Abstract
Se describe la aparición de un proceso de raquitismo en cerdos en crecimiento. Los signos clínicos fueron cojeras, fracturas óseas y paraplejía. En la necropsia se apreció engrosamiento de las zonas próximas a la articulación tibiotarsal y las articulaciones costocondrales. Microscópicamente se observó engrosamiento del periostio con presencia de focos de osificación, líneas de osificación irregular y la aparición de lagunas de cartílago
entre el tejido osificado. El análisis del pienso demostró que casi la totalidad del fósforo presente procedía de las materias primas, por lo que no se había añadido ninguna cantidad en el corrector vitamínico-mineral. El diagnóstico final fue de raquitismo asociado a un desequilibrio mineral, determinándose que estaba relacionado con un fallo durante la fabricación del pienso, ya que se había adicionando una décima parte del corrector que figuraba en la fórmula.
ABSTRACT The appearance of a process of rickets in growing pigs is described. The clinical signs observed were lameness, bone fractures and paraplegia. The necropsy revealed thickening of the tibiotarsal and costocondral joints. Microscopically, thickening of the periostium with presence of ossification foci, irregular ossification lines and the appearance of cartilage areas between the ossified tissue was observed. Feed samples were analyzed and was demonstrated that almost the total phosphorum present came from the raw materials and no phosphorum was added in the vitamin-mineral complex. The final diagnosis was rickets due to a mineral imbalance. The problem was due to a error in manufacturing feed. Ten fold less quantity of vitamin-mineral complex of the specified was added to the feed by a transciption error in the formula.
