Resumen
La enfermedad de Circovirus porcino tipo 2, que afecta principalmente a los
lechones, generando disminución en los parámetros productivos, morbilidad y
mortalidad.
Actualmente, una de las opciones, tanto para el aspecto profiláctico, son las
vacunas comerciales, pero muy a pesar de su uso, no ha sido suficiente para
erradicar o por lo menos controlar la enfermedad, debido a motivos como los
títulos de anticuerpos maternales, la necesidad de personal capacitado para la
vacunación, el inadecuado manejo de las vacunas, etc.
Por ello, surge la tesis presente que tiene por objetivo determinar los beneficios
de utilizar como alternativa profiláctica, una vacuna recombinante de Circovirus
porcino, basada en un vector, sobre los índices productivos y sanitarios en
lechones en fase de recría. Instaurándose tres tratamientos, (T1: control, T2
vacuna comercial, T3 Vacuna vectorizada SalvacCirco PCV2), iniciando la
inmunización de los lechones, previa evaluación de los títulos de anticuerpos y
pesaje, repitiendo las evaluaciones los días 40 y 70 de edad. Encontrándose que
el tratamiento con la Vacuna Vectorizada PCV2, se obtuvieron altos niveles de
anticuerpos (1153,75) incluso al día 70 de edad, de igual manera se obtuvieron
mejores resultados en cuanto a los índices productivos.
Porcine circovirus type 2 disease, which mainly affects piglets, causing a decrease in productive parameters, morbidity and mortality. Currently, one of the options, both for the prophylactic aspect, are commercial vaccines, but despite their use, it has not been enough to eradicate or at least control the disease, due to reasons such as maternal antibody titers, the need for trained personnel for vaccination, the inadequate vaccine management, etc. For this reason, the present thesis arises, whose objective is to determine the benefits of using a recombinant porcine Circovirus vaccine, based on a vector, as a prophylactic alternative, on the productive and health indices in piglets in the rearing stage. Establishing three treatments, (T1: control, T2 commercial vaccine, T3 SalvacCirco PCV2 vectorized vaccine), initiating the immunization of the piglets, after evaluating the antibody titers and weighing, repeating the evaluations on days 40 and 70 of age. Finding that the treatment with the PCV2 Vectorized Vaccine, high antibody titers (1153.75) were obtained even at day 70 of age, in the same way better results were obtained in terms of productive indices.
