Lipotropic Factors for Beef cattle Fed High-Concentrate Diets1

Abstract

Total lipids and phospholipids of livers were assayed at intervals while feeding cattle high-concentrate, low-roughage diets comprised mainly of milo. Effects of treatment during the growing-finishing period with a group of lipotropic factors (LTF) (choline, m-inositol, folic acid and vitamin B12) or an "anti-lipotropic factor" (niacinamide)3 were evaluated in terms of liver lipids and carcass characteristics. Treatments were administered intraperitoneally or intraruminally at weekly or bi-weekly intervals throughout the growing-finishing period. Total lipid content of livers and phospholipid content of lipids (measured as lipid-phosphorus) were significantly affected (P<.05) by treatment with LTF. Both LTF and niacinamide tended to improve body weight gains, and LTF improved (P<.05) the carcass yield grade in the main experiment without significantly affecting carcass weights.
