The concentration of fecal secretory immunoglobulin A (slgA) in neonate and weaning piglets was measured daily from I day after birth to 50 days of age. The concentration of fecal slgA started from the level of 10(4) mu g/g wet feces 1 day after birth and then increased to a maximal value of up to 10(5) mu g/g within a few days of birth. The values constantly declined to between 10(1) and 10(2) mu g/ g for the next 10 days and were relatively constant until weaning. The level of slgA in the feces remained very low until at least 50 days of age. The vulnerability of pre- or post-weaning piglets can be explained, at least ill part, by this low level of slgA ill the intestine.
