Calves were given, during at least the first 30 days of life, one of the following treatments: (A) whole milk, colostrum and milk replacer (1:1:2); (B) whole milk; and (C) milk replacer. Although without statistical significance, calves fed milk replacer had a tendency of earlier and more severe diarrhea. The duration in treatment A did not differ from B, but was significantly shorter than C. These observations could be a consequence of the lack of active immunoglobulins in the treatment C diet, resulting in less protection in the digestive tract. The study of correlations suggested that higher levels of immunoglobulins delayed the occurrence of diarrhea and that the sooner it occurred, the stronger was the tendency to show longer duration, thus affecting weight gain.
