Task: Translation
Input (Spanish): Yo quisiera añadir, no obstante, que no era necesario esperar a disponer de nuevos datos científicos que prueban que la contaminación experimental de ovejas, inducida mediante la alimentación con piensos contaminados con EEB, ha dado origen a manifestaciones clínicas que no se diferencian de la enfermedad del prurigo lumbar.
Output (English): I should, however, like to add that no new scientific knowledge was needed which proved that the experimental infection of sheep by feeding them BSE-infected feed produced a clinical expression of the disease which is indistinguishable from the symptoms of scrapie.
