Each type of fencing can be optimized for a variety of scenarios influencing factors such as visibility, conductivity, strength, and ease of setup. Choosing the correct type of portable electric fence depends on the specifics of the grazing area, the type of livestock being contained, and the individual needs of the farm or grazing operation.
Planning Your Temporary Grazing Area
Effective management of temporary grazing areas increases forage yields and supports livestock health. In planning these areas, it is pivotal to understand your pasture's specific needs, create a detailed base map, decide on the size and shape of the paddocks, and craft a strategic water system plan.
Assessing Pasture Needs
To efficiently use a portable electric fence kit, assess the forage needs of your pasture. This includes considering the type of livestock and their grazing behavior. For cattle, measure the daily intake of forage per head and calculate the necessary acreage to meet this demand without overgrazing.
Creating a Base Farm Map
Mapping your farm is crucial for strategic placement of paddocks. Utilize GIS tools or hand-draw your farm to scale, marking permanent features like trees, water sources, and existing fences. This base farm map should also identify soil types and grass species to ensure appropriate grazing management.
Determining the Size and Shape of Paddocks
When deciding on paddock size, factor in daily pasture moves for rotational grazing. The shape of temporary paddocks should allow livestock to graze uniformly and should consider the natural landscape to maximize grass usage and avoid soil erosion.
Livestock Type
Cattle
Sheep
Daily Forage Needs (lbs)
20-30 per cow (Cattle)
3-5 per sheep (Sheep)
Paddock Size (acres)
0.5-2.0 (Cattle)
0.1-0.5 (Sheep)
Water System Planning
A reliable livestock water system must be accessible within temporary paddocks. Options include portable troughs or a network of pipes connecting to a central water source. Ensure the system provides ample water and supports daily pasture moves without excessive labor.
By focusing on these essentials, you can create a grazing strategy that maximizes pasture utilization and supports your livestock's health and productivity.
Setting Up the Portable Electric Fence
Installing a portable electric fence involves careful planning and precise execution. One must ensure the selected location suits the livestock's needs and the fence components are appropriately laid out for optimal functionality.
Selecting the Right Location
The ideal location for a temporary electric fence is on level ground with minimal vegetation that could interfere with the electric current. It should provide ample grazing space and be easily accessible for moving livestock. Considerations should include proximity to water sources and shelter, as well as the area's soil conductivity which plays a role in grounding efficiency.
Laying Out the Fence Components
Start by delineating the perimeter of the grazing area. Roll out the poly wire or tape to measure and plan the layout, keeping in mind the need for gates and access points. Ensure that all components—such as posts, wires, and connectors—are accounted for before installation begins. Clear any debris or vegetation that may hinder the installation or reduce the voltage of the electric current.
Installing Posts and Wires
With the perimeter marked, install posts at regular intervals—closer together on curves and corners for stability. Standard distances range up to 50 feet, but more posts may be required in uneven terrain. Thread the poly wire through insulators on the posts, maintaining a consistent height that corresponds with the animal’s shoulder level. The wire should be taut to provide an effective barrier but with enough give to withstand animal pressure without breaking.
Connecting the Energizer and Grounding System
The electric fence energizer, which powers the fence, should be connected to the poly wire using proper connectors and insulated lead-out cable. It's responsible for sending pulses of electricity through the hot wire. Connect the energizer to ground rods driven at least six feet into the earth to complete the circuit. The number of ground rods may vary depending on soil conditions and energizer specifications, but a minimum of three is standard for effective grounding. Test the voltage of the fence using a voltmeter to ensure it is operating at the desired level for containing livestock.
Grazing Management Techniques
In the context of grazing management, implementing a carefully planned rotational grazing program using a portable electric fence kit is crucial. This system not only ensures the health and productivity of the grasslands but also aligns with animal health requirements.
Implementing Rotational Grazing
Rotational grazing involves moving livestock between pasture subdivisions, which allows grasslands recovery and regrowth intervals. An effective rotational grazing strategy typically includes daily grazing slices, ensuring that each section of the pasture is grazed and rested in a controlled sequence. This kind of grazing rotation maximizes forage utilization and can dramatically enhance pasture life and yield.
Adjusting for Seasonal Changes
Seasonal changes influence the growing season, necessitating adjustments in the grazing plan. For example, during the peak growing season, the rotation speed through paddocks might quicken to match the fast regrowth of forages. In contrast, during slower growth seasons adjustments might include enlarging the allocated area or reducing the stock density to allow adequate forage for livestock without overgrazing.
Managing Forage and Grass Growth
For sustainable pasture management, particularly in grass-finishing operations, it's essential to evaluate and manage forage growth effectively. Observing the grass length and density can dictate when to move livestock to new grazing slices. Criteria for such decisions should include the height of the grass - typically moving livestock on when the grass has reached a certain height and stopping grazing when it reaches a certain minimum height to avoid overgrazing and to allow for recovery.
