Cholesterol, Hemoglobin, and Mineral Composition from Nonruminating Holstein Bull Calves as Affected by a Milk Replacer Diet in High Phosphorus and Alpha-Tocopherol Supplement,

Abstract An experiment was conducted to study the effect of dietary to copherol and P on the serum cholesterol, muscle cholesterol, serum vitamin E, and mineral composition of nonruminating calves. A milk replacer diet was supplemented with a high monosodium phosphate (18 g· calf −1 ·d −1 ) and vitamin E (as coated dl-alpha-tocopheryl acetate 100 IU· calf −1 ·d −1 ) and was fed to Holstein bull calves (n = 15) for 2 wk prior to slaughter. This significantly decreased serum and muscle cholesterol; increased vitamin E, P, Ca in serum; and simultaneously reduced serum Na content 15% when compared with that of the control group (n = 15). There were no treatment effects on serum K, Mg, packed cell volume, and hemoglobin values. These findings may be beneficial in regulating the incidence of coronary heart disease if dietary tocopherol and P could cause the same effect in humans.
