A method of forming a low moisture block with cold flow resistance proceeds by subjecting a feed mixture containing molasses-like liquids to mixing to form a homogenous mixture; dehydrating the molasses-like mixture to less than about 2.0% moisture using heating; adding to the dehydrated molasses-like liquid mixture one or more feed ingredients in dry ingredient form, comprising 10% to 50% by weight of the resulting mixture; and adding to the dehydrated molasses-like mixture a composition comprising CaO or reactive MgO or combinations thereof, with the composition comprising 0.1% to 10% by weight of the resulting mixture. The composition is mixed in to form a homogenous mixture.
