Abstract

Six 9-month-old female Dutch Friesian cattle were given hay and pelleted concentrates with added 130 g CaCO3 or 100 g Na2HPO4 daily for periods of 50 days each. The supplements did not significantly influence growth or vitamin A, Cu or Mn in liver or blood plasma, although more P tended to retard growth. Liver vitamin A, Cu and Mn generally decreased significantly with time. Cu was more closely related to growth than vitamin A or Mn. A fall of Cu in blood plasma and liver was associated with a fall in the vitamin A in liver and with an increase of vitamin A in plasma.-V. J. B.
