Among the regions, Layyah had a prevalence rate of 12.0%, Muzafargarh had 14.0%, Multan had 11.2%, and Khushab had 11.9%. Factors such as flock size, poultry breeds, biosecurity measures, and vaccination coverage were identified as significant influences on ND occurrence. Notably, small flocks (less than 50 birds) had a prevalence rate of 13.33%, medium-sized flocks (50-100 birds) had 11.11%, and large flocks (more than 100 birds) had 11.90%. Local breed flocks had a prevalence rate of 5.00%, hybrid breeds had 11.11%, and exotic breeds had 20.19%.</p> <p><strong>Conclusion: </strong>The study provided valuable insights into ND prevalence and associated factors, facilitating the development of targeted control and prevention strategies for backyard poultry populations in Pakistan.</p>}, number={01}, journal={Indus Journal of Animal and Plant Sciences}, author={Mubarik Ali and Norina Jabeen}, year={2023}, month={Jun.}, pages={21–27} }
