In the absence of an agreed national standard for the definition of grass fed, Overseer uses the terms of the draft AsureQuality Grass-Fed Standard to enable the definitions and sets a minimum criteria for feed management practices for the farming of bovine animals for dairy production.
The term “grass-fed” has a connotation of animals with daily access to pasture year-round; the standard promotes this whilst recognising that animal welfare is a priority and consideration must be given to environmental factors.
Every effort has been made to ensure that the terms of the standard are well represented within the software. Further information about the standard, and its implementation into Overseer can be found here. Queries about the standard, and certification options should be addressed to AsureQuality.
