Abstract

 

The parasporal crystal proteins (Cry) of Bacillus thuringiensis (Bt) strain BT6, which was isolated from Sika Deer faeces, exhibited a similar effect with diclazuril for controlling the infection with Eimeria tenella in chickens. A far more considerable body weight gain was found in the chickens treated with BT6 Cry proteins, as compared to chemical drug-treated groups, infected-untreated groups and even the uninfected group. This work is a preliminary contribution aiming to develop Bt Cry proteins for fighting coccidiosis in chickens.

 

Key words: Bacillus thuringiensis, faeces, parasporal crystal proteins, coccidiostatic,Eimeria tenella, chicken.
