Tails tell the truth

"Tail hair tells tale of cattle’s diet," says a PhysOrg.com article:
Tail hair can show if cattle have been grass-fed or not, according to scientists. By chemically analysing the tail hair, it is also possible for scientists to tell if, and when, a grass diet has been substituted for other types of feed over the past 12 months....
Following the analysis, the scientists can almost identify the precise day when the grass diet of the animal may have been substituted with cereal or concentrate. 
According to the scientists, omega 3 fatty acids are significantly higher in grass-fed beef than they are in cereal-fed beef.  As a result, beef from grass-fed cattle is often labelled and marketed on the basis of having high levels of omega 3 fatty acids and CLA (which together have been linked to several health benefits in humans). 
That is, feeding cattle the food Jah intended them to eat produces easily discernible effects such as healthier cattle and more nutritious food. Strange world we live in that everything should mesh just so.
