Tall fescue, a common pasture grass, can harbor a hidden danger: toxic endophytes. These fungal partners, while beneficial for the plant, produce toxins that harm grazing animals. But fear not, farmers! Effective management strategies can minimize the impact of fescue toxicosis and keep your livestock thriving.
Know your enemy: First, assess your pastures. Test for endophyte levels to determine the severity of the threat. Based on the results, you can choose the best approach.
Replacement options: For high infection levels, consider replacing the stand with novel endophyte varieties, free from the harmful toxins. Spray-Wait-Spray or Spray-Smother-Spray methods offer effective solutions.
Existing stand management: If replacement isn't feasible, smart management practices can still improve your pastures. Here are some key tactics:
- Dilution: Introduce non-toxic forages like red clover or crabgrass to dilute the toxins and offer healthier options for your animals.
- Bioactive compounds: Red clover, with its unique compounds, can counteract the effects of fescue toxins, improving animal health and performance.
- Strategic avoidance: During peak toxin periods, like summer or late fall, consider alternative grazing options to minimize exposure.
- Clipping seedheads: Seedheads concentrate toxins. Clipping them reduces ergovaline levels and maintains forage quality.
- Supplementation: Energy and protein supplements can partially alleviate the effects of fescue toxicosis, especially during critical times.
Remember, fescue toxicosis is a manageable challenge. By implementing these strategies, you can create safer pastures and unlock the full potential of your livestock. Don't let tall fescue hold you back – take control and watch your animals flourish!
