Abstract

Poult enteritis mortality syndrome (PEMS) has been an economically devastating disease in North Carolina since the early 1990s. Though much is known about the disease, many questions remain unanswered about the syndrome, including its cause, transmission of causative agent(s), and control methods. This study was designed to investigate the association between PEMS and farm management factors. A prospective longitudinal study was conducted by collecting farm data and monitoring weekly mortality in 54 commercial turkey flocks raised in PEMS-affected regions. Univariate and multivariate statistical analyses revealed that enhancing rodent control methods was negatively associated (P = 0.0228) with PEMS. /// El síndrome de mortalidad y enteritis en pavos ha sido una enfermedad con consecuencias económicas devastadoras para la industria avícola de Carolina del Norte desde el inicio de la década de 1990. Aunque cada día se conoce más acerca de la enfermedad, aún quedan muchas preguntas sin contestar, incluyendo su causa, transmisión del agente causal y los métodos de control. Este estudio se diseñó para investigar la asociación entre el síndrome de mortalidad y enteritis en pavos y los factores de manejo en las granjas. Se realizó un estudio longitudinal tomando datos de las granjas y supervisando la mortalidad semanal en 54 lotes de pavos comerciales criados en regiones afectadas por el síndrome. Los análisis estadísticos uni y multivariados revelaron que mejorando los métodos de control de roedores estuvo negativamente asociado (P = 0.0228) con el síndrome.
