What is NIR?
Near Infrared Reflectance Spectroscopy or NIR measures the absorbance of infra-red light by feed samples and is the most common tool used for routine analysis by laboratories today.
Estimating the concentration of dietary components by interpreting the pattern of infra-red absorbance is dependent on mathematical calibration equations. These equations are developed from a representative set of 60 or more samples and are specific to a feed or forage type, eg. grass silage.

What NIR equations are available?
Bioparametrics own and maintain calibration equations for grass silage, maize silage, wholecrop wheat, lupicaleage and hay/haylage. These include NIR equations to predict:
The carbohydrate degradation profile during IVGPT (ml)
The protein degradation profile during IVGPT (ml)
All other NIR calibration equations used by Bioparametrics are owned and maintained by the Forage Analysis and Assurance Group (FAAG), for which Bioparametrics is an active member
Can we develop equations for other feed or forage types?
If you have any specific requirement for NIR equations then we can provide you with equations to predict any proximate analyses and/or the degradation parameters described above providing that you can supply us with a minimum of 60 representative samples of your required feed or forage.
