Livestock producers in McDowell County face unique challenges due to the region’s variable terrain, changing seasonal forage quality, and occasional nutrient deficiencies in local pastures. Proper supplementation is a key management practice that supports animal health, productivity, and long-term pasture sustainability.
Why Supplementation Matters
Even when livestock are on pasture, forage alone often doesn’t meet all of their nutritional needs—especially during critical times like:
-
Late winter and early spring, when pastures are sparse.
-
Breeding and lactation periods, when nutritional demands increase.
-
Summer months, when heat stress and declining forage quality affect intake.
Without proper supplements, livestock may experience:
-
Poor weight gain or weight loss
-
Reduced fertility
-
Weakened immune function
-
Increased risk of diseases like grass tetany
Common Supplement Types
-
Minerals
-
Calcium, phosphorus, and salt: Basic needs for all livestock.
-
Magnesium: Crucial in spring to prevent grass tetany in cows on lush, fast-growing pastures.
-
Trace minerals: Zinc, copper, selenium, and others support growth, fertility, and immunity.
-
-
Protein Supplements
-
Important when hay or pasture is low in protein, especially in winter or drought conditions.
-
Examples: soybean meal, cottonseed meal, or commercial protein tubs.
-
-
Energy Supplements
-
Needed when animals are losing weight or during cold weather.
-
Examples: corn, oats, or molasses-based products.
-
Local Considerations for McDowell County
-
Soils in the region can be low in magnesium and selenium, so tailored mineral mixes are important.
-
Mountain pastures may have variable quality, so regular forage testing is key.
-
Variable weather patterns can lead to inconsistent forage growth—having a supplementation plan provides nutritional insurance.
Best Practices
-
Provide free-choice, loose mineral supplements specifically formulated for your livestock species.
-
Monitor body condition scores regularly and adjust feeding as needed.
-
Work with your local Cooperative Extension or veterinarian to analyze forage and choose the right supplement program.
