Abstract
En el presente trabajo, se estudian las posibles causas responsables de los episodios de mortandad ocurridos entre las vacas reproductoras de una ganadería de lidia ubicada en la Región de Murcia, con el fin de obtener su diagnóstico e implantar las medidas oportunas para su control. El caso estudiado se desarrolló durante el mes de marzo de 2022 coincidiendo con un temporal de intensas y constantes precipitaciones que dificultaron el acceso del ganadero a la finca y, como consecuencia, el correcto manejo nutricional del ganado. El cuadro clínico de las vacas afectadas cursaba con caquexia, debilidad extrema, atrofia muscular y postración en decúbito esternal con imposibilidad para recuperar la estación. Se recabaron los principales datos climatológicos y alimentarios de dicha ganadería durante ese mes, se tomaron muestras de sangre para el estudio del hemograma y bioquímica sanguínea, y se realizó la necropsia de dos animales con la toma de muestras en formol al 10% para el estudio histopatológico. Los animales presentaban atrofia serosa y movilización de grasas, y a nivel bioquímico una hipoglucemia muy marcada junto a descenso de proteínas totales, aumento de enzimas de daño hepático y muscular, urea, bilirrubina y potasio, y un leve descenso de fósforo. El hemograma presentaba indicios de anemia macrocítica e hipercrómica y un leve descenso de las células de la serie blanca. Tras la interpretación de los datos obtenidos, se aporta como conclusión que un deficiente manejo nutricional es un importante agente causal del síndrome de la vaca echada en el bovino de lidia en la fase de periparto, patología no descrita hasta la fecha según la bibliografía consultada para esta raza bovina.
This study examines the possible causes responsible for the mortality episodes that occurred among the breeding cows in a bullfighting cattle farm located in the Region of Murcia. The objective is to diagnose the issue and implement appropriate measures for control. The study was conducted during the month of March 2022, coinciding with a period of intense and constant rainfall which hindered the farmer’s access to the farm and consequently affected the proper nutritional management of the livestock. This nutritional deficit led to episodes of cows being unable to stand up with signs of cachexia, extreme weakness, muscular atrophy and recumbency. The main climatological and feeding data of this livestock during that month were collected, blood samples were taken for haematological and biochemical analysis, and a regulated necropsy was performed with samples taken in 10% formalin for subsequent anatomopathological study. The animals showed generalized serous atrophy and fat mobilisation, biochemically it showed a very marked hypoglycaemia together with a decrease in total proteins, an increase in liver and muscle damage enzymes, urea, bilirubin and potassium, and a slight decrease in phosphorus. The haemogram showed signs of macrocytic and hyperchromic anaemia and a slight decrease in white blood cells. After the interpretation of the obtained results, it was concluded that a de-ficient nutritional management is an important causal agent of the downer cow syndrome of bullfighting cattle in the peripartum phase, a not described to date pathology according to the literature consulted for this breed.
