【摘要】：【目的】检测桂科育成猪的血常规指标,明确不同功能细胞(红细胞、白细胞和血小板)的数量变化及形态分布情况,为桂科猪的免疫评估与抗病性能研究提供基础数据。【方法】于49日龄起每周对44头桂科育成猪(公母各半)采血1次,连续采样7周,测定其血常规指标,并与长白猪和恩施黑猪的血常规指标进行比较分析。【结果】在桂科育成猪不同日龄的红细胞类检测指标中,红细胞计数(RBC)和血红蛋白含量(HGB)均在70日龄达最低值(6.85×1012/L和97.1 g/L),显著低于49、56、63、84和91日龄时的对应值(P0.05,下同);平均红细胞血红蛋白(MCH)和平均血红蛋白浓度(MCHC)的变化规律基本一致,均在70日龄达最低值(15.11 pg和275.70 g/L)、91日龄达最高值(16.40 pg和314.30 g/L);红细胞压积(HCT)、平均红细胞体积(MCV)和红细胞体积分布宽度(RDW)的变化相对较稳定,不同日龄间均无显著差异(P0.05,下同)。在白细胞类检测指标中,白细胞计数(WBC)于63日龄达最低值(13.71×10~9/L)、84日龄达最高值(17.52×10~9/L),二者差异显著;中性粒细胞计数(NEUT)在70日龄时达最低值(3.61×10~9/L),显著低于49和56日龄的对应值。淋巴细胞计数(LYMPH)的变化相对较稳定,受日龄增长的影响不显著。在血小板类检测指标中,血小板计数(PLT)、血小板压积(PCT)及血小板平均分布宽度(PDW)在不同日龄的变化相对较稳定,受日龄增长的影响不显著。与35日龄长白猪和5月龄以上恩施黑猪相比,桂科育成猪除HCT、平均血小板体积(MPV)、PCT和PDW等少数指标表现异常外,其他大部分血常规指标介于长白猪与恩施黑猪血常规指标范围内。【结论】桂科育成猪在血常规指标方面有一定的独特性,发育至49~91日龄时已具备较稳定的免疫系统。
[Abstract]:[objective] to detect the blood routine indexes of Gui family pigs, and to determine the quantity changes and morphological distribution of different functional cells (red blood cells, white blood cells and platelets). [methods] Blood samples were collected once a week from 49 days of age in 44 adult pigs (half male and half female) for 7 weeks, and their blood routine indexes were measured. The blood routine indexes of Landrace pig and Enshi black pig were compared and analyzed. Red blood cell count (RBC) and hemoglobin content (HGB) reached the minimum value of 6.85 脳 1012 / L and 97.1 g / L at 70 days old, which were significantly lower than the corresponding values (P 0.05) at the ages of 49 / 10 ~ 56 ~ 63N ~ (84) and 91 days, respectively. The variation of mean erythrocyte hemoglobin (MCHC) and mean hemoglobin concentration (MCHCC) was basically the same. At the age of 70 days, the minimum values were 15.11 PG and 275.70 g / L ~ (-1), the highest values were 16.40 PG and 314.30 g / L ~ (-1) at 91 days of age. The changes of HCT (mean RBC volume) and RDW (RDW) were relatively stable, and there was no significant difference between different ages (P0.05). The white blood cell count (WBCC) reached the lowest value (13.71 脳 10 ~ (9) / L ~ (-1) at 63 days of age and reached the highest value of 17.52 脳 10 ~ (9 / L) / L ~ (-1) at 84 days of age, and the neutrophil count reached a minimum value of 3.61 脳 10 ~ (9) / L ~ (-1) at 70 days of age, which was significantly lower than the corresponding value of 49 and 56 days. The change of LYMPH was relatively stable, but not significantly affected by the increase of age. The platelet count (PLT), platelet pressure-accumulated (PCT) and platelet mean distribution width (PDW) were relatively stable at different ages, but not significantly affected by the increase of age. Compared with 35 day old Landrace pigs and 5 month old Enshi black pigs, the average platelet volume and PDW of Gui family were abnormal except for HCT, MPV and PDW. Most of the other blood routine indexes were within the range of the blood routine indexes of Landrace and Enshi black pigs. [conclusion] the blood routine indexes of Gui family are unique, and they have a stable immune system by the age of 490-91 days.
