When sourcing goat plastic floors, the primary focus should be on material composition and structural load-bearing capacity. High-quality floors are typically made from 100% virgin Polypropylene (PP), which offers superior impact resistance and anti-aging properties compared to recycled plastics. Ensure the load-bearing capacity is at least 200-300kg per square meter to accommodate multiple adult goats. Additionally, the slot size (leakage hole) should be approximately 1.5cm to 2.0cm; this is the 'golden ratio' that allows manure to fall through easily while preventing goat hooves from getting stuck or injured.
