Stubble Quality of Wheat Grown under No-Tillage and Conventional Tillage Systems, and Effects of Stubble on the Fermentation Profile of Grazing Ewes’ Ruminal Fluid

Conservation practices that involve leaving mulch on the soil are known to increase fertility. However, is an important source of feed for ruminant livestock. Accordingly, trade-offs between mulching and stubble uptake by livestock currently hot topics in research field. In this study, a comparison quality stubbles wheat grown no-tillage conventional tillage fields rumen fermentation characteristics Barbarine ewes grazing two was carried out. Samples were collected four times after grain harvesting. Immediately harvest, biomass slightly higher under than tillage. The displayed different behavior, with feeding at rate conservative stubble. This behavior seemed be adaptive strategy offset decline nutritional from no-tillage-grown wheat. Indeed, dry matter, protein, fiber, ash contents lower second sampling time. Consequently, concentration volatile fatty acid, propionic plots. did not cause any body weight impairment during two-month experimental period. At end grazing, practice found comparable system according amount residue remaining surface. Therefore, could used solve competition crops residues.
