从出生后第1天至50日龄，每天测定新生儿和断奶仔猪粪便分泌性免疫球蛋白A （slgA）的浓度。粪便slgA浓度从出生第1天湿粪便的10(4)μ g/g水平开始，在出生后几天内增加到最大值，可达10(5)μ g/g。在接下来的10天内，该数值不断下降至10(1)~ 10(2)μ g/ g之间，直至断奶。粪便中的slgA水平一直很低，直到至少50日龄。断奶前或断奶后仔猪的脆弱性可以部分解释为肠道中低水平的slgA。
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.
