Abstract

A flock of 51-week-old leghorn hens experienced a 16% drop in egg production in a single week. The layer ration contained 1477 ppm copper from the addition of copper sulfate. Severe oral ulcers were present in the pharynx. Oral ulcers, reduced feed intake, and a drop in egg production occurred when a ration containing 1437 ppm copper was evaluated experimentally. /// Un lote de ponedoras leghorn de 51 semanas de edad tuvo una baja de producción del 16% en una sóla semana. La dieta contenía 1 477 ppm de cobre debido a la adición de sulfato de cobre. Varias úlceras orales estaban presente en la faringe. Cuando experimentalmente se evaluó una ración que contenía 1 437 ppm de cobre, se observaron úlceras orales, reducción en el consumo de alimento y una baja en la producción de huevos.
