Corn Stalk Grazing Calculator
Here’s a comprehensive table summarizing the key points about corn stalk grazing:
| Aspect | Details |
|---|---|
| Benefits | – Lower feed costs (potential savings over $1/day/cow)4 |
| – Improved nutrient recycling in soil2 | |
| – Delayed feeding of hay | |
| – Minimal impact on subsequent crop yields14 | |
| – Reduced volunteer corn in following year’s crop2 | |
| Best Practices | – Introduce cattle slowly to avoid grain overload3 |
| – Implement strip grazing for efficient forage use24 | |
| – Limit access to 3-4 days of feed at a time3 | |
| – Provide supplemental fiber (low-quality hay or straw)3 | |
| – Start grazing soon after harvest for best nutritional value2 | |
| Stocking Rate | – Based on corn yield: e.g., 1.4 AUM/acre for 150 bu/acre corn1 |
| – Aim for 50% utilization of leaf and husk5 | |
| Nutritional Value | – Cattle select in order: grain, husks, leaves, cobs, stalks4 |
| – Sufficient for dry cows and mid-gestation cows5 | |
| – May need supplementation for lactating cows or heifers5 | |
| Considerations | – Monitor soil compaction, especially on dryland fields45 |
| – Conduct feed tests for nutrient content and mycotoxins3 | |
| – Have a backup plan in case of adverse weather3 | |
| – Consider corn variety and planting strategy for grazing3 |
