Truth be told, for concentrates there is a good correlation between the less expensive and quicker ether extract analysis compared with total fatty acid concentration, thus making it particularly useful for monitoring variability of batches of byproducts. This does not hold true for forages since often fatty acids are only 50% of ether extract in that case.
The Bottom Line:
Stick to using ether extract for byproducts, rather than forages, as a measure of fatty acid concentration and consider it a simple, inexpensive tool to monitor variability of these feedstuffs.
