Is it always true
Do you know why they don't use feed -lot cattle ?
Is it because it is cheaper to use imported grassfed beef ?
Could it be that grass fed beef are difficult to sale because not marbled
with fat?
what happens to the pieces of meat from feed lot cattle that are not sold in
cuts. ( ground beef? animal foods?)

What do they use for animal food if they can't use beef byproducts? why
can't they?

does it mean that the marbled fats inserted between the muscles fibers have
a specially unbalanced ratio of omega 3 to omega 6, more than the
superficial fat layers betwen muscles and under skin.?
