Semi-zero grazing is a term used to describe a type of livestock management system where animals are kept in confinement and fed on a mix of pasture and supplementary feed. However, there are several other terms that can be used interchangeably to describe this system. Some of the synonyms for semi-zero grazing include partial confinement, partial grazing, partial intensive management, and partial stall feeding. Essentially, these all refer to a system that combines elements of grazing and confinement to optimize the health and productivity of the animals while conserving resources. Whatever term is used, the focus is on balancing the needs of the animals and the environment with the practical realities of livestock management.
