espanolLa calidad del aire es un factor importante en la ganaderia intensiva, ya que el aire es el principal vehiculo para la difusion de agentes fisicos, quimicos y biologicos que afectan la salud y el bienestar de los animales y los humanos. El amoniaco es el principal gas contaminante generado en la produccion avicola. En este estudio, se realizo una revision de la literatura con el fin de resaltar cada etapa de transformacion de nitrogeno en la produccion avicola, explicando los mecanismos de conversion desde la ingestion de proteina cruda hasta la volatilizacion en la atmosfera como gas de amoniaco. En resumen, estos pasos son: sintesis de acido urico y excrecion por las aves de corral; mineralizacion de nitrogeno presente en excretas; volatilizacion de amoniaco de la basura. De esta revision, queda claro la importancia de conocer las fuentes y los procesos involucrados en la generacion y emision de amoniaco en las aves de corral y, por lo tanto, adoptar medidas asertivas que puedan minimizar los impactos negativos causados por la emision de amoniaco EnglishAir quality is a major factor in intensive livestock management because air is the main vehicle for the dissemination of physical, chemical, and biological agents that affect the health and welfare of animals and humans. Ammonia is the main gaseous pollutant generated in poultry production. In this study, a literature review was conducted to highlight each nitrogen transformation stage during poultry production, while explaining the conversion mechanisms from the ingestion of crude protein to nitrogen volatilization into the atmosphere as ammonia gas. In summary, the steps for the synthesis of uric acid and the excretion of poultry, mineralization of nitrogen present in excreta, and volatilization of ammonia from litter are presented. Based on this review, the importance of understanding the sources and processes involved in ammonia generation and emission in poultry production is clear, thereby allowing the adoption of assertive measures that could minimize negative effects caused by ammonia emission
