Abstract

The aim of this study was to determine the prevalence of M. hyopneumoniae infection in suckling pigs. Nasal swabs were collected from 300 suckling pigs originating from five farrow-to-finishing farms. One farm had a confirmed PRDC problem (farm A) and four other farms previously had a PRDC problem (farms B, C, D and E). Thirty (30) lactating sows in parity 1, 2 and 3 were selected from each farm (Ten sows per parity). Two piglets from each sow were randomly sampled for nasal swab at 3 weeks of age. The samples were analyzed by the nested PCR technique. Forty five per cent (27/60) of nasal swabs from farm A were found positive. On the other hand, a total of 2.08 per cent were found positive (5/240) from farm B, C, D and E. The tendency of piglet infection per sow by parity showed that first parity had more prevalence than the second and the third parity (60%, 55%, 20%), respectively. We have found a correction between M. hyopneumoniae early infection in suckling pigs and a confirmed PRDC problem (farm A) as oppose to farms that did not have a PRDC problem. The strategies to prevent M. hyopneumoniae early infection are to maintain good lactation, antibiotic prevention program and early M. hyopneumoniae vaccinatio
