Interpretive Summary:

Technical Abstract: Effects of dietary vitamin A (VA) and E (VE) on performance and scour incidence of milk replacer-fed Holstein bull calves were examined. One hundred forty-four calves were purchased (34 hr transit) and assigned according to body weight (initial, 42.9 kg) and blood gamma globulin concentration. Calves were fed milk replacer (22% protein, 20% fat) containing 2000 (NRC), 4000 or 34,000 IU of VA/d and either 20 or 100 IU of VE/d. Calves were individually housed in crates and fed 2 times daily at 0700 and 1615 hr. Weight gains, daily scour score, scour duration and electrolyte/medication costs were calculated weekly and for the 4-wk trial. These data indicate that VA and VE had no effect (P more than .05) on calf performance or scouring.
