Review your Loss on Drying results for Accuracy

If you’ve ever had doubts about the moisture results for your feeds then this study should give you some insight at what is actually happening.  The study examines the various methods used in determining moisture content in feeds.  The contention is that the empirical methods of feed estimation – evaporation and loss on drying – ‘differ greatly in effectiveness’. This, according to the author, results in bias that further impacts the ‘accurate quantification and expression of other nutrient values’.  The paper then goes on to compare the different methods for a range of feeds, suggests an appropriate reference method, and concludes by making general recommendations on best practices to improve moisture testing results.
