    El uso de la inseminaci贸n artificial (IA) se ha incrementado en la crianza porcina contribuyendo al mejoramiento gen茅tico de los planteles de reproductores. Adem谩s, entre sus beneficios se encuentran la disminuci贸n de enfermedades por transmisi贸n sexual y el menor n煤mero de reproductores requeridos; sin embargo, la difusi贸n de esta tecnolog铆a depende en alguna forma de la calidad del semen colectado y procesado. Existen muchos factores que pueden influir directamente sobre la calidad del semen porcino (Garc铆a et al., 1998), entre los cuales se encuentra la contaminaci贸n por microorganismos. La contaminaci贸n bacteriana del semen ocurre habitualmente durante la colecta (Arauz et al., 2000) o puede provenir del aparato g茅nito-urinario, pudiendo causar una disminuci贸n de la eficiencia reproductiva (Serrano et al., 1994).The objective of the present study was to evaluate the bacterial content in semen from 30 healthy boars used as sires in pig farms in the coastal area of southern Lima (Lur铆n). Half of boars were from two technically advanced farms and the other half from one semi technically oriented farm. The gloved-hand method for semen collection was used and the collected semen was filtered to separate the gel fraction. The results indicated that in the technical farms, 73% of ejaculates (11/15) showed bacterial growth and 13% (2/ 15) exceeded the OIE limit of 5,013 UFC/ml, whereas in the non-technical farm , all ejaculates showed bacterial growth and 60% (9/15) exceeded the OIE limit. Pseudomona aeruginosa was the bacteria with higher number of colonies per semen sample and Escherichia coli was the most common bacteria
