Résumé
Evaluation of broiler diets based on mycological and chemical examination : Thirty broiler feed samples collected from feed bags and Seeders (1 6 starter and 14 hislier diets) were examined. The following results were reported : 1- The incidence of Siulgi in Seed was 98.3%, The incidelice of iimgal co itauination was higher in samples collected Sron Sceder ( 100%) llian from Seed bags (96.6%). According to their fungal load 86.6% of the examined sainples were jtdgcd as spoiled, 10% as reduced fieslums as 3.3 only as fresh Seed. 2- The avc a(b 1-1 tmtcnts of Moisture, Cnldc protcin, crude Sat and ash in different starter broiler diets were 14.05% - 20.73 - 2.74% ml7.53 respectively. A11 the tested fuigi in different levels between lo3 to 10S/g. Ihe prevalence of rimgal conknination including 13etlicillircnt s. yeast, lirrsa itint sp., A. jluvas. A. ttigcr, Clahpor.iw2 sp., hhor sp., A. Junr igatus, illd Rhizopus sp. were in the following percentages 75, 75,43.7, 3 1.2, 3 1.2,25, 25, 18.7, illid 6.2 respectively. 3- The average contents of Mois ture, crude protein, fat arid ash in diKerent finisher broiler diets were 14.24%, 18.1 1 %, 3.82%, and 6.1 1 % respectively
