for pH, it presented lower values for the
treatment with L. buchneri and fermented milk with 4.22 and 4.01, respectively. For lactic
acid bacteria, the best result was obtained after opening of 15 and 30 days for treatment
with L. buchneri inoculant with 6.74 and 5.80 CFU/g. It is recommended to use a
commercial inoculant in the relocated sesame silage, as it presents better results.
