摘　　要：选择３２头自然分娩、初生重１ｋｇ～１．５ｋｇ的大白猪×内蒙黑猪杂交Ｆ１代新生仔猪，研究２８ｄ产后期内血清中ＩｇＧ的动态变化。结果表明，仔猪出生后没吃母乳以前血清中的ＩｇＧ甚微（０．１２±０．０５８ｍｇ／ｍｌ），吃完初乳后血清中ＩｇＧ含量迅速升高，到２４ｈ达到峰值（６０．１０±１１．１８ｍｇ／ｍｌ），随后缓慢下降，到２１ｄ（２０．５３±６．４６ｍｇ／ｍｌ），随后又开始上升。Twenty-eight spontaneously delivered, with 1kg-1.5kg birth weight pighets from seven Yorkshire×Inner Mongolia Black sows were used to study the changes in serum IgG content during postnatal period in 28 days of age . The results indicated that, pighets are born with very small serum IgG content(0.12±0.058mg/ml). After suckling of colostrum, the IgG level rose quickly, 24h postpartum mean serum IgG level reached peak value(60.10±11.18mg/ml), then decreased slowly, the leves dropped to a minimum value of 20.53±6.46mg/ml on day 21, serum IgG level tended to rise after 21d postpartum.
