Resumen:	Gilts are considered to play a key role in Mycoplasma hyopneumoniae (M. hyopneumoniae) transmission and control. An effective gilt acclimation program should ideally reduce M. hyopneumoniae shedding at first farrowing, decreasing pre-weaning colonization prevalence and potential respiratory problems in fatteners. However, information on gilt acclimation practices is scarce in Europe. The aim of this study was to identify current acclimation strategies for M. hyopneumoniae in Europe using a questionnaire designed to assess 15 questions focused on gilt replacement status, acclimation strategies and methods used to ascertain its effect. A total of 321 questionnaires (representing 321 farms) were voluntarily completed by 108 veterinarians (from 18 European countries). From these farms, 280 out of 321 (87. 2%) were aware of the health status of gilts on arrival. From these 280 farms, 161 (57. 5%) introduced M. hyopneumoniae positive replacements. In addition, 249 out of 321 (77. 6%) farms applied an acclimation process using different strategies, being M. hyopneumoniae vaccination (145 out of 249, 58. 2%) and the combination of vaccine and exposure to sows selected for slaughter (53 out of 249, 21. 3%) the most commonly used. Notwithstanding, only 53 out of 224 (23. 6%) farms, knowing the M. hyopneumoniae initial status and performing acclimation strategies against it, verified the effect of the acclimation by ELISA (22 out of 53, 41. 5%), PCR (4 out of 53, 7. 5%) or both (27 out of 53, 50. 9%). This study showed that three fourths of the farms represented in this European survey have M. hyopneumoniae acclimation strategies for gilts, and one fifth of them verify to some extent the effect of the process. Taking into account that the assessment of acclimation efficacy could help in optimizing replacement gilt introduction into the breeding herd, it seems these practices for M. hyopneumoniae are still poorly developed in Europe.
