Determination of the Metabolizable Energy and Feeding Value of a Lignin Sulfonate Pellet Binder

Abstract

THE increased use of pelleted feeds has prompted feed manufacturers to become vitally interested in efficiency of pelleting and pellet durability. To increase the durability of pellets, manufacturers have used various types of pellet binders, methods of conditioning, and different sizes of dies. Collodial binders, molasses, and fats have been used for many years and their effect on pellet durability and pelleting efficiency has been reported (Young and Pfost, 1962; Blakely et al., 1955). Most recently lignin pellet binders have been used to increase pellet durability (Pfost, 1962, 1964). The material used as a binder may or may not add nutritive value to the diet. Molasses and fats serve as sources of energy in the diet. Camp (1959) reported that soft phosphate may be used as a pellet binder and to supply part of the phosphorus requirements in poultry rations. The bentonite type of binders would supply little nutritive value. . . .
