An experiment with a completely randomized block design and three treatments was performed: T1: control (no probiotic); T2: 10 of probiotic mL per animal; T3: 20 mL of probiotic per animal. The observations were processed by the analysis of variance. The results show no significant effect for these. Averages in the different treatments were as follows: initial weight T1 (8,06kg) - T3 (7,53kg); weekly food consumption T3 (9,77kg) - T1 (9,52kg); weekly weight T3 (40,77kg) - T1 (39,04kg); weight gain T1 (4,71kg) - T2 (4,61kg); T3 feed conversion (2,15 kg) -T1 (2,34kg). The incidence of diarrhea mainly showed up in T1 (57,14%), while in T2 and T3 was 28,57% and 14,28% respectively. None of the treatments showed mortality. The organ weight is within normal traits, It was not altered by the application of probiotic. Hematological indicators were within normal values. Benefit-cost treatments 1 and 3 obtained a return of $ 1,11. It is concluded that the animals experimented a better health condition with the application of probiotics. |
