Application of different disinfection solutions significantly
(P < 0.001) affected total aerobic mesophilic
bacteria values (Table 3). Surface flora of hatching
eggs decreased (P < 0.001) with the increased propolis
concentration. The microbial count at incubation
periods of 1 d decreased from 5.35 to 2.21 log cfu/egg
within the P15 propolis treatment.
