Energy use is one of the major inputs to both intensive and extensive pig systems
Energy use in pig production
Energy use is accounted for by heating, ventilation, feed production and distribution, and slurry storage. Energy efficiency is important in the control of emissions to the atmosphere. Improvements in insulation, automation techniques and general building performance can greatly improve energy efficiency with attendant improvements in pig production and welfare.
Energy use can be minimised and costs reduced through sensible selection of system components, wise use of insulation, and attention to design and operation of control systems.
High priority / low cost measures
- Monitor energy use – this is the basis of good energy management
- Carry out maintenance and repairs – an essential aspect to reduce wasted energy
- Check the accuracy of your controls – temperature sensors should be regularly tested
- Use information from the control system for performance management
Medium and long term measures
- Improve building insulation
- Use enclosed creeps- open creeps experience substantial heat losses
- Improve controls – good controls are a prerequisite for maintaining the right temperature and minimising the use of energy
- Efficient lighting systems
- Use high efficiency motors and variable speed drive motors on feed and waste handling systems
