A serological study was conducted to identify the age of highest infection with Mycoplasma hyopneumoniae, in swine under intensive rearing system in the Lima province, during the period April – august, 2002. Blood samples were collected fortnightly from 30 piglets from birth till 16 months of age. The commercial test ELISA CHEKITâ-Hyoptest-II, was used for the detection of antibodies. The 66.7 % (20/30) of the animals showed antibodies against M. hyopneumoniae, where 55 % (11/20) seroconverted at 12 weeks of age whereas 5 % (1/20), 30 % (6/20) and 10 % (2/20) seroconverted at 10, 14 and 16 weeks of age, respectively. It is concluded that exist a critical period between 9 and 10 weeks of age, in which M.hyopnuemoniae, began the infection, conducing to the seroconversion. Was demonstrated too, that don’t exist effect in the infection time from sex and number of partitions of the swine’s dam.
