Assessment of Maize Silage Quality under Different Pre-Ensiling Conditions
Abstract
:1. Summary
- Evaluate the effectiveness of a set of fermentative quality indexes to estimate the quality of fermentation of whole-plant maize silage in a lab-scale ensiling system [15].
- Verify the influence of the FAO class of maize hybrids harvested at different maturity stages and grown in agronomic areas with different yield potentials on their ensilability capacity. The latter was assessed using the fermentative profile and fermentation quality indexes tested in a previous trial [16].
- Evaluate the effectiveness of a multivariate approach and multiple linear regression in predicting the potential of freshly harvested maize (FHM) to ensure silage fermentation quality based on the chemical composition of the harvested whole-plant maize [17].
- Assess the effect of hetero- and homo-fermentative inoculants on maize silage fermentative quality and aerobic stability under different conditions—progressive delay in silo sealing, different maturity at harvest and different exposure times to air after the opening of the silo—and propose a predictive model of maize silage aerobic stability potential based on the FHM composition using a nomogram ranking the risk of silage degradation [13,14].

2.3. Dataset Description
- Sheet 1, “dictionary keys”, contains details of the variables described in Sheets 2, 3 and 4. Column A is the variable name, Column B is the variable description—including the unit of measurement and the possible values for categorical variables—and Column C reports some details or explanations.
- Sheet 2, “elab.all”, reports the trial number (#) and reference of the published articles (Columns A and B), the sample id (Columns C and D), the tested theses (Columns E–O), the type of data as singular or arithmetic mean (Trial #2.a.1.a and Trial #2.b) from different silage layer values (Columns P), the FHM composition (Columns Q–Y), an empty Column (Z), the silage composition (Columns AA–AS), the DM loss (DMloss, %) and DM recovery (DMr, %) (Columns AT and AU), FQI (Column AV), porosity and density (Columns AW–AX), and reference methods used for FHM and silage sample analyses (Columns AY and AZ).
- In Sheet 3, “elab.temp”, Columns A to P report the corresponding columns (A–P) of sheet “elab.all” for a proper sample link. Columns Q to S report the indicator (event = 1) for aerobic instability, the time to event for aerobic instability, and the cumulative temperatures (TCUM) of aerobically unstable samples, respectively.
- Sheet 4, “elab.buckets”, reports data only for Trial #2.a.1.a and Trial #2.b. Columns A to P report the corresponding columns (A–P) of sheet “elab.all” for a proper sample link. The FHM (Columns Q–Y), silage Spl (Columns AA–AS), silage OT1 (Columns AU–BM), silage OT3 (Columns BO–CG) and silage OT5 (Columns CI–DA) chemical traits are reported. DMloss, DMr, density and porosity are reported in Columns DC–DF. The reference methods used for FHM and silage sample analyses are reported in Columns DH and DI.
