Abstract
SUMMARY The aim of this study was to evaluate the effects of additional consumption of immuneglobulins associated with high quality colostrum in health and performance of dairy calves. After birth, 80 females were randomly assigned to two treatments: MC) high quality colostrum, supplied in a volume corresponding to 15% of birth weight; and MC+S) high quality colostrum (15% of birth weight) + colostrum supplement. Blood parameters were not affected by the additional supply of immune globulins (Ig) by colostrum supplement feeding. The concentrate and total dry matter intakes were not affected by the administration of colostrum supplementation. The additional intake of Ig through the colostrum supplement did not affect the performance or feed efficiency of calves; however, animals doubled their birth weight at the end of the period, as occurred with MC fed calves. Regarding the health, additional supply of Ig did not affect the number of days with diarrhea, days with fever or medicated days. The additional intake of Ig via colostrum supplement in combination with high quality maternal colostrum have not improved immunity or affected the performance and health of dairy calves.
