Commodities

Practices

• Animal Production: grazing management, grazing - multispecies, grazing - rotational
• Education and Training: on-farm/ranch research

This project will evaluate whether virtual fencing technology can reduce labor demands and improve grazing efficiency compared to traditional portable electric net fencing on a small ruminant farm in Maine. Frequent rotational grazing is one of the most effective tools for improving pasture health, reducing parasite pressure, and increasing livestock performance. However, for many small farms (particularly those operating in remote or island environments) the labor required to install and move electric netting creates a significant barrier to implementing consistent, regenerative grazing practices.

The objective of this project is to compare virtual fencing and electric net fencing side-by-side over two full grazing seasons, measuring labor hours, rotation frequency, pasture utilization, and animal behavior. Goats and sheep will graze separate paddocks assigned to each fencing system, with detailed records kept on time spent setting boundaries, moving herds, addressing issues, and monitoring containment. Pasture use will be documented using forage height measurements and visual assessments before and after grazing events. Qualitative notes will capture animal adaptation, stress responses, and practical challenges or advantages encountered with each method.

The study aims to produce clear, farmer-focused data that can help livestock producers decide whether virtual fencing is a cost-effective and labor-saving tool for their grazing systems. Outreach will include a public field demonstration, online summaries, social media updates, and a freely accessible final report through SARE's project database. Results will also be shared with regional grazing groups and livestock networks to maximize impact and support the adoption of sustainable grazing practices in the Northeast.

The goal of this project is to evaluate whether virtual fencing technology can reduce labor requirements and improve grazing efficiency for small ruminants in a coastal island/rural environment. To support this assessment, soil and forage testing will be conducted to establish baseline pasture conditions and measure changes in forage quality across paddocks throughout the study. These tests are essential for understanding grazing efficiency, pasture utilization, and ecosystem impacts under each fencing system.

To answer the project's central question, virtual fencing and traditional electric net fencing will be tested side-by-side over two full grazing seasons. The objectives are structured to generate clear, measurable data and provide practical guidance for Northeast farmers considering the adoption of virtual fencing technology.

Objective 1: Quantify the labor required for each fencing system.

Measure and compare the total time spent on all fencing-related activities for each system, including:
• Boundary setup and adjustments
• Herd moves/rotations
• Troubleshooting or containment issues
• Battery/charger maintenance (for net fencing)
Results will be recorded using standardized logs documenting minutes per task, frequency of tasks, and weekly totals.

Objective 2: Compare grazing efficiency between virtual fencing and electric net fencing.

Evaluate the effectiveness of each system in supporting frequent, well-managed rotations by measuring:
• Rotation frequency under each fencing method
• Paddock size changes and flexibility
• Time animals spend grazing vs. waiting for moves
• Pasture utilization using forage height measurements before and after grazing
• Visual assessments of sward recovery after each rotation

Objective 3: Document small-ruminant behavior, adaptation, and welfare under virtual fencing.

Observe and record how goats and sheep respond to virtual boundaries, specifically tracking:
• Adaptation period (days until consistent boundary respect)
• Stress indicators or avoidance behaviors
• Instances of boundary testing or breaches
• Differences in movement, grazing pattern, or herd flow between systems
Qualitative notes and structured observation checklists will be used.

Objective 4: Evaluate the reliability and functionality of virtual fencing in a coastal/island environment.

Assess how the system performs under conditions unique to the Northeast, including:
• GPS coverage in forested or foggy areas
• Collar battery performance
• Alerts or system errors
• Boundary accuracy on mixed terrain or outer islands
• Practical challenges during small-boat access moves
This objective will document environmental limitations and equipment performance.

Objective 5: Identify the overall feasibility and cost-effectiveness of virtual fencing for small ruminant farms in the Northeast.

At the end of the study, integrate all measured data to determine whether virtual fencing:
• Reduces labor enough to justify its cost
• Provides ecological benefits through more frequent rotations
• Reduces long-term fencing equipment expenses
• Offers an operational advantage to small farms, including those in remote or island settings

Objective 6: Soil and Forage Monitoring.

Assess baseline soil health and forage quality across all study paddocks and track changes throughout the grazing seasons under both virtual fencing and traditional net fencing systems. This objective will use standardized soil tests and forage analyses to measure organic matter, nutrient levels, and forage density. Results will help determine whether improved rotation enabled by virtual fencing supports measurable gains in pasture productivity, soil quality, and resource conservation.
