Summary
The poultry forages and their components were collected
from chicken – runs and forages storages at AL – Hurr and AL- Husseinya regions during January month at year 2004 . Three hundred ninty six isolates were isolated from poultry forages and their components during the period of study , the deuteromycetes showed the highest percentage , followed by zygomycetes and black and white mycelium isolates .
No significant differences appeared in the number of
isolates between the chicken – runs and between the poultry ration storages at AL- Hurr and AL- Husseinya regions , neither
the temperature of chicken – runs and forages storages , nor , the
moisture contents of the forages and their components , affected
on the number of isolates , where weak correlation between these components was found .
The fungi isolation are comprehended (11) genera and (19) species , in addition to black and white mycelium isolates . The most fungi genera occurrence in chicken – runs at Al – Hurr region was Aspergillus genus , followed by Penicillium
and Rhizopus , while the most genera occurrence in chicken – runs at AL – Husseinya region was both Aspergillus and
Penicillium genera followed by both Allescheriella and Rhizopus genera . In the forages storages at AL – Hurr region , Aspergillus genus was the most genera occurrence , followed by Penicillium and Allescheriella , while Rhizopus genus appeared in the third order in the forages o f AL – Husseinya region . The most fungi species frequency in chicken – runs at AL – Hurr region was Aspergillus niger followed by Penicillium restrictum , while the fungus A . fumigatus came in the second order in the chicken – runs at AL – Husseinya region . In the forages storages at AL- Hurr region A . niger was the most fungi frequency in that storages , followed by P . sp1 . and Aspergillus terrus . While the fungus Rhizopus sp . was in the third order of the forages storages at AL – Husseinya region . The most fungi intensity and distribution
in chicken – runs at Al – Hurr region was Aspergillus niger , while the most fungi intensity were A . niger , A . fumigatus and P . sp .1 , in Al – Husseinya region , the most fungi intensity were A . niger , P . sp .1 and A. terrus , in the forage storages at Al – Hurr region , while the most fungi intensity and distribution in the forages storages at AL – Husseinya region
were A . niger , P . sp .1 and Rhizopus sp .
Four species of fungi were selected to extractive
the extracts from them , and these fungi consisted of
Aspergillus candidus , A . fumigatus , A . niger and Paecilomyces lilacinus .
Four – day – old Broilers ( Hubbard Flex ) were fed with extracts of these fungi at the rate of ( 1 ml / 50 gm ) of body weight divided into three groups each group consist fifteen replicate , all of these fungi extracts didn’t affect the weight rates of the birds after ten days from starting dose , while the effect appeared after twenty four and thirty eight days after treatment with the fungi extracts dose , the extract of
A . candidus , A . fumigatus and A . niger decreased the weight rate of the birds , but the extract of Paecilomyces lilacinus didn´t significantly affect their weight rate . Also the extract of A . candidus , A . fumigatus and A .niger , decreased the relative weight of the livers of these broilers treated after ten and thirty eight days , but the extract of Paecilomyces lilacinus didn´t significantly affect them . Steady case in the relative weight of the livers of these broilers was noticed after twenty four days from the adminstration
of the fungi extracts dose , the fungi extracts didn´t effect on the relative weight of the kidney of these birds in all three periods .
Histologically , The fungi extracts caused degeneration changes in the hepatic cells with congestion of central vein and haemorrhage , while the same effect appeared in the Renal cells
and the effect increased with time
