摘要
选用１２只自然分娩、初生重１．５—４．５ｋｇ的新生湖羊羔为对象，研究了生后２４ｈ内血液某些免疫功能指标变化特点。结果表明：羔羊生后２４ｈ内ＷＢＣ明显升高；中性粒细胞（％）生后１ｈ较低，８ｈ内明显升高，以后相对稳定，淋巴细胞和单核细胞（％）与中性粒细胞呈相反关系变化，淋巴细胞中Ｂ淋巴细胞比例１２ｈ内明显上升，以后下降，Ｔ淋巴细胞比例变化与其相反；血浆ＴＰ、Ａ、Ｇ、ｒ—Ｇ含量在生后１ｈ均较低，８ｈ吃初乳后明显升高，以后ＴＰ保持相对稳定的高水平，Ａ呈下降趋势，Ｇ特别是ｒ－Ｇ进一步上升。
Twelve spontaneously lambing Hu --sheep neonatal lambs with a birth weight of 1.5-4.5 kg were chosen to study some characteristics of blood immune-- indexes during the first 24h after birth. The results showed that total leukocyte counts (WBC) increased obviously within 24h of age after births Neutrophiles (%) were low at 1h, rose apparantly during 8h of age after lambing, and remained fairly stable levels thereafter, while the percentages of lymphocytes and monocytes appeared to change inversely; B-lymphocytes (%) increased obviously within 12 h of age after birth, and then desreased, meanuhile, Tlymphocytes(%) appeared to change inversely; Plasma total protein-(TP) albumin (A), globulin (G) and γ--globulin (γ--G) concentrations were lowest at 1 h after birth, increased significantly after the colostrum feeding at & h of age, with TP remaining a steadily high level,A tending a decrease and γ--G increasing further thereafter in lambs.
