Abstract

Immunological parameters showed no statistical difference (P>0,05) between treatments in any period, however after six days, T1 showed 41,07 x105 hemocytes/ml, coagulation of 34,40 s and 4,44x103 CFU/ml. Throughout the fourteen hemo-day period, T2 obtained the best values (55,76x105 CFU/ml). Af-cytes/ml, coagulation of 34,20 s and 15,4x103 ter 10 hours of inoculation, accumulated mortality presented fewer deaths in T1 and T3 (76,2%) at six days, whereas at 14 days was (93,2%) for T1. Weight gain and feed conver-sion presented statistical differences (P<0,05) only for the bioassay which lasted six days, where T2 showed a 54,3
