Resumo: | Beauveria bassiana, an important insect pathogen was used to evaluate its effect on the feeding, behavior, histology of the digestory system and anatomy of Gallus domesticus. The fungus (strain Unioeste 4) was administrated orally treated with chicken food. Chicken feces were collected, and the birds observed for 28 days. Also, were evaluated the weight of the birds, as well as any sign of intoxication or pathological modification. Tissue samples were withdrawn to test lesions with the optic microscope. There was 100% of survival of the birds, and no behavior alteration or external lesion was found. The test group presented the highest weight gain (1383.9±54.4g). Viable conidia were observed in the feces until 24 h after feeding the fungus, indicating that there was no germination inside the digestory system. No tissue lesion was observed, providing overwhelming evidence for the safety of B. bassiana to non-target organism G. domesticus.
