摘要
研究6头健康新生犊牛3日龄和10日龄时血液某些免疫功能指标的昼夜变化。结果,犊牛3日龄时嗜酸性粒细胞(Eosino)、单核细胞(Mono)和γ-球蛋白(γ-G)(%)夜间12h平均值显著高于昼间(P<0.05);α-球蛋白相反,昼间12h平均值显著高于夜间(P<0.05);白细胞总数(WBC)、嗜中性粒细胞(Neutro)、淋巴细胞(Lymph)、嗜碱性粒细胞(Baso)、总球蛋白(T-G)、β-球蛋白(β-G)、白蛋白(A)昼夜间平均值有差异,但差异不显著(P>0.05)。10日龄时只有嗜酸性粒细胞和单核细胞夜间显著高于昼间(P<0.05)。结果说明昼夜环境节律性变化对新生犊牛免疫功能有明显影响,而且具有年龄性变化特点。
Six spontaneously delivered Holstein calves with a birthweight of 40～50 kg were chosen and a jugular vein catheter wasinserted within 12 hours after birth.The circadian and developmentalchanges of some immune indexes were studied on the age of 3rd and 10thday. The results showed that the average levels of Eosinophils(%),Monocytes(%)and r-Globulin(%) during 12 hrs of night were sinficantly higher than that of day on the 3rd day of age ,while or-Globulin (%) was higher during day, only Eosinophils(%) and Monocytes(%) during 12hrs of night were higher than that of day on the 10th day of age.T-Lymphocytes(%) was realtively lower at the time of 0.4:00-0.6:00 on 3rd day and 10th day of age.
