Fibre needs to be determined in novel products to ensure balanced ruminant rations. It is important to understand the difference between the two methods when the analysis of an alternative feed ingredient is being considered. Wet chemistry is the preferred method for analysis of non-traditional feedstuffs, because it more accurately measures the nutrient content. Analytical procedures are standardized for each nutrient test. Measures the nutrient content, does not predict it.
Analytical procedures are the same regardless of the sample being tested.
Easy to check for errors. Repeat analysis can be done on only the result that is out of line. Cost can be twice that of NIR tests. Turnaround time for analysis may be up to 1 week. However, some labs offer 24- hour turnaround to compete with NIR analysis.
