In finishing studies at several universities, cattle performance was similar whether liquid or dry supplements of equal composition were fed.
Liquid supplements are popular in some feedlots because they are easy to blend in a complete ration and assist in bunk management. The addition of a liquid supplement or molasses to a ration reduces dust and fines, improving the texture and condition of the ration. Molasses can also mask the flavor of urea and add energy to the ration.
There can be differences in the amount of water in liquid supplements -- typically 25 to 35 percent -- in which the same levels of protein equivalents, minerals and additives are guaranteed. If water is added to liquid supplement, it will have a lower energy value. Molasses alone will not supply sufficient energy at the level and time needed to get maximum utilization of urea. Therefore, other sources of energy such as grain are required to best utilize supplements with a high urea content. Research indicates that beef cows and stockers grazing low-quality forages make poor use of urea in liquid or dry supplements.
