摘　　要：This paper first reports that the contents of sIgA,IgG and IgM of 3 giant pandas′colostrums from day 1 to day 14 unconsecutively which have been determined by the method of "A Rate Nephelometer for Measuring Specific Protein by Immunopreciptin Reaction".The results indicated that sIgA is the most important immunuoglobulins of giant panda′s colostrums, and IgG, IgM are also the major components of giant panda′s colostrums. The contents of immunoglobulins in colostrums of giant pandas vary with the day : 1) the content of colostral sIgA is in the highest level (1 442.93 mg/dl) in lst day, and maintains a higher level(1 200-1 300 mg/dl) from 2nd day to 5th day,it drops abruptly in 7th day (727.61 mg/dl); 2) the content of colostral IgG is in the hingest level(861.5 mg/dl),and maintains in a higher level(648.74-707.07 mg/dl) from 2nd day to 5th day,but drops abruptly in 7th day (375.14 mg/dl);3) the content of colostral IgM varies rarely and maintains in a stable level during the first postpartum 5 days,and drops abruptly in 7th day . Based on the changes of immunoglobulins in giant panda′s milks, the author conclude that milks from 1st day to 5th day postpartum should be giant panda′s colostrums.This paper first reports that the contents of sIgA,IgG and IgM of 3 giant pandas′colostrums from day 1 to day 14 unconsecutively which have been determined by the method of 'A Rate Nephelometer for Measuring Specific Protein by Immunopreciptin Reaction'.The results indicated that sIgA is the most important immunuoglobulins of giant panda′s colostrums, and IgG, IgM are also the major components of giant panda′s colostrums.
