Total mixed ration silage has been used as a strategy to optimize the use of dry and wet feed in ruminant feeding. Another promising technique is reallocation, which allows producers divide ensiled material large silos into smaller units that can be easily transported marketed. Thus, this study aimed improve food preservation through development total rations (TMRs) based on relocated sorghum (RSS) cactus pear for sheep diets. A completely randomized design was with five treatments (0, 15,...

Agroforestry systems (AFS) are considered alternative land use options to help prevent soil degradation and improve microbial biomass organic C status. However, it is unclear how different densities of babassu palm [Attalea speciosa (syn. Orbignya phalerata)], which an important tree in Northeast Brazil, affect the biomass. We investigated activity under AFS with associated Brachiaria brizantha grass. Soil (MBC), N (MBN), MBC:total ratio, fluorescein diacetate hydrolysis dehydrogenase showed...
