ABSTRACT
It was determined the fibrous fraction (NDF, ADF, cellulose, hemicellulose and lignin) in green forage and pearl millet silages (CMS-1, BRS-1501 and BN-2). The genotypes were planted at Embrapa Milho e Sorgo, ensiled in PVC laboratory silos and evaluated after one, three, five, seven, 14, 28 and 56 days. NDF values ranged from 46.96 to 62.43% and ADF from 27.86 to 34.56%. Hemicellulose contents in green forage were significantly lower than in silages after 56 days ensiling. The NDF, ADF, cellulose, hemicellulose and lignin mean values in green forages and silages after 56 days of fermentation were 60.76 and 51.8%, 33.58 and 31.54%, 29.25 and 27.66%, 27.18 and 20.26%; 4.33 and 3.89%, respectively. The NDF and ADF average values found in this work were lower than those reported in other studies. The hemicellulose fraction contributed as an additional subtract source to the fermentation process. BRS-1501 genotype showed the lower NDF and ADF contents.
