In the present study 40 samples of broiler feeds that obtained from commercial feed manufacturing company (concerning 21 from Iraqi manufactures and 19 from the Iranian manufactures) were analyzed for the incidence of Aflatoxins, Ochratoxin, T-2, Fumonisins, and Zearalenone mycotoxins. The result has shown that AF was detected in 16 samples 76.19% of the Iraqi manufactures and 16 samples 84.21% from the Iranian manufactures, in concentrations ranging from 1.00-23.00 μg/ kg, and 1.00-2.00 μg/ kg respectively. Prevalence of AF contamination revealed a significant association (P<0.05) between the Iraqi and Iranian manufactures, the highest prevalence was observed in Iranian samples 84.21%, whereas it least in Iraqi samples 76.19%. OCHRA toxin was detected in 21 samples 100% of the Iraqi manufactures and 19 samples 100% from the Iranian manufactures, in concentration ranging from 3.00-4.00 μg/ kg, and (2.00 – 4.00) μg/ kg respectively. prevalence of OCHRA contamination revealed a non-significant (P>0.05) between the Iraqi and Iranian manufactures. T2 toxin was detected in 21 samples (100%) of the Iraqi manufactures and 19 samples (100%) from the Iranian manufactures, in concentration ranging from (2.00 – 16.00) μg/ kg, and (2.00 – 23.00) μg/ kg respectively. Prevalence of T2 contamination revealed a significant association (P<0.05) between the Iraqi and Iranian manufactures FUM3 toxin was detected in 21 samples (100%) of the Iraqi manufactures and 19 samples (100%) from the Iranian manufactures, in concentration ranging from (0.05 – 5.00) μg/ kg, and (0.10 – 2.50) μg/ kg respectively. Prevalence of FUM3 contamination revealed a significant association (P<0.05) between the Iraqi and Iranian manufactures, ZEAR3 toxin was detected in 15 samples (71.42%) of the Iraqi manufactures and 19 samples (100%) from the Iranian manufactures, in concentration ranging from (2.00 – 76.00) μg/ kg, and (1.00 – 41.00) μg/ kg respectively. Prevalence of ZEAR3 contamination revealed a significant association (P<0.05) between the Iraqi and Iranian manufactures, the highest prevalence was observed in Iranian samples (100%), whereas it least in Iraqi samples (71.42%).

The present study was carried out to evaluate the pathological effects of aspergillosis caused by Aspergillus Spp. in commercial broiler chickens. In this study, we discussed few outbreaks of Aspergillus infection of chicks a week aftter hatching in broiler farms of Duhok-Kurdistan region of Iraq during the period from February to May 2015 on the basis of clinical signs, post-mortem, histopathological and cultural findings. The main clinical signs of the disease in the infected flock included a 3-day onset of labored breathing and neurologic disorders displayed by incoordination, torticollis, and paralysis. Other clinical features included depression, ruffled feathers and gasping. Gross lesions were represented by cheesy granular materials in the air sacs, lungs, and trachea. Histopathology revealed fungal hyphae in sectioned lung tissue. Aspergillus was isolated by culturing in Sabouraud’s dextrose agar from the lesions. The present study deals with the incidence of acute aspergillosis in broiler chicks from Duhok, Kurdistan-Iraq.

Hyperimmunized egg yolk (HIY) was produced in two layer hens by four successive immunization with live attenuated Newcastle disease vaccine (NDV) by seven days intervals for each vaccination process. Fifty broiler chicks were used for treatment with hyperimmunized yolk. They were divided into five groups. The first group was treated at 14th days of age by orally and intramuscular injection (five chicken for each route). The second group was boostered with (HIY) after 7 days of first dose at14 days of age. The third group as that of the first group but treated at 21st day of age. The fourth group was treated at 21st days and boostered after 7 days. The fifth group was ten chicks remain without any treatment used as control comparison of all groups. Immune response was measured using HI technique.The results showed that the group of 14th day of age with booster dose gave high antibody titer by intramuscular injection (second group).
