VOL. 70 (4), 961-999, 2004 VANADIUM - AN ELEMENT BOTH ESSENTIAL AND TOXIC

The vanadium-deficiency goats produced normal milk, in normal
amounts and with normal milk fat contents (8, 7, 20).

Several blood parameters were estimated with the usual methods
(Table 18). Of these, only the concentrations of creatinine and trigly-
cerides and the activity of ?-glutamyl transferase were significantly
higher in vanadium-deficient compared to control animals (52).
