However, a “coarse grain mix” is usually only for poultry (chickens). If the animals being fed are calves, it is a “coarse calf mix”. If the animals are horses or sheep, it is a “coarse mix” and if the animals are pigs, it is a “coarse pig mix”.

So, if you just wanted to use one term for all species of livestock, I think that you could simply say, "coarse mix" or "coarse feed mix".

So, an appropriate translation of, “χονδροειδές και συμπυκνωμένο φύραμα”, would be, “a concentrated coarse mix”. See:
