The second factor was the duration of no feeding for 10 and 5 days. The third factor was the amount of feed given during recovery period, thatwas 50% andn 25% of the normal consumption. So, the total of the treatment of forced molting program applied were 9 treatments. The data obtained were analysed using analysis of variance (ANOVA), orthogonal contrast test. The result showed that stress could decrease the level of antibody, percentage of lymphocyte and leukocyte value significantly (P<0.05) compared to the control group, but the decline is temporary, because after stop fasting, the number of those cells will return to normal (reversible.
