^aTurkey poults were treated with CsA, 100mg per kg body weight, at every third day as indicated.

^bTurkey poults were treated with CY, 5mg per turkey poult per day on the first 3 days post-hatching.

^cTurkey poults were intramuscularly injected with SRBC at 10 days of age. Antibody titers to SRBC were determined by hemagglutination at 7 days after injection.

^dLymphocyte proliferation responses to Con A.

^eTurkey poults were infected with TCV at 10 days of age.

^fBody weight (BW) gain was determined from 10 (prior to infection) to 19 days of age.

^gIFA for TCV antigen in the intestine.
