A study on relationship between strength of biosecurity and disease occurrence in commercial layer farm in Rangpur

Abstract

Biosecurity measures play a crucial role in maintaining the health and productivity of poultry farms especially for layer farming to prevent disease outbreaks and ensure ongoing profitability. Implementing stringent biosecurity practices helps minimize the risk of disease transmission not only among the birds but also to humans and other animals. This study which covered the layer farms of Rangpur Sadar area delves into the intricate association between biosecurity measures with overall disease occurrence and mortality rates in commercial layer farms. In addition, we specifically looked for the association of biosecurity measures with the occurrence of coccidiosis. In this study analysis of different biosecurity parameters such as floor type, footbath usage, disinfectant application, deworming practices, personnel hygiene etc, results that this biosecurity parameter were closely associated with the disease occurrence and mortality rate of chicken in layer farm. Notably from this study, farms which implementing uses of footbath (P<0.02) experienced a 0% disease occurrence rate. Conversely, farms that did not adhere to biosecurity measures saw a significant increase in disease incidence (80-100%) and elevated mortality rates (50-60%). This study also highlights that farms practices regular deworming practices (P<0.001) experienced 0% occurrence of coccidiosis. Ultimately, this study underscores that rigorous biosecurity combined with hygienic measure is essential for maintaining a disease-free environment and achieving optimal outcomes in commercial layer farms.
