AP-5 helps cattle handle toxic fescue by targeting ergovaline through binding, deactivation, and circulation support. By addressing the toxin and its vascular effects, AP-5 supports heat tolerance, intake, breeding performance, and calf growth.
Helps cattle better handle summer heat caused by fescue-related vascular stress.
Supports reproductive performance where ergovaline exposure can reduce conception.
Supports cow condition, milk production, and calf weaning weight under fescue pressure.
Field data shows AP-5 supports cattle on toxic fescue by helping improve body temperature, breeding performance, calf weaning weight, and return on investment.
AP-5 heifers showed a 1.4°F lower rectal temperature compared with controls in the Angus heifer breeding and temperature trial.
The AP-5 group reported a 15% higher first-service A.I. conception rate than the control group.
Missouri cow/calf farm trials reported an average 63 lb improvement in calf weaning weight for AP-5 groups.
AP-5 trial materials report an estimated 19:1 return on investment based on calf and cow value.
Discover AP-5
AP-5 is a proven feed additive approach built for commercial cattle operations grazing toxic tall fescue.
If you manage beef cattle on tall fescue, fescue toxicosis can quietly cost you every grazing season through heat intolerance, lower conception rates, lighter calves, rough hair coats, and higher maintenance costs.
AP-5 helps cattle handle the effects of toxic fescue by targeting ergovaline through binding, deactivation, and circulation support — helping protect heat tolerance, breeding performance, calf growth, and herd profitability.
AP-5 helps cattle handle the effects of toxic fescue by targeting ergovaline through binding, deactivation, and circulation support.
Ergovaline from toxic tall fescue can restrict circulation and contribute to heat intolerance, lower conception rates, lighter calves, and reduced performance. AP-5 is designed to address the toxin and its vascular effects at multiple points.
AP-5 Profitability
Toxic tall fescue creates a biological bottleneck: ergovaline restricts circulation, cattle run hotter, intake and reproduction suffer, and calves wean lighter. Over time, those losses compound across the entire cow herd.
AP-5 helps address the problem through a multi-pathway approach: binding, enzymatic deactivation, and circulation support. That means AP-5 is not just treating symptoms — it is designed to help cattle perform better while staying on existing fescue-based programs.
Toxic fescue costs producers through lighter calves, lower conception rates, heat stress, and higher cow maintenance. AP-5 is built to help protect performance without the cost and disruption of pasture renovation.
AP-5 materials report an annual cost of about $10.50 per cow per year.
Trial materials report an estimated 19:1 ROI based on calf and cow value.
Missouri cow/calf trials reported AP-5 groups averaged 63 lb heavier calves at weaning.
The AP-5 cow/calf trial summary reported 5% more bred cows after 60 days.
AP-5 is designed to help cattle perform on toxic tall fescue by addressing ergovaline exposure, supporting circulation, and protecting the outcomes that drive cow/calf profitability.
Ergovaline can restrict blood flow, increase heat stress pressure, reduce reproductive efficiency, and contribute to lighter calves at weaning.
Cattle consume endophyte-infected tall fescue containing ergovaline.
Ergovaline acts as a vasoconstrictor, restricting circulation and increasing performance stress.
AP-5 combines binding, enzymatic deactivation, and vasodilation support to address the toxin and its effects.
Approximate annual cost per cow reported in AP-5 materials.
Visible herd response reported in AP-5 source materials.
Customer retention basis reported in AP-5 partner materials.
Use AP-5 when fescue pressure is affecting cattle comfort, breeding performance, calf growth, or overall herd condition.
Toxic tall fescue can quietly reduce performance through heat intolerance, lower conception rates, lighter calves, poor shedding, and higher maintenance cost. AP-5 is designed to help cattle handle those challenges through binding, deactivation, and circulation support.
Use during fescue grazing, with added focus during breeding season and late gestation to support conception, cow condition, and calf performance.
Adjust based on forage conditions, ergovaline pressure, and performance goals to support intake, gain, and thermoregulation.
Prioritize during development and first breeding to support reproductive performance under fescue pressure.
AP-5 field data connects toxic fescue support to measurable improvements in body temperature, conception rate, calf weaning weight, cow condition, and herd-level performance.
In a fescue pasture trial, AP-5 heifers showed a lower rectal temperature and stronger first-service A.I. conception performance compared with controls.
Across three Missouri farms, cows were split into control and AP-5 groups. AP-5 groups showed measurable improvements in cow weight, calf weaning weight, and bred cow percentage after 60 days.
Combined producer records from Missouri, Arkansas, Iowa, and Oklahoma reported herd-level performance across cattle fed AP-5 or 454 Spice Mix in mineral or tubs.
