Resumen

This study was conducted on a commercial farm in Trujillo, Peru, to evaluate the effect of three vaccines against porcine parvovirus on antibody production and the productive and reproductive parameters of sows. A total of 375 multiparous Camborough sows were monitored and randomly assigned to three treatments corresponding to the vaccines: A (ZOS), B (HIP), and C (MDS). Sows selected were between their second and sixth parities, with good body condition, and similar productive and reproductive performance. Two blood samples were collected from each sow: the first, one day before vaccination, and the second, three weeks after the injection. Antibody titers were determined using ELISA. No significant statistical differences were observed in the antibody titers before vaccination (P>0.05). However, at 21 days post–vaccination, highly significant differences were found (P<0.01), with the HIP vaccine showing the highest antibody titers. Among the evaluated productive parameters, including the number of live–born, stillborn, and weaned piglets and litter birth weight, significant differences were detected in favor of the HIP vaccine (P<0.01). Additionally, the sows vaccinated with HIP had fewer mummified piglets (P<0.05). No significant differences (P>0.05) were observed among the treatments in terms of fertility, non–return, or farrowing rates. In conclusion, the commercial HIP vaccine significantly increased antibody titers, improved productive performance, and did not adversely affect reproductive parameters compared to the other two commercial vaccines in Camborough sows. © (2026), (Universidad del Zulia, Facultad de Ciencias Veterinarias).
