What are the five types of sheep production systems?

The five types of sheep production systems include extensive, semi-intensive, intensive, purebred, and crossbred systems. Extensive systems rely on natural grazing over large areas with minimal inputs, while semi-intensive systems combine grazing with some supplemental feeding. Intensive systems involve high levels of feed input and close management, often in confined spaces. Purebred systems focus on breeding specific sheep breeds for quality traits, while crossbred systems aim to enhance production traits by crossing different breeds.
