ABSTRACT
Newborn calves were isolated from their dams before they were suckled and within 3 hr of birth were fed 1 liter of cow's milk containing either: a) no additives, b) 75.0 g gamma globulin, or c) 75.0 g gamma globulin and 2.0 mg histamine. Additional feedings were at 7 and 15 hr after the initial meal. Serum gamma globulin was determined before and at 1, 3, 5, 7, 11, 15, and 23 hours after the first feeding. Differences in serum gamma globulin between calves that received histamine-supplemented milk and gamma globulin and those that received only added protein in milk were insignificant. In all calves receiving gamma globulin, serum gamma globulin increased after the first two feedings, but the values plateaued thereafter. The gamma globulin in serum of calves fed only milk remained negligible.
