AFIA – Laboratory Methods Manual
This is version 8 of the reference manual of the standard methods for the analysis of fodder. 
This manual is the result of extensive discussion and collaboration among fodder testing laboratories, animal nutritionists and representatives of the Australian fodder industry.  Its objective is to foster uniform testing methods across Australian laboratories for the quality criteria of importance to the fodder industry.

The quality attributes of hay and silage vary greatly compared to other commodities such as grain. Consequently, the objective measurement of fodder quality is critical when seeking predictors of livestock performance.
