Abstract
The study include assessing efficient of the bioextract of the B. subtillis of the protection of the nestling from the toxic effect of aflatoxine that produced by A. flavus And the result showed the ability of the bioextract of B. subitillis on the radical growth inhibition of A. flavus that produce and non-produce aflatoxine ,on the culture media P.D.A. (Ratio of inhibition was 100%) when it used at concentration 2gmL and the result showed the safety of the small intestine tissue and liver from any damage , in compare with control treatment by which the nestling feed on a blackberry that non treated by the bioextract of this bacteria . and the positive effect refluxed on the nestling growth by increase weight normally to be approximately 505gm through 3 weeks from hatching ,without signification differences from the control treatment which was 531 gm in the same time , while ,the rate of the nestling weight that treated by blackberry that infected by the toxogenic fungi was 382,5 gm in the same time . this resultant from the infected of the intestine and the liver of the nestling in the last treated ,by disease syndromes . Histological study of the liver and small intestine sections appear aggregation of inflammatory cells with presence of vascular conduction in the liver cells. And lyses of the epithelial layer of the small intestine and skim off some of the microvillus of the small intestine .
