This stabilization can be obtained by dry mode or by silage process. The objective of this article was to present in which degree these various techniques will modify the food value of fodder and more precisely the contents of parietal components; we evoked in our case pressed sugar beet pulp, dehydrated pulp in the form of pellets and ensiled pulp. The got results made it possible to deduce in the case of the ensilage which the microbial activity favored the hydrolysis of the most soluble substances of fiber during fermentation that and by consequence it cause a drop in the content of fiber to neutral detergent NDF and of Hemicellulose on the other hand this lactic fermentation made increase the content of cellulose, ADF and lignin. Also the values of the NDF, the ADF and the ADL are higher in the silages in balls of 450Kg by comparing them with the bags of ensilages of 50Kg on the other hand the contents of hemicellulose and cellulose is slightly lower in the balls of 450 kg than in the bags of 50 kg. This study as made it possible to say as the contents of the ADF, the NDF, the ADL, cellulose and hemicellulose in the pulp preserved by silage are approximate to the contents of pulp on the outlet side of the press (T0) and are higher than the contents in pellets . Key Words: Sugar beet pulp, silage, drying, NDF, ADF, ADL. _______________________________________________________________________________________________ 1. INTRODUCTION The sugar beet after its reduction in cossettes and pressing during the industrial process becomes, a combination of two matrices, the juice which will be transformed into sugar and pressed pulps which are heterogeneous structures made up mainly of structural glucids, and contain the major part of the parietal components: cellulose, hemicellulose and lignin. They compose together the fraction called “vegetable walls” quantified in the form of “NDF”. The vegetable matters rich in fiber are frequently introduced into food of cattle in particular for their beneficial effects on digestive operation [1] like for their energy contributions. In the ruminants, differences in the quantity and the physical and chemical properties of fiber in food can affect the performance and the productivity of animals, in particular to deteriorate fermentations in the paunch, metabolism, lipid level in milk produces, and finally long-term animal health [2] .
