This study was carried out to determine the presence of gastrointestinal parasites of local ducks and geese in Nineveh province. Sixty-four ducks and seventy geese of different ages and sexes were purchased from local markets. Necropsy findings in ducks reviled a total infection rate of 68.8% was with protozoa, 50% was with nematodes, while 28.1% were with cestodes. On the other hand, in geese, the percentages with the mentioned parasites were 78.6% with protozoa, 54.2% with nematodes, 31.4% with cestodes. Four types of nematodes were identified in ducks; Ascaridia galli, Heterakis gallinarum, Heterakis isolonche, and Subulura brompti, the same were also found in geese except Heterakis.isolonche. Cestodes identified in ducks and geese were Railletina tetragona, Railletina echinobothrda, Railletina cesticillus and Coantaenia infundibulum. The detected protozoa include Eimeria spp., Tyzeria spp., Wenyonella spp., Cryptosporidia spp., Giardia spp. Double infection with parasite was higher in ducks while the triple infection in geese was the higher.

This study included recording the natural heavy infection with immature macrocysts (Sarcocysts) of Sarcocytis spp. in sheep. The sheep is one years old which is slaughtered at butcher shop at Mosul city in May 2018. This is the first case recorded of natural infection with immature sarcocysts of Sarcocystis spp. in Mosul city. Many of small nodules were observed during slaughter, these nodules are seen within esophageal muscles in different sizes and shapes, they were distributed randomly throughout esophageal muscles. Most of the sarcosystis were small in size the mean of size between 20- 28×28-42 µm they were histological examination showed that presence of only metrocytes. This confirmed the diagnosis that the sarcocysts were immature macrocysts (sarcocysts) for the Sarcosystis spp. In our study, heavy infected case with Sarcocystis reveals the fact that large numbers of cats(final hosts) in contact with sheep in pastures is considered the main risk factor for infection and feed with raw meat from infected sheep, which is very important for carcass condemnation when the meat inspection when abnormalities are found which indicate that the part of carcass, is unfit for human consumption it is condemned, which means the economic loss for livestock.

The study was conducted to detect the ectoparasites infestation in chickens, Domestic pigeons Columba livia domestica and turkeys in different areas of Mosul city by survey examining of 80 birds of chickens, 85 birds of pigeons and 50 birds of turkeys, of both sexes. Results show the infestation rates with ectoparasites in chickens, pigeons and turkeys, were 41.3%,37.6% and 36% respectively. Results show that the chickens were infested with three types of ectoparasites, two species of lice are Menacanthus stramineus, Gniocotes gallinae and soft ticks Argas persicus the infestation rates were 63.6%, 24.2% and 36.4% respectively. The highest infestation rate with lice in chicken was 70% in Spring season and the lowest rate 5% in Summer season while the infestation rates in Autumn and Winter were convergent, there was 44.4% and 45.5% respectively. The results show that the pigeons were infested with two types of ectoparasites, one species of lice is Columbicola columbae and soft ticks is Argas persicus, the rates were 87.5%,18.8% respectively. The infestations were individual and double. In turkeys the results record one lice species Goniocotes gallinae, the infestation rates were 36%. The male and female were infested with rates 27.3% and 42.9% respectively.
