Thirty two fungal species which belong to 15 genera in addition to fungi withsterile mycelium were collected and identified during this study. Generally the most frequent fungal species encountered from different samples tested were as follows:
Geotrichum candidum; and A. flavus, P. chrysogenum and F. moniliforme, and G. candidum, Scopulariopsis brevicaulis and P. chrysogenum; and A. niger, A. fumigatus, F. oxysporum, A. niger and M. racemosus in rumingal juice samples gained after fed with cotton seed cake mixture (1); bagasse (II); Egyptian clover's stems (III); green broad bean's stems (IV), and green onion's stems (V) respectively.
The clinical examination of the experimental animals was also carried out of ensure the sound of physiological activity. Some groups (1, III and IV) ensure soundness of experimental animals but, depression, relative loss of appetite and weak delayed ruminal contractions was observed in group (II) whereas diarrhea, depression and staggring with accelerate breathing of onionic odour in group (IV).
