Meta-Analysis: Efficiency of Proactive Uterine Health & Fertility Protocol in U.S. Dairy Farms
Uterine health plays a vital role in the reproductive success and overall productivity of dairy cows. Postpartum complications such as metritis and retained placenta are common and costly, often leading to reduced fertility, lower milk yields, and increased veterinary expenses. A recent meta-analysis conducted across eight large-scale farms in the western United States evaluated the impact of AHV’s proactive Uterine Health & Fertility protocol on dairy cow performance compared to conventional strategies.
Trial Overview
The study involved 4,495 cows randomly selected based on calving week, with cows calving in odd weeks receiving the AHV protocol and those in even weeks serving as controls. The AHV group was treated with AHV Metri Bolus, AHV Aspi Bolus, and AHV Milk Start Paste. Control cows in their second or higher lactation received a commercial oral calcium supplement. The farms ranged in size from 1,000 to 20,000 cows, totaling 45,000 cows across all locations.
Key findings:
The results demonstrated significant improvements in health and productivity among cows treated with the AHV protocol:
• Metritis Incidence: Reduced by 34% (4.6% vs. 7.0%)
• Retained Placenta Incidence: Reduced by 71% (0.4% vs. 1.4%)
• Milk Production: Increased by 3 kg/head/day during the first 100 days in milk (DIM)
• First Service Conception Rate: Improved by 1.9% (48.4% vs. 47.5%)
These outcomes highlight the effectiveness of a proactive approach in minimizing postpartum complications and enhancing reproductive performance.
Lactation Group Insights
The protocol showed particularly strong results in cows with three or more lactations, where metritis incidence dropped from 12.3% in the control group to 5.1% in the AHV group. Similarly, retained placenta incidence in this group fell from 3.0% to 0.9%. These findings suggest that older cows may benefit most from proactive uterine health management.

Financial Impact
The economic analysis revealed a substantial return on investment. The protocol led to savings of nearly $500,000, factoring in reduced treatment costs, improved milk yield, and enhanced fertility. After accounting for the cost of the protocol ($184,295), the net gain was $111.17 per cow.
Conclusion
This meta-analysis confirms that AHV’s proactive Uterine Health & Fertility protocol offers a highly effective and economically viable solution for improving postpartum outcomes in dairy cows. By reducing the incidence of uterine diseases and boosting milk production and fertility, the protocol supports both animal welfare and farm profitability. As the dairy industry continues to evolve, embracing preventative strategies like AHV’s protocol will be key to sustainable and ethical herd management.
