摘要
２４头太湖猪仔猪（大白×二花脸），在出生后即被隔离分为４组，并分别人工哺喂葡萄糖盐水（ＧＳ组，ｎ＝４）、牛初乳（ＢＣ组，ｎ＝５）、牛常乳（ＢＭ组，ｎ＝６）和自然哺乳（ＰＣ组，ｎ＝９）。前３组在４８ｈ后归圈哺乳。经酶联免疫竞争抑制法测定，牛ＩｇＧ向ＢＣ组和ＢＭ组仔猪血液中的转移分别在２４ｈ和１６ｈ左右达到峰值，为（２８．１９±１５．４６）ｇ／Ｌ和（１２．８９±１．７８）ｇ／Ｌ，以后逐渐下降，归圈自然哺乳后７ｄ，两组仔猪血中均仍有５ｇ／Ｌ左右牛ＩｇＧ残留；ＰＣ组和ＧＳ组未检测到牛ＩｇＧ免疫反应物。同时观察到，哺喂初乳的ＰＣ组和ＢＣ组的仔猪腹泻率均低于ＢＭ组和ＧＳ组。实验猪血涂片白细胞分类计数结果表明，初生时，中性粒细胞为（５７．６４±７．２１）％，淋巴细胞为（４０．５０±６．２５）％。ＰＣ组和ＢＣ组的中性粒细胞在出生后８ｈ内增加，以后呈下降趋势，４８ｈ时分别为（４８．１２±１．０７）％和（５４．２５±３．４５）％；其淋巴细胞在８ｈ时略有下降，后呈上升趋势，４８ｈ时分别为（５０．１７±１．１５）％和（４２．２３±２．７５）％。在生后４８ｈ内，ＧＳ组和ＢＭ组的中性粒细胞增加，淋巴细胞下降；４８ｈ时的中性粒细胞分别为?
Twenty four newborn Taihu piglets were divided into 4 groups and separately fed by glucose saline (GS, n=4), bovine colostrum (BC, n=5), and bovine milk (BM, n=6) within 48 h after birth, then back to sowfold for suckling freely, the last group naturally suckled all the time (PC, n=9). The serum IgG content was measured by ELISA. The results showed that the transfer of IgG to piglet′s serum reached peak value at 24 h for BC (28.19±15.64) g/L and 16 h for BM (12.89±1.78) g/L respectively, then declined. About 5 g/L of IgG in serum of both BC and BM piglets remained on day 9. The percentage of piglets diarrhea in PC and BC were lower than that in BM and GS. At birth, the average of leukocytes differentiation count were neutrophiles (57.64±7.21)%, lymphocyte (40.50±6.25)%. In PC and BC, the neutrophiles increased within first 8 h, then slightly declined to (48.12±1.07)% at 48 h and the lymphocytes increased to (50.17±1.15)% at 48 h. In GS and BM the neutrophiles increased and lymphocytes decreased within 48 h. Monocytes, eosinophiles and basophiles accounted for the least count with less variation in all groups.
