Abstract
Background and Objective: The common helminthic parasitic infections in livestock cause extensive economic losses to the livestock industry annually around the world, such as Iran. The aim of this study was determined the prevalence of liver and lung parasitic infections of slaughtered cattle in the slaughterhouse of Bavi county.
Materials and Methods: In this descriptive and analytical study, the liver and lungs of 680 slaughtered cattle were directly macroscopical examined in order to evaluation the parasitic infections in the slaughterhouse of Bavi county from the October to December of 2022. Also, the protoscolices in observed hydatid cysts were evaluated in terms of fertile by staining with 1% eosin under the microscope, the fertile protoscolexes were distinguished from the infertile cases by not accepting the dye.
Results:
In the inspection of 680 slaughtered cattle, 151 carcasses (22.06%) were infected with liver and lung parasites, so that 123 livers (18.09%) and 41 lungs (6.03%) were infected with parasites. The highest and lowest rates of parasitic infection in cattle in the slaughterhouse of Bavi county were 37.08% in December and 28.48% in October, respectively. The examination of liver flukes infection of cattle was showed that Fasciola spp and Dicrosolium dendriticum infection in the liver of cattle were 2.9% and 0%, respectively. Also, the contamination of hydatidosis in slaughtered cattle was 15.15%, the infection in liver and lung tissues of cattle were 15.15% and 6.03%, respectively. Also the liver and lung tissues of 2.2% of the cattle were simultaneously infected with hydatid cysts. The fertility of hydatid cysts of liver and lung were 78.64 and 26.83% respectively.
Conclusion: The degree of improvement of the cultural level of livestock breeders and the need to change the traditional methods of animal husbandry and the basic maintenance of livestock are effective in reducing the amount of parasitic infection in cattle.
