Poultry, especially chickens, are a key source of animal protein and income for rural families, particularly those living below the poverty line. Chickens efficiently convert waste into protein and require minimal resources. However, they are susceptible to helminth (parasitic worm) infections, especially cestodes (tapeworms), which can harm their health and reduce productivity, even without obvious disease symptoms.
These parasites, particularly in layer chickens (not broilers), affect growth, cause organ damage, and lead to economic losses. The severity depends on the type and number of parasites. Common symptoms of heavy infection include weight loss, diarrhea, anemia, and even death.
A study was conducted in Mehkar Tehsil from June 2022 to January 2023 to assess the prevalence of gastrointestinal parasites in chickens. Samples from 147 chickens were collected from poultry stalls and analyzed using microscopic and flotation methods. A total of 59 cestode parasites (identified as Cotugnia) were found—24 during monsoon and 35 during winter—mostly in layer chickens.
The study emphasizes the need for proper parasite identification and control to improve poultry health and productivity. It also touches on the role of biochemistry in understanding parasitism, focusing on biomolecules like carbohydrates and lipids, and their function in living organisms.
Conclusion
All chickens (except broiler chickens) were found to have endemically contracted cestode parasites, according to the analysis. This could be related to subpar veterinary care and poor management practices. In addition to correct bird nutrition, hygienic practices, intermediate host removal, and routine deworming of all poultry are advised for improved health and productivity. The results of this study showed a wide range of cestode infections. need to be aware of the sellers and markets of poultry farms. The widespread prevalence of cestode parasites in chickens, particularly Cotugnia, is a significant concern for poultry farmers. This high infection rate, exacerbated by free-range farming and poor sanitation, negatively impacts the health and productivity of chickens, leading to economic losses. Therefore, effective control measures, including improved poultry management and intermediate host control, are crucial for mitigating the detrimental effects of these parasites.
