Porcine reproductive and respiratory syndrome is a great important economic disease characterized by respiratory problems in pigs. The aim of this study was detect antibodies against porcine reproductive and respiratory virus (PRRSV) and associated them by respiratory problems in a batch from tech pig farm in Lima. Serum samples were collected from 30 pigs in a batch of 200 pigs in three consecutive stages at 32, 61 and 136 days old to determine antibody against PRRSV by indirect ELISA test. The Batch studied was daily followed to find respiratory problems. 26.7% (8/30) of samples had antibody anti PRRSV at 32 days old with samples-on-positive coefficient (M/P) among 0.4 to 1.6, at 61 day old only one pig had PRRSV antibodies while the 96.7% (29/30) had antibody against PRRSV at 136 days old. There were no observed respiratory problems in situ in the batch studied in the whole period of observation. The age of animals and anti PRRSV antibodies was associated (P ≤ 0.05). Keywords: PRRSV, ELISA, respiratory problems, pig tech farm.
