Are you into cattle feed manufacturing or for your own dairy farm consumption.
Damaged grains are mostly sold by FCI through tenders.
If you buy from distance locations through traders the transportation cost . will be more than feedstock itself.
TMR feed concept is an old one being practiced in large farms across U.S. and some other foreign countries. Total mixed ration ( TMR ) can also be used for small ruminants like goats .
You can make TMR locally available ingredients
Thanks for your information, you are right , but I am expecting some contacts near by area like beer manufacturers or some other sources where I can get cheap grain for my dairy farm.
