Nutrient Management in Mixed Specie Pastures for GOATS An Peischel Small Ruminant Specialist (Goats) Cooperative Extension Service Tennessee State University and University of Tennessee Phone: 615-963-5539
Sustainability through Biodiversity • Persists over generations • Flexible • Meets needs - present / future • Renewable resources used wisely • Pollution rate minimal
Ecosystem Foundation Blocks • Succession • Water cycle • Mineral cycle • Energy flow
Ecosystem Foundation Blocks • Succession • Change and development • Complex, stable communities • Competition, interdependence & adaptation • Water Cycle • Maximum use of rainfall • Minimize erosion • Percolation / infiltration
Ecosystem Foundation Blocks • Mineral Cycle • Effective cyclic pattern • Biological soil – atmospheric interaction • Continuous decomposing plant & animal residues • Energy Flow • Carbon cycle • Keeps all processes of life functioning • Solar power • All living things depend upon plants to harvest (capture) energy from sun & convert it to a useable form
Nutrition • Energy and protein levels in balance to reflect stage of • Vitamin and mineral requirements are being met production • Environment / weather • Breed • Stage of production • Quality of diet • Age and sex of goats • Body weight and body condition • Activity and exercise

Recommendation: 1 to 2 goats per head of cattle J-M Luginbuhl
Electric Fencing(Portable Solar Powered) - Maximize utilization of forage - Allocation based on forage quality and physical condition of goat - Manage individual or mixed plant species - Maintain healthy environment for vegetation and livestock
Disease prevention • Fecal analysis • Strategic vaccinations • Hoof care • Biosecurity Health
Management • Vegetation – browse, pasture, woodlands • Source alternative feedstuffs • Fencing • Health (disease prevention, foot problems, internal parasites) • Facilities • Dogs – guardian / herding • Behavior • Transportation
