| 摘 要： | 本实验选用初配体重分别为５６．８、７０．１６、８４．２８ｋｇ的雅南小母猪各６头，在怀孕０－８０天、８１天至分娩分别定量采食１．１３、１．６１、２．０９公斤／头·日和１．５７、２．２４、２．９１公斤／头·日来研究孕期营养水平对初生仔猪器官重和血液生化指标的影响。研究结果表明：孕期母体营养水平对初生仔猪心、脑重没有显著影响（Ｐ＞０．０５），对肝、肾、脾有显著影响（Ｐ＜０．０５），胎儿肾、脾生长发育对母体营养水平变化最敏感，肝中等，脑、心不过感；初生仔猪血清总蛋白、清蛋白含量受母体营养水平影响（Ｐ＜０．０５）；葡萄糖则不受影响（Ｐ＞０．０５）；初生仔猪血清总蛋白、清蛋白含量与母体蛋白摄入量呈二次曲线相关，其方程分别为：Ｙ＝－１５１４．７４５＋２４５２．４７７Ｘ１－８３８．６６３Ｘ１２（Ｐ＜０．００１）Ｙ＝－１２８８９．４８＋３０４３３．７７Ｘ２－１７５９０．９５Ｘ２２（Ｐ＜０．０５）（Ｙ为母体蛋白摄入量：克／头·日；Ｘ１、Ｘ２分别为初生仔猪血清总蛋白、清蛋白含量：ｍｇ／１００ｍｌ）；初生仔猪猪血清清蛋白含量可以作为确定孕期母体蛋白需要量的标识；初生长雅仔猪血清葡萄糖、清蛋白、总蛋白含量分别为７１．７２ｍｇ／１００?

| Abstract: | Every six YaNan gilts, which breeding-weight was 55. 84 70. 16 and 84. 24kg respectively, fed 1. 13 1. 61 2. 09kg/h. d during gestation 0 to 80day and 1. 57 2. 24 2. 91kg/h.d during gestation 81 to 114day respectively Liver, kidney and spleen weight of newborn piglets increase significantly with nutrition levels increasing (P<0.05) but that of heart and brain doesn′ t (P>0. 05);development of fetal kidney and spleen is most easily effected by the nutritional levels,then the that of liver, that of the brain and heart is not effected easily, the serum total protein and albumin concentration of newborn piglets are effected by the nutrition levels (P<0. 05). but that of serum glucose is not (P>0. 05);The serum total protein and albumin concentration of newborn piglets relate quadraticly to the Protein intakes of dam,the quadratic equations are Y=-1514. 745+2452.477X1-838.663X1*X1(R*R=0. 999313 P<0. 01) and Y=-12889. 48+30433. 77X2-17590. 95X2*X2(R*R=1. 011966 P<0.05 )respectively (Y-protein intakes of dam. g/h. d; X1 X2──serum, total;protein and albumin concentration of newborn piglets mg/100ml);We found that the serum albumin concentration of newborn piglet is a responsible index to determine the protein requirement of prognancy swine. The serum glucose. albumin and total protein concentration of L X YaNan newborn piglets are 71. 72mg/100ml 0. 864g/100ml and 1. 387g/100ml respectively. |
