The energizer must deliver sufficient shock in proportion to the requirements placed on it. The power output should be selected based on the following calculations. Location of electric fence energizer (access to A/C power), type of animals, length of the above-ground or underground electric fence, number for strands of wire, conductivity of wire, vegetation present on the fence and soil conditions for grounding.

There are 3 components to a Tru-Test scale system – A high quality Tru-Test cattle and livestock scale system will help you collect and analyze data, making your farm and ranch business better at making livestock management and business decisions.

Scale Indicators 
Its the brains of a livestock weighing system. The indicator receives the weight from the load bars and displays it on screen. Some trutest models also store weights and animal IDs.

Load Bars
Load bars do the heavy work. When an animal steps into the chute or on the platform, they lock on to the weight, even as the animal is moving.

Weighing Platforms
Platforms are used in portable installations and are durable to support the weight of an animal but light enough to be easily moved.

Sustainable agriculture is a philosophy or an adopted attitude usually characterized by the intention to farm holistically, support and enhance communities and the local environment, and maintain continuous improvement and equity. In practice, it employs diverse farming practices that balance three main factors interchangeably without compromising the others: economic viability, environmental soundness and social responsibility. Sustainable farming is about longevity. It attempts to achieve the best possible agricultural result over the longest period of time.

Key Concepts

• Balance — maintaining an equilibrium between inputs and outputs surrounding economic conditions, environmental factors, and social consciousness.

• Continuous Improvement — providing crop yields while decreasing inputs necessary for future harvests, striving for zero soil loss and setting annual goals for improving quality.

• Diversity — fostering strength and resiliency through differentiation. Physical: various types of farms & locations Human: different races, ethnicities, and background of farmers Biodiversity: crop and livestock varieties Market: range of venues for sale and products

• Equity — providing workers with fair treatment and a healthy environment. Livestock are also treated humanely and raised in natural environments.

• Conservation — ensuring that resources such as land, water and soil taken from the land are put back into the ecosystem and available for future generations. Composting, for example, enhances soil quality by adding organic matter to the soil after an agricultural process has removed soil nutrients.

Energizers that are low impedance energizers have the ability to regulate their output and maintain a constant voltage supply to the fence even as the grounding and fence conditions deteriorate as well as increased vegetation contact. This means as more vegetation draws amperage from the electric fence (short circuiting or grounding the fence), a low impedance energizer will produce more energy or joules to overcome this loss due to plants while maintaining adequate levels for animal control.
