--- Avian infectious laryngotracheitis (ILT) is a disease that currently affects many poultry farms in our country and produces economic losses. The aim of this study was to evaluate the economic losses caused by ILT in a commercial layer farm in the department of Lima. It was performed in a farm located in the district of Chilca, Province of Cañete, Department of Lima, which had a population of 14415 hens stage and was affected by the ILT. A survey was made and visits to the farm were done to collect biosafety data, production data and production costs of a campaign with ILT and a campaign without ILT. Productive parameters were evaluated and the economic impact caused by ILT was measured by comparing costs and lost productivity from both campaigns using a stochastic distribution model with the risk analysis program @ RISK 5.1 ®. It was found that the cost per kg of egg on the campaigns with ILT increased by 34.07%, with respect a campaign without the disease. In the campaign with ILT egg production declined by 16% and mortality increased by 18% when compared with the campaign without ILT. The economic returns were similar in both campaigns, due to the increase of selling prices of eggs and chickens during the campaign with ILT. Otherwise 16% of the proceeds from the sale of eggs and 25% revenue from the sale of hens would had lost, plus costs for the measures taken by the outbreak of ILT. ILT had a negative economic impact on the tested farm, causing significant production losses and economic losses. Keywords: Avian infectious laryngotracheitis, economic impact, production losses, layer farm.
