Description
Summary:The economic impact of management practices designed to limit the introduction of disease into a parent broiler breeder flock (biosecurity) was evaluated using benefit-cost analysis. Equations were developed to quantify the losses resulting from infection with one of four alternative categories of disease representing incremental levels of pathogenicity. Realistic costs and assumed values relating to the probability of infection were used to evaluate the ameliorative effect of three alternative levels of biosecurity. A microcomputer spreadsheet program was used to confirm that expenditure on protective measures can be justified by both the risk of introducing a disease and the magnitude of losses that may occur following infection. /// Se evaluó el impacto económico de las prácticas de manejo diseñadas para limitar la introducción de enfermedades (bioseguridad) en una parvada de reproductoras pesadas por medio de un análisis de costo-beneficio. Se desarrollaron ecuaciones para cuantificar las pérdidas resultantes de la infección con una de cuatro categorías distintas de enfermedades que representaban niveles de patogenicidad decrecientes. Se utilizaron costos reales y valores supuestos relacionados con la probabilidad de infección para evaluar las mejoras obtenidas con tres niveles distintos de bioseguridad. Se utilizó un programa de computación para confirmar que los gastos en medidas de protección pueden justificarse debido al riesgo de introducir una enfermedad y a la magnitud de las pérdidas que pueden ocurrir después de una infección.
