Measured improvements in reproduction and calf weaning weight under fescue conditions
Commercial cow/calf observations from a three-farm Missouri trial evaluating AP-5 under fescue toxicosis conditions. Based on control vs AP-5 mineral comparisons measuring cow weight change, reproductive performance, and calf weaning weights.
Annual Cost
Approximate cost per cow per year
Weaning Gain
Average increase in calf weaning weight across all farms
Bred Cows
Improvement in cows bred within 60 days
Cow Performance
Bodyweight improvement observed across all AP-5 groups (+32-86lbs)

AP-5 demonstrated consistent improvements in cow performance, reproduction, and calf weaning weights across all three farms.
Across all three farms, AP-5 consistently improved cow body condition, reproductive performance, and calf weaning weights.
Control groups showed either weight loss or reduced gains, while AP-5 groups demonstrated consistent improvement across all measured categories.
AP-5 costs approximately $10.50 per cow per year and has demonstrated a reported 19:1 return on investment based on calf and cow value assumptions.
AP-5 improved both reproductive performance and calf weaning weights across multiple farms under real-world fescue conditions.
