(6b) Systems of Goat Management

1. Extensive System (Free Range): Goats roam freely to scavenge for food and water with little to no housing or medical care provided.
2. Intensive System (Zero Grazing / Confinement): Goats are completely confined in a housing structure where feed, water, and medication are brought directly to them.
3. Semi-Intensive System: A compromise where goats graze on managed pastures during the day and are sheltered in houses at night.
4. Tethering System: Goats are secured to a peg or tree with a rope, limiting their grazing radius, and moved periodically to new grass.
