摘要：
Use of a porcine circovirus type 2 protein (PCV2) or an immunogenic composition comprising an ORF2 protein of PCV2 for the preparation of a medicament for use in a method of treating a subclinical infection by PCV2 in an individual pig or group of pigs that results in: - a greater increase in weight of fattening pigs, - a reduction in the loss of weight gain in pigs subclinically infected with PCV2, - a reduction in the number of pigs with a viral load included between 104 to 106 copies of genome per ml of serum in a group of pigs subclinically infected with PCV2, - an increase in the average weight gain in a pig or a group of pigs subclinically infected with PCV2 or a reduction in the number of pigs with viral load comprised between 104 to 106 copies of genome per ml of serum, and / or - a reduction in the morbidity rate within a subclinically infected group of pigs or a r eduction of the mortality rate within a clinically infected subgroup of pigs, wherein said method consists of administering a therapeutically effective amount of said medicament to said pig or said group of pigs once, and wherein said subclinical infection by PCV2 is characterized because the viral load in a subclinically infected pig is less than 106 genomic copies of PCV2 per ml of serum and because a sample of 1 ml of serum or 1 mg of tissue from said pig comprises a detectable amount of PCV2 genome equivalents.Uso de una proteína ORF2 del circovirus porcino de tipo 2 (PCV2) o una composición inmunogénica que comprende una proteína ORF2 del PCV2 para la preparación de un medicamento para uso en un método de tratamiento de una infección subclínica por PCV2 en un cerdo individual o un grupo de cerdos que da como resultado: - un mayor aumento de peso de los cerdos en engorde, - una reducción de la pérdida de ganancia de peso en los cerdos subclínicamente infectados con PCV2, - una reducción del número de cerdos con una carga viral comprendida entre 104 a 106 copias de genoma por ml de suero en un
