Similar results were obtained with the silages of the wheat of the milk stage. During storage pH values decreased; lacticacid content peaked after 3 months of storage and then decreased whereas the content of acetic acid increased constantly.Table 2 gives the results of the aerobic stability test of the various silages at different storage periods. In general, aerobicstability of all three silage types improved with time as apparent from stable pH values compared with the fresh silages,lower CO2losses, smaller populations of yeasts and molds and better sensorial appraisal. For the corn silages results werenot significant because of high variability among triplicates which resulted in high standard errors.In the regression analysis of the corn silages, storage time effect was significant for DM content (P=0.002), DM losses(P=0.0009), acetic acid (P
