Quality The UK Forage Analysis Assurance Group is the quality control governing body for laboratories analysing forages.
AnalysisCollectively the group analyses approximately 70,000 grass, maize and whole crop cereal silages every year.
InfraredOur members use Near InfraRed Reflectance Spectroscopy (NIRS) machines to rapidly, reliably and accurately measure silage composition.

FAA’s “Quality Control” role over forage laboratories
improves accuracy, efficiency and reliability of silage analysis

As a result of FAA’s work the accuracy of forage analysis is constantly improving and the variability reducing, making the information on which feeding decisions are based more reliable. In turn this helps to reduce inefficiencies in all aspects of the agri-food supply chain.

Formed in 2000, the group is made up of laboratories that collectively test around 70,000 samples a year which is the vast majority of silages analysed in the UK. The FAA group is self-funded and run by an independent body,  AIC Services (Agricultural Industries Confederation Services) by chairman John Kelley and technical secretary Roberta Reeve.

The FAA was set-up by our members because analysing wet forage by NIRS can be fraught with difficulties due to the nature of the material being tested, the differences between instruments and the personnel who process the samples.

Group members take part in a Proficiency Test which measures performance against results from wet chemistry analyses, which are the gold standard. This gives customers confidence that laboratory results are accurate and confidence in the data produced and how it is used in developing feeding programs for livestock.

The group aims to continually improve the services available to their customers, including developments in techniques and technology ensuring that the quality of analysis is maintained.
