Abstract
El objetivo de la investigación fue determinar la eficacia de tres vacunas contra parvovirosis y su efecto sobre los parámetros reproductivos en marranas Camborough, evaluándose 375 marranas y sus camadas, con 125 marranas por tratamiento, se les inoculó vacunas identificadas como A, B y C a los 83 días de gestación. Se evaluó los títulos de anticuerpos con la prueba de Elisa. No se hallaron diferencias significativas (P>0.05) entre tratamientos antes de la vacunación, pero 21 días post vacunación se determinaron diferencias altamente significativas (P<0.01), logrando el tratamiento B el mayor valor con 7438.8; 5147.7 y 5329.5 para A y C respectivamente. El efecto de la vacunación se valoró mediante el porcentaje de Eficacia de los anticuerpos, siendo la B superior con 44.5 % y A y C con 0 y 3.4% respectivamente. Para el número de lechones nacidos totales, nacidos vivos, y destetados hubo diferencias altamente significativas (P<0.01), siendo B superior, con promedios de 15.3, 16.9 y 15.5; 13, 14.4 y 13.6 y 11.7, 12.7 y 11.9, para A, B y C respectivamente. El menor número de lechones momificados fue para B y C (P<0.01). Para peso de la camada al nacimiento con promedios de 20.2k, 17.1k y 15.8k para B, A y C (P<0.01). En el porcentaje de fertilidad, no retorno y el porcentaje de partos no se hallaron diferencias (P>0.05). Por lo tanto, se concluye que la vacuna B es más Eficaz para el control de la parvovirosis, mejora parámetros productivos y reproductivos en las marranas Camborough.
ABSTRACT The objective of the research was to determine the efficacy of three vaccines against parvovirus and their effect on the reproductive parameters in Camborough sows, evaluating 375 sows and their litters, with 125 sows per treatment, inoculated with vaccines identified as A, B and C at 83 days of gestation. Antibody titers were evaluated with the Elisa test. No significant differences (P>0.05) were found between treatments before vaccination, but 21 days post vaccination highly significant differences (P<0.01) were determined, with treatment B achieving the highest value with 7438.8; 5147.7 and 5329.5 for A and C respectively. The effect of vaccination was assessed by the percentage of antibody efficacy, being B superior with 44.5 % and A and C with 0 and 3.4% respectively. For the number of piglets born total, born alive, and weaned there were highly significant differences (P<0.01), with B superior, with averages of 15.3, 16.9 and 15.5; 13, 14.4 and 13.6 and 11.7, 12.7 and 11.9, for A, B and C respectively. The lowest number of mummified piglets was for B and C (P<0.01). For litter weight at birth with averages of 20.2k, 17.1k and 15.8k for B, A and C (P<0.01). For fertility percentage, non-return and calving percentage, no differences were found (P>0.05). Therefore, it is concluded that vaccine B is more effective for the control of parvovirosis, improving productive and reproductive parameters in Camborough sows. Keywords:
