An improved, continuous process for the production of animal feed supplements including an apparatus for carrying out such process is provided. Broadly, the process includes continuous preparation of a preblend including molasses and vegetable fat, followed by continuous cooking of the preblend in an elongated cooking zone and batch cooking assembly. The cooked preblend is then continuously treated for removal of moisture and partial cooling thereof, whereupon dry ingredients (e.g., vitamins and protein sources) are added and the resultant feed supplement is continuously cooled and packaged.
