Toxicity of excess dicalcium phosphate in the diet of turkey poults

High mortality in 1-week-old commercial turkey poults was attributed to the accidental substitution of dicalcium phosphate in the diet for corn. At necropsy of the affected birds, lesions were observed in the upper gastrointestinal tract, suggesting acute ingestion of a caustic substance. Mortality...

Description
Summary:High mortality in 1-week-old commercial turkey poults was attributed to the accidental substitution of dicalcium phosphate in the diet for corn. At necropsy of the affected birds, lesions were observed in the upper gastrointestinal tract, suggesting acute ingestion of a caustic substance. Mortality and gross and microscopic lesions were reproduced experimentally in turkey poults fed diets similar to the diet fed in the field case. The cause of these lesions was attributed to increased pH due to the phosphoric acid content of the diet. /// Una alta mortalidad en pavipollos comerciales de 1 semana fue atribuida a la sustitución accidental del maíz por el fosfato bicálcido en la dieta. En la necropsia de las aves afectadas, las lesiones se observaron en la parte alta del tracto gastrointestinal, sugiriendo la ingestión aguda de una sustancia cáustica. La mortalidad y las lesiones macro y microscópicas fueron reproducidas experimentalmente en pavipollos alimentados con una dieta similar a la dieta problema. La causa de estas lesions fue atribuida a un aumento del pH debido al contenido de ácido fosfórico en la dieta.
